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.
