Description

Westward hydraulic Quick Lifting jacks are used for lifting part of a total vehicle (i.e., one wheel).  Jacks are equipped 

with a built-in by-pass device to prevent damage to jack from overextension.  An internal safety valve prevents 

damage to jack from overloading.  Applications include automotive, truck, farm, industrial and construction.  These 

jacks are designed to meet applicable ASME/ANSI PALD Standard.
