Hoisting mechanism adopts double speed double pulley winding motor to realize low speed on heavy load and high speed on light load, and max. speed can reach 100m/minute. Start and brake are steady, impact is small, and operation is convenient. Swing mechanism adopts domestically advanced frequency conversion timing project, which makes start and brake become steady and reliable.
Horizontal Arm Frame and Trolley Radius
The tower crane adopts horizontal arm frame, load is hung in hoisting trolley, and radius is realized through horizontal movement of trolley on arm frame. Compared with luffing jib tower crane, working is steady, installation is convenient, and radius application is wide, which can make hoisting performance be fully exerted, enlarge storing range of construction materials, and make disposal of general construction ichnography be convenient.
Safety devices are complete, and there are brakes fixed in each mechanism, which can ensure working safety. There are safety protecting devices like hoisting height restrictor, trolley radius restrictor, moment restrictor, hoisting weight restrictor and swing restrictor, etc. fixed in tower crane
