Durable Mobile Hydraulic Crawler Crane QUY50 , Tracked Lattice Boom Crawler Cranes

Principle:

A crane is a type of machine, generally equipped with a hoist, wire ropes or chains, and sheaves, that can

be used both to lift and lower materials and to move them horizontally. QUY50 crawler crane is an

independent-developed hydraulic drive, full swing and lattice boom crawler crane, absorbing foreign

advanced technology and combining present domestic situations. It features easy and maneuverable

control, smooth vehicle travelling.

Scope of Application:

Crawler crane is mainly used for lifting heavy things and transporting them to other places. crawler cranesmake 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

signal is sent out and the elevating motion stops so as to avoid dangerous accidents.

2. Hydraulic-controlled winch ratchet lock device

The automatic-controlled winch ratchet lock device ensures safe and reliable boom orientation, easy and

comfortable operation.

3. Comfortable Operator’s Cab

Adjustable damping chair can change seat angle; air-conditioner and roller blinds build comfortable

operation environment

4. It embodies the design idea of putting people first. The brand-new design for whole vehicle layout,

outline, drive’s cab, operator’s cab and control components by using 3 dimensional styling technology

and ergonomic principle makes the operator more comfortable
