Safety Precautions
Cross Frame Reinforcement
Before welding and installing any suspension component parts to the
trailer frame requiring the raising of the vehicle, make sure that the vehicle
is properly supported on lift stands of sufficient capacity. Follow the vehicle
manufacturer’s recommendations for lifting and supporting the unit.
Cross frame reinforcement recommended on hangers to assure full load
carrying capacity of axle suspension. Standard 3” structural channel is
suggested as reinforcement members. Weld as indicated.
Do not lift with or place supports under any part of the suspension system
unless specifically directed to do so during these installation steps.
!
Front Hanger
CAUTION
Never rely on jacks alone to support the vehicle. A vehicle
that is not securely supported may fall and cause severe
injuries or death.
Safety glasses should be worn at all times when assembling
or disassembling axles and their components. Failure to
comply may result in serious eye injury.
General Guidelines for Hanger Welding
1.
It is recommended that the hangers be centered on the frame rails.
2.
Starting and stopping at the corners of the hangers is NOT
recommended.
3.
Craters/ends of welds should be back-filled to prevent cracking.
4.
The weld should be inspected for cracks, undercut, poor porosity,
and inadequate penetration that may cause the hanger to fail.
