Product Description

750 tons New Zoomlion crawler crane QUY750 
The electro-hydraulic proportional control and outstanding inching performance can meet the precision lifting function.
Multiple security protection of the three-color lamp sound-light alarm, walking alarm and torque limiter.
Swing mechanism adopts independent closed-type system, imported swing pump and adjustable eccentric swing reducer, which guarantee the smooth swing operation.
Self-assembly and disassembly function is equipped, which can reduce assembly and disassembly time and mounting cost arised from auxiliary crane.
Working with main hook under operation with fixed jib (S-2) and working with auxiliary hook under operation with fixed jib (SF-2) are available. With fixed jib installed, the switchover between main hook and auxiliary hook can be realized through the switchover of operation mode in the monitor, and thus the time for boom dismantling and replacement can be saved.
Excellent anti-rollover stability - It still has a 35% safety margin at rated load.
The electrical system uses flexible cables featuring corrosion, oil stain and UV resistance and electrical connectors featuring superior waterproof performance to prolong its service life.
