Locating on the counter jib, the L cabinet(Frequency Control) control the hoist mechanism, which can stable start and stop.

The L Panel for LVF controls the hoisting mechanism, which is located on the counter-jib.

This kind of hoisting mechanism adopt frequency control as the standard equipment, which can realize entirely stepless speed changing, stably start and stop, minor mechanical and electrical concussion which can prolong the using life of the steel structure and transmission mechanism, outstanding security, high reliability, low maintenance cost and obvious energy saving. Further more, bigger cable winders rope capacity and faster working speed could meet the special height request for the project.

The electrical control system has been optimized on the base of POTAIN technology. So it has many advantages, such as compact structure, reasonable layout, reliable quality and low maintenance cost etc. All electrical parts are from famous supplier at home and abroad, such as SCHNEIDER Contactor and Japanese YASKAWA Rrequency Converters etc.

We can match the components of Electric Control Panel according to customers’ specially requirement. Our Panel strictly follows international universal standard, thus it can replace customers’ same panel. These Panels can control 450-16000 KNM tower crane.
