How To Control The Electric Control Handle On The Excavator Log Grapple

Electric control of the excavator log grapple must include the center swing joint, solenoid seat and two solenoid valves,Both solenoid valves are mounted at the top of the solenoid seat,And the solenoid valve, solenoid seat and center rotary joint are installed in the middle of the rotary support of the jack.The central rotary joint is located below the solenoid seat, and the side of the solenoid seat.A hydraulic cylinder is provided below the central rotary joint.The oil inlet of the central rotary joint is connected to the standby oil circuit through the solenoid valve.The utility model does not change the hydraulic system of the original equipment.There is no need to install two hydraulic valves, foot valves and four hydraulic pipes.Easy modification and reduced cost.The use of two-hand handle electric control, more convenient than the use of foot, higher efficiency, integrated solenoid valve controller integrated, small space, low failure rate.

The excavator log grapple is an instrument designed and developed to grab wood.The excavator log grapple is divided into the mechanical wood and rotary wood.Mechanical excavator log grapple  can be used without modifying the excavator pipeline and hydraulic system (low cost).The rotary grab requires refit the excavator line and hydraulic system to achieve a 360 degree rotation.

At present, the excavator wood grab on the market is generally just a simple wood grab.Modification in the use of the equipment need to install two hydraulic valves, foot valves and four hydraulic pipes.After taking oil from the standby oil circuit of the modified equipment, two hydraulic valves are divided into two ways for the motor and oil cylinder through four oil pipes.The hydraulic system of the original equipment is changed more, and the installation is troublesome.The modified equipment is prone to human failure due to modification or the hydraulic system of new equipment is warranty due to modification; after modification, two foot control valve is required to control the grip.
