Service Jacks

Description

Westward hydraulic service jacks are used for lifting part of a total vehicle (i.e., one
wheel). These jacks are equipped with a built-in by-pass device to prevent damage
to jack from overpumping. An internal safety valve prevents damage to jack from
overloading. Applications include automotive, truck, farm, industrial and construction.
Air models feature a powerful air motor, for effortless lifts of rated loads, conventional
foot pumping and handle pumping. These jacks are designed to meet applicable ANSI/
PALD Standards. RECOMMENDED AIR SUPPLY: 110-175 PSI at 7.8 CFM.
