This heavy-duty grabber product is a "dual power" invention patent product with internal combustion engine and 380V electric interchangeable operation, which is optimized, designed and refitted on the basis of the structure of the 70 ton mine shovel imported Liebherr technology .This "heavy-duty, high mobility" energy-saving and environmental protection bulk cargo handling and grabbing equipment uses high-power "national three" standard engine, 380V Siemens motor, and a full set of  the world's first "dual power" grab, which uses Schneider control system to drive and control two sets of Rexroth hydraulic power mechanisms and pilot hydraulic control.

. The machine is designed with a wide structural beam and a reinforced two-section main boom that can replace positive and negative difference. The maximum lifting weight is 25 tons and the maximum operating radius is 18 meters. Within the operation radius of 5 to 12M, it can be equipped with 5.0m3 clamshell grab or 2.5m3 plum shaped scrap grab.

This equipment is safe and energy-saving for electric operation, which can save 60% energy consumption compared with internal combustion engine drive; The hydraulic grab of different uses can be quickly replaced, and the multi-purpose function of one machine is realized. The overall features are as follows:

 equipped with "dual power" interworking and interlocking (patented technology) devices for alternating driving operation of internal combustion engine and 380V power;

Siemens motor is selected for electric operation, and a complete set of electrical components using Schneider control system are equipped with over current, overload, overheating and leakage protection devices;

equipped with step-down starting device;

automatic identification of phase sequence to prevent reverse rotation of oil pump;

power and oil cut-off self-locking and self-stop protective devices of hydraulic system;

there are multiple compound actions during operation to improve operation efficiency;

hydraulic system is installed with air-cooled radiator;

the gripper can rotate and change direction 360 degrees automatically;

when working in the upper control room, there is a dual-purpose air conditioning device;

cab lifting type;

Progressiveness of electric drive system:

the motor adopts YX3 series new generation high-efficiency and energy-saving motor, with efficiency up to 96%, power factor of 0.9, energy saving and power saving.

ats48c59q soft starter is used for motor starting control, which greatly simplifies the control circuit. ATS48 series soft start appliances have the functions of limited current, voltage regulation and torque regulation (the actual starting current is less than twice the rated current of the motor, which is quite ideal). The parameters such as starting voltage, current and torque can be set and adjusted according to different motors and loads. It has protection functions such as overheating, overload, overcurrent, undervoltage, overvoltage, short circuit, phase loss, phase imbalance, and all protection parameters are adjustable. The built-in display screen can realize real-time self diagnosis and alarm for motor startup operation parameters.

the engine adopts can bus control and J1939 communication protocol. The control circuit is simple and reliable.

the programmable monitor integrated with heshman (Weika) monitoring is adopted to realize automatic control of engine throttle. H (heavy load), s (standard) and l (light load) modes can be selected for engine throttle according to different working loads to save energy and fuel. The automatic idling function of the engine is realized with the pressure switch of the hydraulic system to save energy and fuel, and the throttle, maximum and idle throttle of each mode of the engine are adjustable. It can realize the display of engine parameters, hydraulic oil temperature and fuel level, fault self diagnosis and alarm functions, and each alarm point can be adjusted.

Adopt integrated maintenance free aviation technology electric slip ring.
