QTZ31.5(TC3807)Tower crane is a kind of level-jib, trolley derricking, high level slewing, self-hoisting multi-purpose tower crane. The maximum working radius is 38m; The maximum lifting capacity is 3000kg
; The rated load moment is 315kN· M.
The crane can be used widely to middle and high residential house and high and long span industrial workshop.
The crane has independent and attached working mode. When it runs in independent mode, the maximum lifting height is 29m and in attached mode, the maximum lifting height is 70m.
The crane is convenient to install and disassemble; It applies hydraulic climbing equipment to increase or reduce crane body's height, so it can meet construction project's needs.
Operating mechanism: Hoisting mechanism is driven by tri-speed electromotor with high working speed and good speed-adjusting capability and high efficiency; Derricking mechanism using worm-wheel reducer
Can meet operating needs. Slewing mechanism that is driven by twi-speed electromotor; Make operation more stable and reliable.
Safety devices is integral sensitive and reliable. To ensure crane's normal operation, the weight limiter, moment limiter, lifting height limiter, trolley limiter and rotary limiter are set on crane, other safety
Evices such as rest platform, handrail, grip block and axle also are equipped.
Driver's cab that is alone and lateral is spacious comfort, safe and convenient to drive and has good angle of view.
