This instruction explains the repair welding and all the connected tasks step by step. 1 2 1 PW Crane Important information about welding repairs www.palfinger.com 7 3 Important information about welding repairs PLEASE NOTE Chapter 4 of the installation guideline “Welding on bodywork and crane” must be obeyed. The installation guideline is available on PALDESK. Chapter 3 includes important facts about welding related to the repair which must be obeyed. Ensure to clearly understand those basic guidelines. 3.1 General  Working- and safety standards must be respected, especially the issue fire prevention.  Provide fire extinguisher during the repair work.  Ensure repair area is clean and free of paint before starting welding works.  Grind out cracks according to specifications in this instruction.  Clean and process the welding gap.  Welding under the terms of available WPS (Welding Procedure Specification) according to EN ISO 15613 or EN ISO 15614 or similar valid regulations.  After the repair the area must undergo a verification. 3.2 Welder’s qualification, documentation The needed welder’s qualification for the repair are following:  EN 9606-1 135 P FW FM2 S s8 PF ss sl mb  EN 9606-1 135 P BW FM2 S s10 PC ss ml nb  In case of other country specific standards and regulations, the valid welder qualification must be at least the same level or an higher level as the standards mentioned above.  In general the welder is self-responsible to ensure appropriate welding quality. PALFINGER requires the following documentation for each case:  To proof the carried out repair work and to document the case, a picture of the final repair work has to be taken before painting.  This has to be included to the warranty claim (refer to recall R-NC-2103). 3.3 Component material The crane base and the reinforcing plate are both made of the following material:  Sheet metal S690 Important information about welding repairs PW Crane 8 www.palfinger.com 3.4 Reinforcing plate To carry out the repair, a reinforcing plate has been designed and has to be ordered from the PALFINGER parts center. The part number of the reinforcing plate is HA22914. Illustration 09-53- 2: Reinforcing plate HA22914 3.5 Filler material The welding must be carried out using the following filler material:  Welding wire (PALFINGER standard „Z2“) Böhler X70-IG / ISO 16834-A: G 69 5 M Mn3NiCrMo with 1 mm wire diameter.  Welding wire (PNAG standard „E110“) Lincoln Electric SUPERARC LA-100 / AWS A5.28: ER110S-G.  PALFINGER part number for the welding wire (Böhler) is W10007363 (18kg coil).  For MAG M welding, protective gas M20 or M21 according to EN 14175 must be used. 3.6 Preheating temperature / interpass temperature  The temperature in the welding area must be at least 20 °C (68 °F). If the environment temperature is less than this, preheating is required.  The allowed maximum interpass temperature is 150 °C (302 °F).  In general the definition of the correct temperature range is the responsibility of the welding supervisor in charge. 3.7 Welding parameter  The welding parameters must be selected and set by the responsible welding engineer who is performing the repair welding. PW Crane Preparation work www.palfinger.com 9 4 Preparation work 4.1 Accessibility It is of essential importance to have access to the affected area during all repair works. Therefore removing the crane might be necessary (especially on front mounted cranes, as on most vehicles in the US). On rear installations (as most common in Canada), sufficient accessibility might be given by just removing the balance. It is in the responsibility of the welder and his supervisor, to decide, if a removal is necessary or not. 4.2 Working steps The following steps are required in any case, whether a crack is present or not.  Remove the crane if necessary (refer to point 4.1) using proper equipment and place it safely.  Remove the balance to grant accessibility.  Dismount attached parts interfering the working area. IMPORTANT INFORMATION The repair weld can be carried out with the column in place. There is no need to take out the column on assembled cranes.  Clean the working area properly, especially remove all grease.  To avoid damage to the surrounding area, take appropriate precautions.  Protect the nearby area with welding blankets or something similar while carrying out the repair work.  Provide fire extinguisher (refer to point 3.1).  Take off the part identification plate (1). This plate must be reinstalled on a different position after the work is finished.  Use grinder to remove the paint, the area has to be blank, clean and free of grease (2). Illustration 09-53- 3: Remove part plate Illustration 09-53- 4: Grinded welding area, ready for repair work The preparation work is now completed. 1 2 Repair work PW Crane 10 www.palfinger.com 5 Repair work The following chapter describes how to carry out the repair work in detailed steps. The chapter is divided in two sub-chapters: ➔ Crack repair (only applicable, if a crack is present) ➔ Reinforcing plate (always applicable) If no crack is present, skip chapter “5.1 Crack repair”. IMPORTANT INFORMATION If the situation is uncertain whether a crack is present or not, use a dye penetration test for verification (if this method is not clear, contact PALFINGER for guidance). 5.1 Crack repair This chapter is only valid, if a crack is present (before adding the reinforcing plate HA22914 it is essential to repair the crack).  Grind out the crack (1) over its entire length with a minimum depth of 6 mm (¼’’) and a maximum depth of 10 mm (⅜’’).  It is allowed, that a lack of penetration of 2 mm (1/16’’) is still visible after grinding in a depth of 10 mm (⅜’’).  Be aware that the plate has a thickness of 12 mm (½’’). Do not grind completely through the plate.  Grind out the crack over its entire length. Illustration 09-53- 5: Area after grinding CAUTION Only cracks not touching the critical zone are repairable. If a crack touches the critical zone, the base must be changed. 1 PW Crane Repair work www.palfinger.com 11 Definition of the critical zone A crack (2) is in the critical zone if it reaches into the critical area (1) in either the right or the left side. This area (1) is 70 mm (2¾”) long on each side, measured on the welding seam from the outside towards the center. Illustration 09-53- 6:  In uncertain cases, use a dye penetration test to clearly identify whether a crack touches the zone or not.  Place an appropriate welding seam (3) onto the grinded out area.  Grind area even (4) so the reinforcing plate can be placed properly afterwards. 3 Welding seam 4 Grinded weld Illustration 09-53- 7: Affected area After the crack is rewelded and grinded even, further points must be checked before the reinforcing plate is installed. 3 4 1 1 2 Repair work PW Crane 12 www.palfinger.com 5.2 Reinforcing plate 5.2.1 Filled welding seam area Because of the design and the welding specifications, the affected area can show itself with or without a “filled” welding preparation. A filled welding preparation is given, if the welding seams completely fill the welding seam area to the edge of the plates (refer to picture situation 2). Illustration 09-53- 8: Unfilled situation, additional welding seams required Illustration 09-53- 9: Filled situation, ready to install reinforcing plate To assure a proper connection between the connection plate and the reinforcing plate, a filled situation must be given. For this reason it is possible, that the welding area must be filled with additional welding seams (1) before the reinforcing plate gets installed. IMPORTANT INFORMATION The steps mentioned above are not necessary in all cases but could be needed in some. In most cases a “filled” situation is given so the reinforcing plate can be installed straight away.  Grind the area after filling to ensure an even surface for the reinforcing plate. 1 2 1 2 PW Crane Repair work www.palfinger.com 13 Welding seams are ready (1) to install the reinforcing plate in order to get a perfect connection in between the connection plate and the reinforcing plate and also with the other parts affected by the reinforcing action. Illustration 09-53- 10: Welding seams ready to install reinforcing plate 5.2.2 Adjust and tack reinforcing plate As soon as the area is prepared properly, the reinforcing plate can be fitted and tacked onto the connection plate. Illustration 09-53- 11: Working area prepared for installation of reinforcing plate 1 Repair work PW Crane 14 www.palfinger.com The part number of the reinforcing plate is: HA22914. It can be ordered from the PALFINGER parts center. CAUTION The reinforcing plate must be clean and free of any contamination. It must fit flat and even on the reinforcing area. There must be no gap in between the plates. If it is not, it has to be adapted until it does fit properly. For this it could be necessary that the plate needs to be bent additionally. It also is possible, that it needs to be grinded in some areas in order to make it fit properly. Illustration 09-53- 12: Top side with welding bevel Illustration 09-53- 13: Bottom side 5.2.3 Tack weld reinforcing plate Align the plate and tack it. Start tacking on the left side (1, 2), continue on the right side (3, 4). Tack the reinforcing plate with 8 tack welds in total. Illustration 09-53- 14: Tack welds NOTE Make sure, the tack welds are placed as shown on the picture above. Otherwise there could be an incomplete fusion during the welding procedure. 1 2 3 4 5 7 6 8 PW Crane Repair work www.palfinger.com 15 5.2.4 Requirements of welding parameters and conditions This chapter explains basic settings, requirements and conditions which have to be obeyed during the welding work.

Between the turntable and the balance of the base, we have seen indications that a very localized area is not resisting the stress of normal use over the calculated lifetime of the crane. As a result, some bases have cracked after a few years. Whether a crack develops is largely dependent on applied working cycles and slewing angles at which the crane has been used. With the implementation of periodic visual inspections pursuant to instructions in the operator’s manual, an immediate failure of the affected component can be prevented. The performance of such periodic inspections can disclose the existence of a crack at its early, non-dangerous stage. PALFINGER has decided to initiate mandatory inspections for cracks on the affected component. As described below, cracks smaller than a certain size can be repaired. Bases containing larger cracks must be replaced. In addition, in order to improve the durability of all of these products, PALFINGER has decided to reinforce all existing bases in this product line. We hope this effort will show PALFINGER’s dedication to customer satisfaction. Any bases produced in PALFINGER’s factories in Europe after August 15, 2021 have already been modified and do not need reinforcement. 2 Affected Products Base S419G30SA and its updated design S419G30SB used on models PW 38001, PW 42001-SH, PW 38001EL, PW 50001-SH 3 Description 3.1 Location The affected area is located between the turntable and the balance. This area is accessible for an inspection without removing the crane, if the crane is mounted behind the cab. It might be necessary to remove the crane to carry out a repair or a reinforcement if the area is not sufficiently accessible (such as on installations behind the cab). Affected area The plate between the turntable and the balance has to bear high stresses during operation. The area in the oval is the localized area where cracks may develop and which needs to be reinforced using an additional plate. www.palfinger.com Page 2 / 6 PW R-NC-2103 Range Base Cracks (S419) 3.2 Visual inspection PALFINGER has decided to order a proactive visual inspection on all possibly affected cranes on the market. This must be carried out the following way: 1) Determine how many cranes are in your area of responsibility • Your cranes are set forth in the attached list of sold cranes, which has been prepared for you as an authorized PALFINGER Service Entity. • Understand that there is a higher priority on cranes with an “in-Service” date of 2018 and earlier and a lower priority on cranes sold 2019 and later. 2) Visit every customer for a visual inspection • Check higher priority cranes (2018 and older) first (refer to attached list of affected cranes) • Clean the affected area and check for the presence of a crack. The crack is visible when present and therefore a visual inspection is sufficient without additional methods. • To increase the visibility of a possible crack, extend the crane horizontally over the outrigger beam during this check (in the opposite direction of the balance; this is towards the rear of the truck in most cases). • The visual inspection can also be carried out by the end customer. In this case, your guidance is required to receive a clear result. Ensure that the “inspector” clearly understands the previous two bullet points. Above left: Crane extended and ready for inspection (with load in this case, but the empty fork is enough) Above: Inspection area, crane installed behind cab. Left (both pictures): Examples of cracks. The first picture shows an already grown crack, easily visible. The second one a “young” crack, which is safe at this stage but more difficult to recognize. Look carefully! www.palfinger.com Page 3 / 6 PW R-NC-2103 Range Base Cracks (S419) • If no crack is visible  Crane is safe to work. Arrange a workshop visit for a preventive repair within the next 6 months (refer to point 4.4). Ask the customer to carry out a visual inspection every month, as explained in the maintenance section of the operator’s manual. • If a crack is found  Prioritize the issue following point 4.1 – 4.3 depending on the size of the found crack  Arrange for and carry out a repair as soon as possible. If the total crack length is shorter than 3” and a repair is not immediately possible, a dye penetration test to clearly understand its dimension is additionally helpful (if this method is not clear, contact PALFINGER for guidance).  Follow point 4.1 – 4.3 based on the priority of the case 4 Repair procedure PALFINGER has designed a reinforcement plate, which must get installed on all cranes on the market, whether a crack is found or not. Repair plate The reinforcement plate HA22914 has been designed for repair and preventive reinforcement. The plate is available at the PALFINGER Parts Center (PPC). Be sure to order the needed quantity to cover the upcoming repairs. Based on the findings during the visual inspection (refer to point 3.2), the cranes must be prioritized for repair the following way: • Priority “A”: Crack in the critical zone. This is an unrepairable crack. Follow point 4.1. • Priority “B”: Crack longer than 3” but not touching the critical zone. Follow point 4.2. • Priority “C”: Crack 3” long or less. Follow point 4.3. • Priority “D”: No crack found. Follow point 4.4. Definition of the critical zone Remove the paint before evaluating a crack for its priority. A crack is in the critical zone if it reaches into the critical area (1) in either the right or the left side. This area (1) is 70 mm (2¾”) long on each side, measured on the welding seam from the outside towards the center. If there is a crack that reaches into the critical area, the base cannot be repaired anymore. This is then a priority “A” case. As long a crack is only present in the zone (2), a repair is possible. In uncertain cases, use a dye penetration test to clearly identify whether a crack touches the zone or not. 1 1 2 www.palfinger.com Page 4 / 6 PW R-NC-2103 Range Base Cracks (S419) 4.1 Priority “A”: Crack present in the critical zone • If a crack is found in the critical zone, a repair is not possible anymore, the base must be replaced. • PALFINGER calls this a priority “A” case. • Tell the customer to cease operation and to ground the crane. • Contact PALFINGER Service and order a new base (S419G30SB). When base arrives, check if it is a reinforced one, otherwise carry out the repair as explained in RA9-53 (most of bases will arrive reinforced from factory). • Organize a repair immediately with the customer and replace the base. • Document the case (refer to point 6) and claim it to PALFINGER (refer to point 7). 4.2 Priority “B”: Crack present longer than 3”, not touching the critical zone • If a crack is found over 3” long but does not touch the critical zone, a repair is possible. The crane is at a critical stage. • PALFINGER calls this a priority “B” case. • Tell the customer to cease operation and to ground the crane. • Inform PALFINGER Service about the presence of the crack and carry out the repair according to the attached repair guideline (RA9-53) and the general PALFINGER welding instruction. • Document the case (refer to point 6) and claim it to PALFINGER (refer to point 7). 4.3 Priority “C”: Crack present with 3” length or less • If a crack is found with a 3” length or less, a repair is possible. The crane is still safe to use. • Tell the customer that a short crack is present and that a repair is required within 3 weeks. • Inform the customer that the crane can still be used but the crack must be observed daily. If the crack grows over 3”, tell the customer to cease operation and to get in touch with PALFINGER. • Organize a repair within 3 weeks and carry out the repair according to the attached repair guideline (RA9-53) and the general PALFINGER welding instruction. • Document the case (refer to point 6) and claim it to PALFINGER (refer to point 7). 4.4 Priority “D”: No crack found • In this preferrable and most common case, no immediate action is needed. A reinforcement repair must be scheduled for no later than 6 months after the inspection. • Ask the customer to carry out a monthly visual inspection, as explained in the maintenance section of the operator’s manual. • Arrange a date for this job, but reserve time and space for higher priority cases until all machines under your responsibility are checked. (Based on time and availability, the repair can be carried out immediately). • Claim the repair to PALFINGER (refer to point 7). www.palfinger.com Page 5 / 6 PW R-NC-2103 Range Base Cracks (S419) 5 Measures on market • The visual inspection must be carried out as soon as possible, no later than the End of September 2021. • Depending on the result of this inspection, the described type of repair has to be carried out (refer to the notes under point 4). • If no crack is present, the reinforcement action has to be completed no later than the End of March 2022. • PALFINGER tracks these repairs using claim management software. It is therefore essential to get every case reported as soon as possible after carrying out the repair (using a claim, refer to point 7). • For cases without cracks found: If the crane is inspected but the repair is not carried out immediately, a claim reporting the visual inspection must be sent as well (refer to point 7). 6 Case documentation • It is very important for PALFINGER to get proper documentation of all inspections and repairs. • Therefore, the following things must be submitted with all claims (including visual inspections): o Overview picture of the truck (side view) o Picture of the area at inspection (with or without crack) o Picture of the crack before repair (if applicable) o Picture of the carried-out repair work before painting (if applicable) o Current Paltronic (PSY) file of the crane, taken at the time of the repair 7 Warranty handling A warranty claim can be made to PALFINGER using the standard procedure (claim management system) under the conditions described below. Two prefilled claims are already available for the repair under the equipment number, one for the inspection, one for the repair. Data must reflect the measurements taken during the inspection.
