A lifter device includes: a pole; a lifting member configured to be guided by the pole; a motor configured to generate power used for ascending and descending of the lifting member; a transmission mechanism configured to transmit the power of the motor to the lifting member; and a preventing member configured to prevent the descending of the lifting member when the power is not transmitted.

An apparatus for aligning tubes of a heat exchanger includes a generally planar body having an insertion end and an actuator end, a first driving member received by the body and extending between the insertion end and the actuator end, the first driving member being movable axially with respect to the body, and a first biasing member operatively connected to the first driving member. The first driving member is actuatable to move the first biasing member between a clearance position in which the first driving member lays generally flat within respect to the body, and an extended position in which the first biasing member extends generally perpendicular from the body.

A support device, preferably for commercial vehicles such as semi-trailers, includes an inner support tube and an outer support tube moveable relative to one another along a longitudinal axis in a retraction and extension direction; a spindle rotated via a gear section and is arranged such that the spindle is stationary relative to the outer support tube; and a spindle nut which is mounted on the spindle, wherein the spindle nut is fixed on a mounting region of the inner support tube, and the mounting region is configured as a support edge facing the longitudinal axis.

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 plié) 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 plié) 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 tire stabilizer includes a partially threaded rod, the rod having a smooth end and a threaded end; a first connector rotatably attached to smooth end of the rod; a second connector threadedly attached to the threaded end of the rod; four first supporting members, each first supporting member including a first end and a second end, the first end of the first supporting member being rotatably attached to the first connector; four second supporting members, each second supporting member including a first end and a second end, the first end of the second supporting member being rotatably attached to the second connector; and two first locking pads, each locking pad being rotatably attached to the second ends of two of the four first supporting members; and two second locking pads, each locking pad being rotatably attached to the second ends of two of the four second supporting member.

An integrated lift and dolly is presented which includes a lift mechanism for elevating a vehicle while simultaneously positioning wheels underneath to enable moving the vehicle as the vehicle's wheels are elevated off the ground. The lift assembly can further elevate the supporting frame to remove weight from the wheels of the lift assembly to allow long term storage without relying on the wheels to support the weight of the vehicle. This integrated lift and dolly lifts and supports the vehicle for storage and also facilitates easier service, inspection and cleaning.

An accessory device for use with an automated guided vehicle (AGV) to assist loading and unloading of components onto the AGV for transport by the AGV. In one example, an electric motor, two lifting devices and an inverted omega-shaped upper platform are used to selectively raise and lower the component. In another example an accessory is positioned on a central portion of the upper platform to engage a pallet to further assist loading, unloading and positioning of the pallet relative to the AGV.

A lifting structure operating precisely and stably at all stages of a lifting and lowering action includes a lifting assembly and a driving assembly. The lifting assembly includes two first links, two second links, and two seats. A first connecting arm of each first link has first and second ends, the first end having a first gear structure. A second connecting arm of each second link has third and fourth ends, a second and complementary gear structure being provided on the third end. The first gear structures are engaged and the second gear structures are engaged. The second end is rotatably connected to the fourth end through one of the two seats. The driving assembly can drive the two seats towards each other to perform lifting or drive them away from each other to perform lowering.

A lifting and support apparatus having a fully lowered position, a fully extended position and many transitional positions. The lifting and support apparatus includes a base portion with a first leg, a second leg, a third leg and a fourth leg hingedly attached thereto and extending therefrom. The apparatus can also include a first lateral support element that the first and second legs are extending toward and hingedly connected to and a second lateral support element that the third and fourth legs are extending toward and hingedly connected to. The apparatus further includes a lift support portion that has a fifth leg, a sixth leg, a seventh leg and an eighth leg hingedly connected thereto and extending therefrom, the fifth and sixth legs extending to and hingedly connected to the first lateral support element and the seventh and eighth legs extending to and hingedly connected to the second lateral support element. In addition, the apparatus has a drive apparatus and threaded shaft for forcing the first lateral support element and the second lateral support element toward and away from each other, which raises and lowers the lift support portion of the lifting apparatus relative to the base portion. A method of raising or supporting an object with a lifting and support apparatus. The method includes placing the lifting and support apparatus in a desired position relative to the object to be raised and supported. The method also includes actuating the lifting and support apparatus to raise the object to a desired height.
