Product Description

Description:
Balancers contain a stationary ball screw. The ball screw is held in position by two hex head bolts (through the end cap and end cover). Two
pins in the end cover engage notches on the end of the ball screw to prevent it from rotating. The reel assembly, consisting of reel, ball nut and
thrust bearing, rides on the ball screw. The piston contacts the thrust bearing and travels back and forth with the reel assembly. The piston does
not rotate.
Compressed air powers the balancer. It is controlled by an external control package. Air enters or leaves the piston chamber through a single
hole in the end cap. This compressed air causes the piston to move laterally. The piston pushes against the thrust bearing causing the reel to
move laterally along the ball screw and winds up the wire rope. The load or hook travels down when the air is exhausted from the
piston chamber through the control package to atmosphere.
The Balancer achieves maximum capacity at 100 psi, as the line pressure reduces so will the operating capacity of the Balancer. For every one
psi reduction in air pressure there is a 1% reduction in overall capacity.
If the balancer has no load attached, it may be necessary to pull down on the load hook to lower.
The 500 lb. (227 kg) balancer is designed to hang at a 3 degree angle with the controls end lower than the end cover.
