Description
Polar Focus Motor Zbeam with pulley options to fit Stagemaker SM10 bodies of 1 ton chain hoists, for up to 2 ton loads.
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″ 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.
Only one motor is required to control pan and tilt per cluster, resulting in significant savings. The vertical position of each cluster can be controlled by a single motor control pendant or pickle. Since tilt is not controlled by synchronous operation of two hoists, no motor control package is required. This results in additional savings.
Pan angle is adjusted by turning the suspended speaker load relative to the Motor Zbeam. The pretensioned 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. Below is a link to a Polar Focus video showing a Motor Zbeam with an EAW cluster.
Even the largest line arrays can have full pan control with a Motor Zbeam.
See the Polar Focus PY1 Quick Disconnect Fitting for solutions that allow an easy connection between the line array frame and line array accessories, for infinite adjustability with our Motor Zbeam and associated products. This product is compatible with any Polar Focus product with a part code beginning with ‘PY0’ or ‘PY1’, allowing simple system design. We offer a full line of structural attachment accessories for roofs, walls, poles, crank towers, lighting truss and motor adapters.
