Feature
Application：Handling and unloading of wood, stone and steel; laying of medium pipes for urban sewage; modeling operation of river and sea dam, etc. Feature: *The whole body is made of special wear-resistant manganese steel plate (high elasticity, wear resistance), with long service life *Adopt built-in safety valve to prevent the natural drop of the cylinder arm large capacity cylinder design, increase the grasping force of the equipment。 * The electronic control operating system adopts integrated design, simple installation control is more flexible and comfortable。 *There are single cylinder grab and double cylinder grab options, complete model size can be adapted to 5~35 tons of excavator, enhanced version of the structure design is more suitable for large load operation. *The hydraulic parts are imported, the cylinder balance valve does not relieve pressure, good tension synchronization, large displacement rotary motor holding imported SUN balance valve has good braking performance, high frequency heat treatment gear and rotary support more durable. *Oil cylinder rod diameter is 80mm and outer diameter is 170mm with Taiwan inlet balance valve, grasping force, do not drop the cylinder, good synchronization. *The assembly shaft of the wood cutter is made of 42 Cr material with high frequency heat treatment, which has more durable wear resistance and high wear strength. The structural design does not need the processing of butter road to help avoid the shaft breaking. *The rotary motor of the wood cutter adopts the American solar inlet balance valve, double overflow and double balance, the motor 600 displacement torque, very low failure rate, rotary support outer diameter 690mm, large tooth ring and small gear are 40 Cr plus high frequency heat treatment, continuous teeth are not broken. *The structural parts of the wood grab are all reinforced design, with Q355B manganese plate, which is more durable for high strength operation in the port. *The wood control system adopts streamlined design, the electric control wire harness and excavator with the same type of network design, resistant to large current impact, anti-aging, handle keys light and not tired hand, flexible and comfortable control, easy, the failure rate is very low, obvious advantages than similar products.
