A support assembly including a coupler, a first arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end, and a second arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end. The support assembly is movable between a disengaged position and an engaged position. When moving from the disengaged position to the engaged position, the distal end of the first arm and the distal end of the second arm move toward each other.

A grapple for formwork panels includes a scissor arm assembly extending along a longitudinal axis and including at least a proximate pair of arms and a distal pair of arms. The scissor arm assembly is movable between an open position, wherein the distal ends of the distal pair of arms are distanced, and a closed position, wherein the distal ends of the distal pair of arms are in proximity. The grapple further includes a mounting bracket pivotably receiving the proximate pair of arms at the proximate end thereof and a pair of jaw members, each secured to a respective one of the distal pair of arms at the distal ends thereof. Each jaw member has a contact portion, with teeth extending from the contact portion, and having a tip slanted towards the proximate pair of arms, and a deflector guide extending from the contact portion both longitudinally in a direction away from the proximate pair of arms and laterally away from the other jaw member.

Equipment for self-positioning handling of aluminum profiles for rail vehicle, including a handling and lifting mechanism, a steel beam fixed on and being driven to lift by the mechanism, 2-DOF spatial mechanisms fixed on the steel beam and mechanical clamping jaws fixed on a clamping jaw connecting seat; the 2-DOF spatial mechanisms includes a cylinder supporting seat, four connecting members on an outer ring of the cylinder supporting seat hinged respectively to four first connecting rods; wherein, two of the first rods are hinged to first ends of two ball joint connecting rods of which second ends are hinged to the clamping jaw connecting seat; the other two first rods are hinged to first ends of two second connecting rods of which second ends are hinged to the clamping jaw connecting seat; a piston rod of a cylinder center of the cylinder supporting seat driving the clamping jaw connecting seat.

Video sharing is an important part of information exchanging between people in business and in daily personal life. Video sharing between two or more user devices through a server on the Internet usually will consume tremendous network bandwidth. With the supporting of posting and un-posting operations and the dynamic workspace technology introduced in this invention, a server here can centrally coordinate the dynamic secure video sharing between two or more devices while avoiding itself being a bottleneck for the video sharing.

An overhead transport vehicle includes a conveyor to travel along a track, a holder to hold an object to be conveyed, and a lifting driver to lift and lower the holder. The holder includes a base, a holder including a body and a pair of grippers connected to the body in an openable/closable manner, the holder being attached to the base so as to be movable along an opening/closing direction of the pair of grippers, and a first elastic member to restrict, between the base and the body, movement of the holder along the opening/closing direction.

The tool is provided for removing a monument headstone adhered to the base and lifting the headstone. The tool includes a clamp to grip the headstone and a lever arm extending from the clamp to exert a tilting force on the headstone so as to break the adhesion between the headstone and the base. Then, a lifting assembly can be attached to the clamp to raise the headstone.

A system (1) for handling semi-finished metal products (5) including a gripper (3) suitable to grasp at least one semi-finished product (5) laid on a surface (40), a conveyor configured to lift the gripping means (3) from a low position towards a high position, and a tilter (2) configured to rotate the gripper (3) in their high position around a rotation axis (X-X′).

To allow a worker to visually recognize information for assisting transportation of a transport object and the transport object at the same time. A guidance system includes a guidance device and a controller. The guidance device has a display portion. The controller stores information of a target position of a transport object. The controller calculates a detected position which is a current position of the transport object based on a detection result of a detection portion, and further calculates a position deviation which is a deviation of the detected position from a target position. The display portion displays information of the position deviation.

The present invention relates generally to a claw device for installing, removing, and repairing a manhole assembly. Claw device may include a base assembly and two or more arm assemblies. The arm assemblies may be configured to pivot in response to movement of a slide along an axis of a shaft extending upwardly from base assembly. In particular, when a lifting force is applied to the slide, one or more grip pads of arm assemblies may be configured to move inwardly toward the shaft and frictionally grip a surface of the manhole assembly. In one aspect, at least one arm assembly includes an extending member having a plurality of positions for adjusting the length of at least one arm assembly. Advantageously, claw device may be adjusted to accommodate for manhole assemblies of different diameters or other objects having various shapes and sizes.

A closed strap collar for securing cargo by friction, a device for lifting cargo and a lifting method, the collar being formed by a strap and a tensioner which, by tightening the strap around an element, allows cargo to be secured to the element being held or the held element to be raised by pulling the strap collar.
