High-load locking cylinder with precision position retention capability, featuring dual safety mechanisms: mechanical lock and pneumatic pressure holding. The hardened stainless steel locking pin engages within 0.5° rotation angle, achieving ISO 15552 standard Class 4 positioning accuracy. Designed for vertical applications requiring emergency stop functionality.
- Press machine safety interlocks
- Automotive welding fixture position locking
- Elevated platform emergency braking systems
- Die-casting mold securement during cooling
- Heavy-load robotic arm end effector positioning
Installation requirements:
Requires minimum 0.3MPa air pressure for lock release. For vertical mounting,
install manual override lever (optional accessory AT-LV125) within 1m reach.
Lubricate guide bushings every 500km of cumulative stroke movement.
Safety notice:
Lock engagement time ≤0.8s after signal input. Never exceed 1,200mm/s piston speed
during locking phase. Always install mechanical stopper as secondary safety measure.
