make short work of toughest jobs. They are available in a broad range of lifting capacities for applications

in a wide variety of fields, including heavy-duty foundation work, this product is mainly designed for

engineering projects like subway, bridge, Petrochemical, power station, nuclear power construction



Advantages:


1. Rexroth swing reducer

Planetary reducer, controllable constant-close disc brake, high reliability, easy for maintenance.


2. Rexroth gear reducer

Built-in gear reducer with small turning radius, high maneuverability and reliability


3. Imported logic valve

Logic valve can realize precise logical control and simplify the system, easy for maintenance.


4. Imported PAT load moment indicator

LMI can detect working conditions of crawler crane, having the function of protection.


Safe and comfortable ergonomic design


1. Adjustable boom backstop device

When the boom is elevation upwards, the detector board approaches to detecting switch; when reaching

maximum elevating angle, the detector board impacts detecting switch and the switch is off, then warning
