Equipment Adavntage
< Technical Features
1. Compact design, Safe and reliable performance
Reasonable design and controllable production process ensure the machining accuracy and dimensional accuracy of various parts, so as to ensure the parts performance.
2. High alignment accuracy and wide application range
The core working parts are selected from international famous brands and processed by structural parts CNC machining center, to achieve high alignment accuracy of the alignment components.
3. Expanded application
By replacing the expansion blocks, the adapter can meet the needs of pipeline size changing in a certain range, expand the application range of the adapter and realize one machine with multiple functions.
4. Clean, efficient, environmental protection, strong climbing ability and strong passing ability
Compressed air is used as power, clean, efficient and meets the requirements of HSE construction management.
World famous brand pneumatic motor and compact structure design, save energy, and has strong climbing capacity (＞20°) and strong passing capacity (30 times D)
5. Fast adjustment, easy maintainance
When need to adapt to different wall thicknesses, the equipment can be quickly, conveniently and accurately adjusted in place to provide high work efficiency
6. DNQ16'' and above size pneumatic clamp has self-propelled system
Adjustable walking speed, lower air consumption and better climbing performance.
Double side expansion braking of cylinder is adopted for braking, with excellent braking force and braking speed.
The traveling system and the braking system form a gas path interlock to improve the flexibility and safety of ramp operation.
7. Limit device added to the expansion system
Fundamentally put an end to supporting the dead center. In previous cases, pipe jamming accidents have never occurred
