Master Controller work as safety device for controlling the movement of crane. This controller is suitable for reversing drives like winches, rolling mills, cranes, hoists, etc. Robust construction, automatically reset system and power resistors are qualities of offered controller. Moreover to this, compact and space saving design of the offered Master Controller ensure ease usage and installation. Moreover to this, the offered controller is made obtainable in a wide range of specifications.
Master controller is hand-operated equipment, incorporated with many control elements. It assists in the task of driving as well as braking. Also, it is useful in controlling the secondary function of traction rail mediums. Master controller is provided with reliable & high-precision response and needs less maintenance. Its standard and compact design enables for simple connection with the circuit. The connection can be made via the bayonet connector as well as SUB-D connector. The strapping design it boasts of makes it capable to resist the vibration occurred during the work. Due to low friction of moving parts, the service life of master controller can be enhanced. Mechanical interlocking is manageable with the brake control handle. This shock-resistant controller ensures total safety and high operational efficiency.
