The tower crane is advantageous for construction.
(1) It has many working modes with largest application range. Groundwork is poured on the ground without under frame, and tower crane is fixed directly on the groundwork.
(2) It adopts hydraulic hoisting system to increase or reduce standard sections, which makes height of tower crane rise or fall according to height of construction to adapt construction of
different buildings.
(3) Working speed is high, timing performance is good, and working efficiency is high.
(4) Safety devices are complete, and there are brakes fixed in each mechanism, which can ensure working safety.
(5) Driving room is set separately on side with good field of vision and large working space, which create better working environment for operator.
