A crank mechanism incorporates a ratchet driver post coupled with a conventional, manually operated crank handle. The post is configured, possibly relying upon biasing members, pins, or sleeves, to ensure the ratchet driver may be operated without unwanted rotation of the handle. A number of iterations provide for multiple positions of the handle itself so as to speed up the early stages of jack actuation and then allow for repositioning in the later stages to maximize the user's leverage. Further still, a disengagement driver gear can be employed, and the invention may incorporate any combination of these features to improve operation and extension/retraction of the jack.

A suspension system for a land vehicle is provided with at least one actuator connected to a chassis and an axle of a land vehicle spaced apart from a pivotal connection of the axle. A suspension circuit is in cooperation with the at least one actuator. A controller is in operable communication with the suspension circuit and is programmed to receive input indicative of a travel speed of the land vehicle. The suspension circuit is closed at a low speed travel range to permit the axle to pivot in response to variations in an underlying support surface. The suspension circuit is opened to permit selective actuation of the at least one actuator at a higher speed travel range in response to variations in the underlying support surface.

Method and apparatus for an adapter designed to be placed onto the upper portion of the saddle of a floor jack or other related lifting device. The adapter has two forwardly extending lifting arms thereon which lifting arms can be placed underneath a wheel so as to lift the wheel of the vehicle or related device such as a motorcycle. The adapter is designed to have left and right, angle iron frame members such that the inwardly extending flanges of the angel iron frame members receive and cradle the saddle of the floor jack therein. The adapter has front and rear locking rods which are used to lock the adapter onto the upper surface of the saddle of the floor jack. A plurality of apertures are provided in the adapter for adjusting the width of the locking rods so that the adapter can be used with a variety of sizes of saddles of the floor jack.

The invention relates to a tool tray that holds tools and parts that is attached to the sides of the aerial lift and can be moved around the sides of the lift when necessary. The aerial lift mechanic can easily mount this tool tray on either sides of the lift to make it easily accessible to utilize tools to complete the project. On one hand, the Aerial Lift Tool Tray can be used as a dual function component that allows the functionality of the tool tray to be temporarily mounted on various sides of the lift; on the other hand, the Aerial Lift Tool Tray can allow the lift mechanic to keep their tools together in one place so that the completion of the project/job can be quicker, more efficient, and without interruption of locating tools that are not together in one place.

The scissor jack cover may be a protective cover for an individual scissor jack. The individual scissor jack may be coupled to the underside of a vehicle. While residing inside of a cavity within the scissor jack cover, the individual scissor jack may be protected from water, road salt, dirt, and other contaminants which may make the individual scissor jack difficult to operate. The vehicle may employ a plurality of scissor jacks to level and stabilize the vehicle when the vehicle is stationary. Multiple instances of the scissor jack cover may be deployed to protect each of the plurality of scissor jacks dispersed beneath the vehicle. As a non-limiting example, the vehicle may be a toy hauler trailer, a recreational vehicle, a travel trailer, a motor home, or other conveyance.

A method controls the movement of a boom, wherein the boom is moved by a plurality of hydraulic drives. Each hydraulic drive is fed with a hydraulic medium, the pressure and/or volume flow of which is adjustable. The method predefines a desired direction of movement and a desired speed of a boom tip; predictively calculates a pressure and/or a volume flow required for each of the hydraulic drives that are required for the desired direction of movement and desired speed; subsequently generates a supply pressure depending on the predictively calculated pressures and/or subsequently generating a supply volume flow as a function of the predictively calculated volume flows; and subsequently feeds the hydraulic drives required for the desired direction of movement and desired speed with the hydraulic medium having a respective feed pressure and/or a respective feed volume flow such that the boom tip moves in the desired direction of movement at the desired speed.

A leveling system for a lift device includes an axle, a pin, a cradle, and a chassis. The axle is configured to rotatably couple with one or more tractive elements. The pin extends through a bore of the axle. The cradle is pivotally coupled with the pin. The chassis is pivotally coupled with the pin and includes a first actuator and a second actuator. The first actuator and the second actuator each include a body and a rod configured to extend relative to the body. The rods of the first actuator and the second actuator are configured to be extended to engage corresponding surfaces on opposite sides of the cradle. The cradle and the chassis are configured to rock in unison a limited angular amount relative to the axle.
