The invention relates to a manual displacement mechanism and a device provided therewith. The displacement mechanism includes a displacement frame including a housing, and a wheel that is provided at a first end of the housing. The wheel is moveable relative to the frame between a displacement position where the device can be displaced and a stationary position where the device is in a stationary position. The mechanism also includes a steering handle that is operatively coupled to the wheel with a linkage mechanism that is configured for moving the wheel relative to the frame. The steering handle is connected to the displacement frame at a second end of the housing. The mechanism also includes a connector configured for connecting the manual displacement mechanism with the pallet truck or lifting device. The connector includes a hinge for hingedly connecting to the device and a connector spring element configured for providing a pre-tension on the wheel.

According to some embodiments, a vehicle restoration system comprises a first base unit, a second base unit, a third base unit, and at least a fourth base unit, an adjustment member positioned at each base unit, the adjustment member being configured to support a surface of a vehicle along an upper end of the adjustment member, the jack being configured to selectively change a vertical position of the upper end of the adjustment member, a first side member coupling the first base unit to the second base unit, a second side member coupling the third base unit to the fourth base unit, a first strut coupling the first base unit to the third base unit, and a second strut coupling the second base unit to the fourth base unit.

The present disclosure is a hydraulic jack including a housing that supports a reservoir, a motor, a pump assembly, and a lift assembly. The housing includes a lift portion in which the lift assembly is at least partially supported, and a power supply portion configured to removably receive a power supply. The motor is configured to receive power from the power supply. The pump assembly receives a rotational output from the motor to generate a flow of hydraulic fluid from the reservoir. The lift assembly is extendable between a retracted position and an extended position in response to the flow of hydraulic fluid and is configured as a three-stage lift assembly with a first stage that extendable in a first manner, and second and third stages extendable in a second manner.

An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand pli) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand pli) style bracing with screw jacks and a means of stabilization during substructure raising. The substructure bracing reduces the overall length, reduces the upper and lower box spans, and balances the raising loads, subsequently lowering the transport weight of the side box such that a commercial walking system may be integrated into the side box and remain there during transport while maximizing the operating drill floor height while minimizing the transport height.

A grinding mill for pulverizing material includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish in which the material is disposed, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the grinding mill can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

The present disclosure relates to vehicle traction apparatus and radiation imaging check systems. One illustrative implementation may comprise two parallel tracks, two sets of traction mechanisms and a driving unit, wherein the tracks are disposed on a ground. The two sets of traction mechanisms may be respectively disposed on the two tracks. Further, the driving unit may be adapted for driving the two sets of traction mechanisms to synchronously move along the two tracks. In some embodiments, each of the two sets of traction mechanisms includes a body, a cantilever, a lifting driving mechanism and a wheel supporting assembly, and may include features such as the body being mounted on the track, the cantilever being disposed parallel to a direction of the tracks, and/or both ends of the cantilever being respectively connected with the lifting driving mechanism and the wheel supporting assembly.

A leveling and stabilizing jack includes an intermediate member joining first and second lifting sections. Each lifting section includes a cross beam, a leg, a brace, a foot, a motor and a drive screw. The motor powers the drive screw, which is operably associated with the leg, to cause the leg to extend away from or retract toward the cross beam depending on the motor's direction of rotation. A motor control can control the motor of each of the lifting sections independently in a manner that results in leveling of the jack when deployed.

The present invention relates to a lifting system for lifting a vehicle and method therefor. The lifting system according to the invention includes a frame with a moveable carrier configured for carrying the vehicle, with the carrier including a carrying part and a guiding part; a drive which acts on the carrier and is configured for raising and/or lowering the carrier relative to the frame; a locking system for locking and unlocking the moveable carrier relative to the frame; and a controller configured for controlling the height of the carrier. The locking system includes a lock actuator, a locking rail, a locking drive configured for moving the lock actuator between a locked state and an unlocked state, and a lock and is configured for engaging and/or disengaging the locking rail in response to a movement of the lock actuator.

The present invention is directed to the problem of maneuvering heavy cargo to an ergonomically correct lifting height for countless industries, including for equipment stored on firefighting and rescue vehicles. Mechanical and electrically actuated horizontal drawer slides and extendable arms enable loads to be moved outside of an enclosure or storage structure for easier access.

A lifting device that includes a central portion and first and second laterally extending lifting arms. Each arm extends away from opposite sides of the central portion and includes a lifting cradle disposed on a distal portion of the associated laterally extending lifting arm. Each laterally extending lifting arm and associated lifting cradle is operable to securely engage with a gear leg of a vehicle and lift when an upward force is received by the central portion.
