A pipe spreader comprising: a frame, and; a pair of mutually cooperating pipe engagement assemblies, coupled to the frame, for engaging a pipe; each of the pair of mutually cooperating pipe engagement assemblies comprises: at least one spreader assembly, the spreader assembly includes a spreader beam and an end manipulator coupled to the spreader beam, wherein at least a portion of the spreader assembly is arranged to be selectively removable from the pipe engagement assembly.

The present disclosure relates to a gripping device includes a casing and at least two gripping assemblies. Each of the gripping assembly includes a fingertip, a connecting rod assembly and an attaching assembly. A first end of the connecting rod assembly is connected to the fingertip, and a second end of the connecting rod assembly is rotatably connected to the casing. The attaching assembly is disposed on a side of the connecting rod assembly facing the target object to be gripped. The gripping device is configured to be switched between a first gripping mode and a second gripping mode. In the first gripping mode, the gripping device clamps the target object by the fingertips cooperating with each other. In the second gripping mode, the gripping device adheres and/or adsorbs the target object by the attaching assemblies cooperating with each other to implement a gripping operation.

A portable hoist assembly is mounted on a scissor lift. The hoist includes an elongate cable wound on a shaft. The cable has proximate and distal ends. A pulley is mounted on the cable intermediate the proximate and distal ends. In use, the pulley is secured to the ceiling of a building structure.

A multifunctional suspension device for mechanical engineering, relating to mechanical engineering equipment. The multifunctional suspension device includes a supporting base, wherein guide rods are symmetrically arranged on the left and right sides of the upper surface of the supporting base, the ends, away from the supporting base, of the guide rods are fixedly connected with a top plate, a first screw rod is arranged between the guide rods on the left and right sides, the upper and lower ends of the first screw rod are rotatably connected with the top plate and the supporting base, a first driving motor is arranged in the supporting base, second nuts drive arc-shaped clamps on the two sides to move inwards at the same time through push rods and clamping rods to clamp and fix a tubular part.

A Multi-Armed Lifting Accessory is disclosed herein which is compact and transportable in various deployments. The Multi-Armed Lifting Accessory is advantageous and useful as it has hingedly connected loading and support arms attached to a main lifter body. The supporting arms are spring loaded allowing the Multi-Armed Lifting Accessory to stably engage with irregular shaped objects such as barge lid or a skid steer loader and allows for flexible engagement and balanced lifting operations.

A hoist hook includes a main plate, a first slide plate, a second slide plate, a first base, a second base, a pair of hooks, a flywheel, and rack. The first slide plate and the second slide plate are fixed to each other and are configured to be suspended from a radio-controlled unmanned aircraft and to slide vertically relative to the main plate while sandwiching the main plate. The first base and the second base are fixed to each other and are configured to slide vertically relative to the main plate while sandwiching the main plate. The pair of hooks are each rotatably linked to the first base and the second base. The flywheel is rotatably fixed to the main plate. The rack engages with the flywheel and is fixed to the first slide plate.
