A method and apparatus for moving a load. The apparatus is a floor jack that capable of reaching the load in a minimum amount of pumping by the operator. The lift reaches the load in a shorter amount of time so that the load can be moved quicker.
A method and apparatus for moving a load. The apparatus is a bottle jack that capable of reaching the load in a minimum amount of pumping by the operator. The lift reaches the load in a shorter amount of time so that the load can be moved quicker. The volume of the pumping chamber can be between about to {fraction (1/7)} the volume of the piston rod chamber.
A sash locator for locating a casement window sash relative to a sash arm, includes an abutment structure disposed at a selected disposition relative to the sash arm such that positioning the sash proximate the sash arm with a selected portion of the sash abutting the abutment structure disposes the sash relative to the sash arm in a desired disposition for affixing the sash to the sash arm. A method of sash location relative to a sash arm is also included.
A portable puller tool for track end connectors having a base with a fluid cylinder therein for mounting a ram for extension outwardly of the base, an arm extended outwardly from the base to locate an end thereof at a distance from the base to engage an end connector and a pair of pusher members connected to the ram for engagement with a pair of track pad shafts whereby extension of the ram relative to the base causes the base and arm end to move away from the track and pull the track end connector off said track pad shafts.
A preferred constant horsepower, variable volume hydraulic pump (10) includes a wobble plate (22) coupled with interior end of the pump drive shaft (18) configured for sequentially stroking a plurality of pistons (28,30) received in respective cylinders (42,44) included as part of a nonrotatable barrel (24). A shifting mechanism (74) axially shifts the barrel (24) in accordance with the output pressure in order to change the stroke length of the pistons (28,30) in the cylinders (42,44) and thereby change the flow rate through the pump (10). The shifting mechanism (74) is configured to lower the flow rate as the output pressure increases in order to maintain a constant horsepower demand for maximizing the flow volume for a given horsepower.
