The interlocked and extendable hydraulic cylinder with technologies of cylinder and arm pin interlock, pentagonal slip deformation-proof and system detection allows free extension, insertion and extraction, and unlocking of each arm of the crane, satisfying requirement of high safety and energy saving under frequent working conditions. With advantages of reliable interlock, flexible movement and quick response, the product is widely used in all series of automobile, all-terrain and rough-terrain cranes.
Specialties:
Customized high-strength materials and ultra-thin cold drawing technology decreases 18% of the product weight.
Climbing structure with combination of pentagonal slide improves 42% of track stability.
Technology of overlength stroke anti-side guidance improves operation stability.
Technology of non-welding technology supported by clamp slide eliminates influence of welding.
Technology of cylinder valves connection in parallel ensures oil flow.
