DZJ-90 pile driving hammer Shock-proof motor High Temperature
Features
Shock-proof motor
Shock-proof motor can work under high temperature up to 95, permit short-time overloading and has high starting torque. Wedge-shaped belt of high-strength is adopted.
Bearing
The bearings required will receive impact load, radial acceleration, high limit speed and other additional load. Use German FAG bearing to increase load capacity to more than 18% and prolong liftspan to more than 70%.
Production technology
Premier welding process complies with national standard and is inspected by Ultrasonic-wave. Bottom of the gear box is reinforced to minimize the possibility of damage.
Noise-proof design
Install rubber pad on top and bottom of the springs to realize buffer action and absorb noise. Steel pad is added on spring bottom to reduce noise.
Bearing ring design
Specially-designed bearing ring with three layers to withstand intense vibration and avoid cracking during operation, much more superior than traditional embedded design.
Oil precipitation design
Foreign matters may fall into the box accidentally, and oil precipitation system is designed to prevent these matters and oil stain from doing harm to gear and bearing.
