HOIST MOUNTING INSTRUCTIONS (VC 520 NON-SUBFRAME ONLY)
Refer to drawings 520601 or 520603 (on the preceding pages).
CAUTION
If the distance between the center of the rear axle and the rear hinge assembly exceeds 38", additional
reinforcement of the truck frame is necessary.
A. Mark the location for the rear hinge. Ideally this location will be immediately behind a truck cross member
approximately 34" behind the center of the rear axle on a single axle truck.
B. Cut a 90° slot in each side of the frame as shown in Figure 2.
C. Position the angle iron frame of the rear hinge assembly in the truck frame cut outs. Make sure the rear hinge
assembly is properly positioned on the truck frame. Weld all around truck frame rear hinge assembly joint (both
sides).

D. Locate the hoist on the truck frame, making sure to center and square the hoist to the truck frame. The VC
Hoist is designed to rest on the truck frame. A section of the hoist extends below the truck frame level.
Therefore, the hoist may have to be moved slightly forward or backward to avoid frame crossmembers. The
distance between the rear hinge assembly center and the lower pivot is referred to as the "M" dimension. The
table on drawing 520603 provides the dump angles associated with various "M" dimensions.
Note: Moving the hoist along the truck frame will affect the hoist's performance. A forward movement (toward
cab) decreases dump angle and increases capacity. A backward movement increases dump angle and
decreases capacity (see dwg. 520601).
