An adjustable strut that includes an outer housing configured to receive an extendable member, and an extending mechanism with a gear system configured to convert rotation motion of an input mechanism into linear translation of the extendable member.

A strut may be interposed between a first floor plate and a second floor plate of a multi-story building, wherein the first floor plate is disposed overtop of the second floor plate. The strut includes a first post section and a second post section. The first post section includes a first portion that is coaxial with, annular to and slidably disposed within a second portion of the second post section. A damping actuator is interposed between the first post section and the second post section, and is arranged to dynamically control a position of the first post section in relation to the second post section. The strut also includes an accelerometer. A controller is in communication with the accelerometer and the damping actuator, and controls the damping actuator to control the position of the first post section in relation to the second post section.

A support is provided, comprising a first bar with a first abutment element, a second bar with a second abutment element, and a guiding device by which the first bar is displaceably guided on the second bar. An actuating device which acts on the first bar and which comprises an actuating element is arranged on the second bar. A displacement of the first bar in a first direction of displacement can be initiated by actuation of the actuating element. The first direction of displacement is a direction of increase in distance between the first abutment element and the second abutment element. The actuating device comprises a blocking device which blocks a displacement of the first bar in relation to the second bar in a second direction of displacement, which is opposite the first direction of displacement, at least when no active releasing action occurs at the blocking device.

A mount may include a base having a socket. A leveler may be positioned within the socket and may be configured to be adjustably engaged to one of a plurality of posts of a shelving system. A fastener may secure the leveler to the socket. The leveler may be adjusted to change the height of the post in relation to other of the plurality of posts in the shelving system, and thereby level the shelving system.

A lightweight multifunctional supporting device and a method for calculating a jacking force thereof. The lightweight multifunctional supporting device includes a supporting frame and a jacking device, the jacking device includes a screw rod and a jacking seat, the screw rod (21) is provided vertically and is fixed on the supporting frame, the jacking seat is provided thereon with a vertical threaded hole and is provided with a lateral rotation rod, and the screw rod is in threaded connection with the threaded hole. The method for calculating the jacking force of the supporting device above.

A pass-through head assembly is provided. The pass-through head assembly may include a central shaft, a plurality of support bars, a seat, and a seat support plate. The central shaft may extend between a first end plate and a second end plate. Each end plate may define an aperture that aligns with an interior cavity of the central shaft. The plurality of support bars may extend from the central shaft and the second end plate. The seat and seat support plate may each be circumferentially disposed about the central shaft and define apertures that are sized to allow the seat and the seat support plate to pass over the central shaft and the plurality of support bars. The seat may be configured to support one or more beams. The seat support plate may be disposed between the seat and the second end plate.

The disclosure relates to a telescopic support prop, which has a leg with a lower leg part and an upper leg part. The upper leg part has a plurality of vertically spaced through holes. A locking pin is releasably connected to one of the vertically spaced through holes of the upper leg part. A cap is connected to the locking pin, the cap having a fastening sleeve put over an end of the locking pin, the cap further having a spring for bearing against the exterior of the lower leg part.

A fail-safe release mechanism for use with patient positioning support apparati having a base structure and a patient support structure, to prevent collapse of the patient support structure during disconnection of the patient support structure from the base structure at outboard ends thereof.

A system for laterally supporting a vertical shoring post is provided. The system includes a head and a jaw assembly, the jaw assembly movably mounted to the head, the head configured for selective engagement with a shoring post, and the jaw assembly configured for engagement with a beam that provides lateral support to the shoring post. The head comprises first and second arms that extend in the same general direction and when engaging the shoring post the first and second arms are disposed upon opposite sides of the shoring post. The jaw assembly includes a fixed jaw and a movable jaw, the moving member pivotably connected to the fixed jaw, wherein the fixed jaw and movable jaws are configured to receive an end of the beam therebetween.
