Compact light weight design. Rolls directly into truck with no assembly on site. Just bolt together the truss, and add a couple of spigots and you are done.

One Servo Motor does the work of 6 Chain Hoist. The use of a
single motor insures synchronization of lift. Simplifies and
speedsup the programming of moves.

•Drums can be repositioned to match
LED Header Pick Up Points.
•Programmable moves from Slow
& Graceful to Super Fast.
