Each of the control switches corresponds to an individual drum. The left switch controls the hook. The center switch controls
the boom height. The front switch controls the front drum which swings the boom to the left. The counterbalance (55 gallen
gray drum) is used to return the boom to its neutral position.
The operation of the unit is an acquired skill. I do not allow myself to touch the hook or loading ring when picking up the
palleted materials. Instead, I use all three drums to manipulate the hook to the correct position. Once you get the hang
of it, the hoist functions like an extension of your hand.
