Stress calculations for a 50t tray lifting device
Calculations were required to determine the size and capabilities of
a lifting device to be used in the assembly of mining truck.
Specifically to lift the tray body onto the vehicle chassis.
The device is required to lift three different bodies onto their
chassis, these all have slightly different sizes and specifications. The
tray widths range from 160mm to the widest of 300mm
The device also has to be safe during lifting and not allow the tray to
slip off or move excessively.
The device also has to be operated by 1 person, and located into the
tray lifting point, the lifting points are really only accessible from
inside the tray due to the size and height of the tray. Therefore any
locking device has to be operated from the operators side.
