A telescoping stabilization strut system generally comprising a fixturing pin system with accidental or inadvertent operation protection for providing stability and support between a bearing surface such as a ground surface and a load such as a vehicle, an aircraft, a machine, or a structure.

A roller system including a top roller, a middle roller, a split lower roller and a split workbench roller configured for a pump jack arranged for travelling up and down a pole, wherein the top roller includes flanges at both ends of the roller; wherein the split lower roller includes a pair of facing lower rollers, each of the pair of facing lower rollers having an outward tapered flange; and wherein the split workbench roller includes a pair of facing workbench rollers, each of the pair of facing workbench rollers having an outward tapered flange.

An axle stand for use with a trailer including a rotatable wheel hub mounted to a distal end of an axle, the wheel hub having a plurality of wheel studs, the axle stand including: a lower component having feet configured to contact soil; an upper component assembled in a sliding fit with the lower component to provide an adjustable height, the upper component having an upper end and a lower end, wherein the upper end defines a saddle including a cutout sized and shaped to receive a central portion of the wheel hub, the saddle further including mounting holes which correspond to a bolt pattern of the wheel studs; and a locking plate configured to be locked to the upper component to prevent access to at least some of the wheel studs.

A floor jack locking assembly is presented. The locking assembly may include a locking pin used to mechanically lock out the jack at a specified lift height. The locking assembly may avoid the hydraulic lift cylinder being the only stabilizing component of the jack when supporting a significant load. The locking pin may be coupled to lifting link arms, avoiding the need to have the locking pin inserted into or through the lifting arm of the jack.

A dump trailer support assembly for supporting a belly dump trailer when the belly dump trailer is not coupled to a tractor includes a box for positioning on a support surface beneath a belly dump trailer. A shaft is slidably integrated into the box such that the shaft can be slid upwardly or downwardly in the box. A support is coupled to the shaft for supporting a bottom of the belly dump trailer when the belly dump trailer is not attached to a tractor. Additionally, the support is comprised of a magnetized material to magnetically engage the bottom of the belly dump trailer and inhibit the belly dump trailer from sliding on the support.

A safety link for linking a high-lift jack to a vehicle may include an upper bracket and a lower bracket. The upper bracket may include one or more slots for securing the link to a vehicle shackle tab. The lower bracket may include one or more slots for securing the link to a jack.

A multi-lift point elevator includes a lifting frame for elevating a plane. The lifting frame includes lift stanchions with telescoping tubes controlled by bias connectors extending into the telescoping tubes from leaf springs connected to the lifting frame. The leaf springs are activated by a connector extension, which urges the leaf springs away from the lift stanchions to release the bias connectors from the telescoping tubes to cause the telescoping tubes to extend or retract as a jack elevates or lowers the plane.
