A support assembly comprises a bracket, a blocking member, and a spring. The blocking member is adapted to slidingly move within a through opening of a support member. The blocking member is adapted to be selectively moved from a supporting position to a non-supporting position. The spring is adapted to bias the blocking member towards the non-supporting position. In certain embodiments, the bracket is adapted to retain the blocking member at least partially within the through opening when the bracket is mounted to a hoist. In certain embodiments, the blocking member comprises a handle comprising a pin axially aligned within a compression spring and the bracket comprises a notch adapted to receive the handle.

A hydraulic system includes a pump in communication with a fluid reservoir and powered by a motor. A pressure compensator is adapted to adjust a position of a variable displacement mechanism of the pump. A load sensing line is adapted to communicate a highest load sensing pressure from a plurality of valves to the pressure compensator. The pressure compensator adjusts the variable displacement mechanism of the pump based on the highest load sensing pressure for maintaining a constant pressure drop across one or more work ports in each of the plurality of valves. The plurality of valves each include a load sense port having an integrated check valve that includes a metering orifice.

The invention relates to a movable base for transporting equipment by land, in particular aeronautical equipment. The movable base comprises a frame including two side arms designed to move parallel to one another and means for rolling on the ground, which are connected to the frame. Each side arm comprises lifting means designed to move the equipment vertically and to tilt same between the side arms.

A movable platform storage device for off-floor storage including a substantially vertical support member (column) anchored to a concrete floor that defines the deployment axis. The movable platform is connected to the vertical support member (column) and can be raised or lowered to one of any plurality of positions oriented generally transversely to the deployment axis by means of an electric servo-motor power unit and wire cable lifting system. The column is available in different lengths to accommodate ceiling height limitations and desired raised platform heights. The platform storage device can be used as a single stand-alone unit or multiple storage units can be combined in a configuration that creates a unique electric/mechanical powered elevated mezzanine system with increase elevated storage area. The servo motor electric/mechanical wireless power system on each of the combined storage lifts can be programmed identically so that all platforms will raise and lower simultaneously. The strength of the unique angled column design and wrap around moveable carriage equipped with a back-brace system (that may be modified) allows the invention to support and lift a variety of adjustable platform configurations that may be needed for various storage applications. Most customers will want to install the storage lift column as close to a wall as possible to maximize the garage floor storage space under the raised platform. The standard adjustable platform is either a square or rectangular configuration. This platform configuration would not allow the column to be placed tightly into a corner and valuable under platform garage floor storage area would be lost. The issue is resolved with a “corner” designed platform that allows the column to be installed very close to the interior corner of the garage. This uniquely designed platform can be manufactured in various sizes. Alternative adjustable platform configurations can also be used. These various platform configurations can be installed on the invention because of the unique wrap around carriage's ability to support alternative back brace systems and under platform support systems to which various platform sizes and configurations may be attached. These (almost infinite) adjustable platform configurations allow the column to be installed and operated so that a minimum amount of available garage floor storage space is compromised.

A vehicle lift includes a mechanical lift including a platform and at least one extension being movable relative to the platform. Systems, devices and methods are disclosed.

The hoist comprises a base, first and second lower arms, first and second upper arms, and one or more blocking members. The first and second lower arms are pivotally coupled to the base. The first lower arm is pivotally coupled to the first upper arm. The second lower arm is pivotally coupled to the second upper arm. The lower arms and upper arms are adapted to move between an unraised condition to a raised condition. Each of the blocking members is adapted to move between a supporting position and a non-supporting position. Each blocking member, when in the supporting position, prevents the lower arms and upper arms from moving from the raised condition to the unraised condition.

In the context of service and maintenance of heavy road vehicles, apparatus is provided that is configured to engage and support a rack and manoeuvre it into position relative to the vehicle to facilitate removal and installation of the wheels. The rack has a frame with a base and a pair of arms, each arm being pivotally attached to opposite sides of the base to pivot between an open configuration and a folded configuration. The apparatus may be expanded and contracted between an expanded configuration, where the rack engagement assembly is configured to engage the rack in the open configuration, and a contracted configuration where the rack engagement assembly is configured to engage the rack in the folded configuration.
