Detailed Introduction
The under part
Travel drive
The travel system has two speeds; it has strong traction and can achieve 70% load-carrying steering; each travel reducer is driven independently, which can flexibly achieve forward, backward or on-the-spot steering.
Travel brake
The travel brake is a normally closed type placed inside the reducer (i.e. it is in the braking state when the travel handle is not operated). It can automatically compensate and does not require adjustment. When the travel handle is operated, the brake is released and travel is achieved.
Track Shoes
The left and right crawler walking devices have a total of 136 track shoes, each with a width of 1500mm. The tension of the track shoes can be adjusted by hydraulic jacks, and the position of the gaskets can be adjusted to achieve the ideal tension.
Base
High-strength welded frame structure; hydraulic cylinder drives the power pin to connect with the crawler frame, which makes installation and disassembly very convenient and easy.
Traveling speed
The variable speed motor can achieve two speeds, and can achieve infinite speed change in each speed, high speed: 0~1.0km/h, low speed 0~0.55km/h, to ensure the smooth operation of the equipment and realize walking.
Operating equipment
All operating device pipes are made of high-strength steel pipes, plates are made of high-strength steel plates, and luffing supports are also made of high-strength steel pipes; pulley materials: all pulleys on the boom are rolled and welded pulleys, and all pulleys on the hook are rolled and welded pulleys;
Boom
The boom is a space truss structure with a uniform cross section in the middle and variable cross sections at both ends. The steel pipes are welded, and the top and root of the boom are reinforced with steel plates, which is more conducive to load transmission.
The length of the main boom is between the basic boom (24m) and the maximum length (108m).
Composition:
Lower boom 12m×1, transition boom 10.5m×1, connecting section 1.5m×1, intermediate boom 6m×2, intermediate boom 12m×6.
