For shop crane and engine hoist applications, this 4-ton long jack provides a lifting range from 19-7/8 to 34-3/4" (504.8 to 882.6 mm). It utilizes a metered control release valve to lower the boom at a controlled rate of speed, while an internal load-limiting device protects the crane and user from overloads.
