The Yale AJH-6100 SR is the largest jack in the Yale AJS / AJH aluminium range — 100 tonne capacity with the Safety Lock Nut Ring (SR) feature for positive mechanical locking under load. The lock nut allows the jack to mechanically support the load without continuous hydraulic pressure, which is essential for prolonged supports or safety-critical applications.
Heavy-duty aluminium jack with mechanical safety lock
For applications where the load must be held in position for extended periods — bridge bearing replacement, structural alignment, heavy lifts requiring inspection — relying on hydraulic pressure alone is unsafe. The Safety Lock Nut Ring on the AJH-6100 SR engages mechanically once the load is raised, transferring the holding force from the hydraulic system to a solid mechanical stop.
Key Features
- 100 tonne capacity: Largest jack in the Yale AJS / AJH aluminium range
- Safety Lock Nut Ring: Mechanical locking for extended supports
- Aluminium construction: Lower weight than equivalent steel jacks
