Polar Focus Motor Zbeam with custom pulley options to fit CM bodies. Chain samples are required for design.
Polar Focus Motor Zbeam allows for a single electric chain hoist to support a speaker load (line array, or conventional boxes) with control over pan and tilt. This system has a 2:1 mechanical advantage using a 10 inch diameter chain-pulley. Thus a one-ton chain hoist can be used for two tons of loudspeaker load. The pan angle of the speaker load is supported by a Zbeam axle for easy aiming.
Pan angle is adjusted by turning the suspended speaker load relative to the Motor Zbeam. The pre-tensioned friction bearing holds the pan angle after you stop applying torque. The most popular suspended speaker loads are line arrays, with tilt controlled by a Spine Frame Adapter™. Other speaker cluster configurations are available.
Even the largest line arrays can have full pan control with a Motor Zbeam. Polar Focus Motor Zbeam Single Hoist Steering for CM Hoists.
