650T Crawler Crane With Long-term Use And Guaranteed Quality

SCC6500 Crawler Crane Technical Specifications

Safety devices

Main and auxiliary hook anti-over-release device

When the steel rope is released to the vicinity of the last three circles, the electrical control system automatically cuts off the hook-dropping action and issues an alarm through the buzzer and display.

Installation mode/working mode switch

In installation mode, the overwinding protection device, boom limiter, torque limiter, etc. are not functional to facilitate crane installation.

In working mode, all safety devices are functional.

Lifting arm limit device

When the main arm elevation angle is greater than 85° and the auxiliary arm elevation angle is greater than 75°, the corresponding limit switch will be activated, causing the buzzer to sound an alarm and the crane arm to automatically stop.

At this time, the luffing drum lifting operation does not work. However, the luffing drum lowering operation can be realized. When the main arm lowering angle is less than 30° and the auxiliary arm angle is less than 15°, the operation will be restricted. This protection function is automatically controlled by the torque limiter.

Crane boom anti-tilt device

The main boom and the superlift mast each have a pair of anti-tilt cylinders. When the boom tilts backward, the high pressure of the anti-tilt cylinder must be overcome. When the boom swings forward, the hydraulic system automatically replenishes high-pressure oil and tensions the boom to prevent the boom from vibrating and tilting backward during operation.

The jib fixed mast has an anti-tilt device, and the jib luffing mast has a pair of oil and gas cylinders to prevent the mast from tilting backward and tension the jib luffing wire rope.

After the jib reaches 75°, there will be a mechanical anti-tilt device to prevent it from tipping over.

Lifting mechanism brake

Each lifting brake adopts a spring-loaded normally closed disc brake, which has strong braking force, is maintenance-free, safe and reliable to use, and has a long service life.

Closed-circuit surveillance system

It can monitor the winding condition of wire ropes of each lifting mechanism, the status of super-lifting counterweight and the condition around the equipment.

Fault self-diagnosis system

The fault can be easily eliminated according to the fault code.

Black Box

The driver's operation and the equipment's operating parameters can be recorded, which is helpful for analyzing the cause of the accident.

Navigation Lights

Installed on top of boom.

Anemometer

Installed on the top of the boom, it monitors wind speed in real time and displays it on the monitor.

Electronic level

The tilt angle of the crane is displayed in real time on the monitor to protect the safe operation of the crane.
