A pressing device is provided, including: a main body, including a chamber; a pushing assembly, including a retractable mechanism movably inserted within the chamber, a first pushing board connected with the retractable mechanism and a restricting member embedded within the chamber and blocking the retractable mechanism from moving out of the chamber; a hydraulic mechanism, including a tube body which is connected with the main body and communicated with the chamber, a driving rod movably inserted within the tube body and a piston driven by the driving rod, the piston being configured to drive fluid to flow in or out of the chamber. Another pressing device is further provided, differing from the pressing device described above in that: the main body further including a channel, a wall of the chamber including at least one recession which is communicated with the channel.

A telescopic lifting unit with a first segment, a second segment, and a third segment. The first and second segments may be displaced relative to one another, and the second and third segments may be displaced relative to one another. The first and second segments may be moved relative to one another by a motor unit, and the second and third segments may be moved relative to one another by a cable hoist.

A lifting device for lifting shipping containers has an end frame configured to engage with a shipping container. An extension member is rotatably connected to the end frame at a rearward upper pivot point. A support frame is rotatably affixed to the end frame at a rearward lower pivot point. The support frame is further rotatably affixed to the extension member at a forward upper pivot point. Extension of the extension member rotates the support frame with respect to the end plate, causing the support frame to move the end plate upwards, the end plate then lifting the shipping container. A roller wheel is affixed to the support frame and allows the shipping container to be rolled on a surface when multiple devices are used to lift the shipping container off of the surface.

A lifting column includes a first column element and at least one second column element, the at least one second column element being movable relative to the first column element, and at least one damping unit. The damping unit is deformable by a force that acts on an upper side of the lifting column in at least one operating configuration of the lifting column such that the force is at least partly transmitted through the damping unit to a drive of the lifting column.

A jack stand apparatus enables operators to screw adjust a load support column relative to a column support base for fully completing load-bearing distances between loads and opposed support surfacing, and thus improving safety of jack stand applications. The various embodiments of the jack stand apparatus according to the present invention may all be said to comprise a shaft support structure, a shaft construction, a pawl assembly, and a screw mechanism. In the preferred embodiment, the shaft construction is a screw type element and includes external threads. A pawl element is cooperable with the external threads, and the screw shaft construction is telescopically positionable relative to the shaft support structure for engaging an overlying load. The pawl element is engagable with the helical threads for preventing downward movement of the screw shaft construction relative to the shaft support structure for supporting loads thereupon.
