Operation:
1) Prepare the load with appropriate rigging to properly interface with the load hook at the end of the boom.
2) If necessary, adjust the position of the boom.
a. To raise the boom, move the pump handle back-and-forth.
b. To lower the boom, slowly turn the release handle (item no. 1.13 in FIGS, 4A and 4B)
counterclockwise until the boom begins to lower. To increase the lowering rate, turn the release
handle further counterclockwise. Close the release valve when the boom position is adequately
adjusted. To close the valve, turn the release handle clockwise until the connection is tight.
3) Attach the rigging to the load hook. The floor crane must be on a sound, level and dry surface. Before raising
the boom, be sure that the load hook is centered above the load. If the hook is not centered above the load,
the load might swing when the boom lifts it off of the ground.
NOTE: Rigging and all other load-engaging equipment must be added to the weight of the load to determine
the net weight of the load applied to the crane. The net weight must be less than or equal to the rated load of
the crane. As FIGS. 1B, 2B & 3B on p. 4, 6, & 8 indicate, rated load for each model of crane decreases when
the boom is extended.
4) Slowly raise the load until it is entirely suspended by the boom. Only raise the load a few inches above the
ground.
a. The load should not swing as it rises.
b. The crane should not tip or rock when the load is suspended.
c. If the crane is unstable when the load is suspended, do not use the crane to transport the load.
Return it to the ground and use another means to move it.
5) Carefully push the crane to transport the load. Do not leave the crane with a suspended load. Always lower
the boom until the load is entirely supported by the ground or other surface before leaving the crane.
Operating the manual hydraulic pump:
The floor crane is equipped with a hand-operated hydraulic pump that controls the up and down movement of
the load hook. With the lowering lever in the closed position (rotated clockwise until the connection is snug),
moving the pump handle back-and-forth causes the cylinder to extend. The cylinder attaches to the bottom of the
outer boom. As the cylinder extends, the booms pivot upwardly and this elevates the load hook.
To lower the booms, rotate the release lever counterclockwise until the booms begin to descend. The farther
the lever is rotated counterclockwise, the faster the booms lower. If you wish to change load elevation, but not
lower the load completely, simply close the release valve when the load is at the desired height by rotating the
release lever clockwise until the connection is snug.
To remove air from the hydraulic system:
1. Disconnect the cylinder from the crane by removing the clevis pins (see “Hydraulic cylinder” above left).
2. Lay the cylinder on a flat surface with the hose on top.
3. Loosen the hose fitting but do not disconnect the hose. Wrap a rag around the fitting.
4. Circulate oil to the cylinder by slowly moving the handle back and forth. Air and oil will sputter from the
fitting. When no more air is present, tighten the fitting and reconnect the cylinder to the crane.
