Abstract
A hydraulic jack having a piston, configured to lift at least a portion of a vehicle or trailer, and a housing, where the housing includes a high pressure fluid chamber configured to receive at least a portion of the piston, and where increasing fluid pressure within the high pressure chamber moves the piston further out of the housing. The hydraulic jack also includes a weight gauge attached to the housing and in fluid communication with the high pressure fluid chamber, wherein the weight gauge is configured and calibrated to measure and display the weight of the vehicle or trailer being lifted by the piston.
