ESCO Air Hydraulic Jack Models Compared

Pick an ESCO jack by the height of the lift point first, then by tonnage. The Mammut models run on compressed air with remote control; the 10809 is a hydraulic cylinder that connects to your pump.

ESCO Jack FAQ

Do I still need jack stands with the 10809?

The safety lock nut spins down to hold the load on steel threads, so the jack works as its own support stand. ESCO states it aids compliance with OSHA 29CFR1926.305.

How does a Mammut air jack lower the load?

Dual descent valves control lowering and the piston returns automatically. The 91003 and 91005 list an optional manual emergency pump.
