SEVENCRANE Spider Crane Product Features

It is like discussing and discussing to create quality, and it is like polishing to create brilliance. SEVENCRANE Technology unremittingly pursues product quality. Adhere to precision manufacturing, innovative development, and the success of our customers is our success.

SEVENCRANE invention patented two-speed winch

At single magnification, the hook has two speeds, the lifting speed of the 3-ton truck is 21.4m/min and 40.8m/min, and the hoisting rope capacity reaches 100 meters. It is especially suitable for transporting objects in high-rise buildings. The lifting speed of the 8-ton truck is 50m/min or 85m/min, and the hoisting rope capacity reaches 150 meters.

SEVENCRANE invention patented two-speed winch

At single magnification, the hook has two speeds, the lifting speed of the 3-ton truck is 21.4m/min and 40.8m/min, and the hoisting rope capacity is up to 100 meters. It is especially suitable for transporting objects in high-rise buildings. The lifting speed of the 8-ton truck is 50m/min or 85m/min, and the hoisting rope capacity reaches 150 meters.

SEVENCRANE patented double cylinder

The boom of spider cranes adopts double oil boom and unique 5-section arm design, which can be extended and shortened. Under the same lifting weight, the volume is smaller (length 2.9 meters). You can take a 3-ton elevator to go upstairs, and the boom can expand and contract to a certain extent with the load.

Simultaneous multi-action operations

The boom control realizes compound movements and improves work efficiency. The boom and hoisting operations can rise and fall, telescope, and hoist and rotate at the same time.

Crane leg walking interlocking

Only after the boom is reset can the outriggers be operated and walked to avoid the risk of rollover caused by changes in the crane’s center of gravity.

SEVENCRANE patented outrigger sensor

Each outrigger is equipped with a grounding sensor. When the outrigger leaves the ground and is in danger, the machine will wake up and alarm, and stop working to prevent the vehicle from rolling over.

The boom is equipped with a moment limiter, and each length displays a corresponding limited load to ensure that the crane operates under a safe lifting capacity. Together with the moment limiter, it forms a double insurance, which can prevent rollover accidents and prevent overloading from damaging the boom.
