Description

B、Standard Equipments
1、Original packaging Japanese main pump: negative power + cross power control system, flow rate of 2×**0L/min. Energy-saving, with standby function and quick response.

2、Original packaging Japanese main valve: rotary priority valve, boom collecting valve, bucket pole collecting valve, bucket pole locking valve, straight walking valve, oil return recovery valve, breaking hammer service valve, external connected bucket collecting pipeline are assembled in the valve, which has complete functions.
3、Original packaging Japanese swing motor+ deceleration machine: With hydraulic time delay break, swing prevention valve, buffer starting valve. The impact and swing can be reduced, thus the positioning operation can be more accurate, and the life of components prolonged.
4、Japanese walking motor+ deceleration machine: With hydraulic time delay break, buffer starting valve, double walking speed automatic/manual switching, it is guaranteed that the moment and rotational speed can adjust to the ground working environment.
5、The operators can control the operations accurately. It is flexible, portable and reliable.
6、Slewing bearing: Equipped with large diameter slewing bearing, which can stand the impact, with high loading capacity, full-sealing, self-lubricating, waterproof, dustproof and pollution prevention.
7、Driving cab: Comfortable, spacious and safe. Well rounded and high strength driving cab with profiled bar framework, extremely low vibration and noise, and greatest operation comfort.
The effective space of the driving cab has been greatly increased and the sight has been broadened. The interior decoration is simple but beautiful. The silicone oil damping vibration absorber, which has an effective absorbing ability, has been used to further reduce the noise and thus make the driving more comfortable.
8、Air conditioner and sound: high power cooling and heating air conditioner and stereophony sound.
9、Electronic monitoring system: With electronic detecting and sound and light alarming.
C、The completely reinforced components ensure the best excavation ability
1、Crawler frame: The advanced X type crawler frame has reduced the deformation and distortion of the left-right beam, which can distribute the stress arising from loading and working load evenly along the whole length of the beam. The left-right longeron has adopted high quality steel plate which is pressed into a U longeron at onetime, and thus reduced the internal stress in welding and increased its service life.
2、Slewing platform: The general structure has adopted different beam structures, with the optimized methods to increase the general performance. Based on the design concept of uniform strength, the main beam has adopted the varying cross section “å·¥”structure.
3、Working device: The long boom and long bucket pole have adopted BS**0MC high strength steel plate, and optimized and reinforced design, which has greatly increased its strength and reliability.
