miniature crawler crane, powered by Yangma diesel engine, is A fully proportional intelligent spider crane with remote control. The power and hydraulic system are all made of original parts from Japan, making the power output efficient. Danfoss proportional valve is adopted in the system, can according to actual needs, to realize the stepless speed regulating, leg have a key leveling function, eliminating the tedious leg leveling operation, work more efficient, hanging arm, leg and walking to realize self-locking interlock, and install a torque control, makes the equipment operation more secure, especially equipped with step pioneering double speed winding, fast speed, high efficiency.

Product features

Adopt double speed winch; Single rate, hook with double speed, speed is 24m/min and 48m/min, winch drum capacity hit 100 meters, especially suitable for high-rise buildings of the object transport.

The lifting arm adopts double oil cylinder, unique design of 5 pieces arm, long extension, short contraction. Under the same lifting weight, the crane volume is smaller (the length of spider crane  is 2.9 meters), and it can take the elevator with a load of 3 tons to go upstairs, and it can make the boom to a certain extent of load expansion.

Sensor of outrigger on the ground
Each leg is equipped with grounding sensor, when the leg off the ground danger, the machine alarm, stop working.Ensure that the machine will not overturn.
The crane arm is equipped with moment limiter, each length shows the corresponding limit of load, to ensure that the crane works under the safe lifting weight, and with the moment limiter together to form a double insurance, It can prevent the rollover accident and prevent overload and damage to the boom.

Interlock system
After the lifting arm is reset, the supporting leg and travel can be operated to protect the safety of the crane.

The outrigger is fixed from multiple angles, and the outrigger can be adjusted and fixed according to the construction environment in the face of different narrow working environment.
Legs can be operated independently according to the surrounding environment, or 4 legs can be controlled by remote control at the same time to achieve one-button leveling. Beginners can also operate legs easily, so that the car body is always in a level state.

380V electric power and gasoline engine (diesel engine) dual power. In places where the engine cannot be used, it can be dragged by wire for operation (especially in areas where gasoline and diesel are strictly controlled), and it can also be equipped with battery pure electric spider crane.
