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.

A bollard setting and installation system for efficiently installing a bollard wall without any restrictions relating to proximity to water or flood plains. The bollard setting and installation system generally includes a setting frame which is positioned on a ground surface. A plurality of bollards is positioned on the setting frame in a desired spacing and orientation to form a bollard wall. A vehicle having a vehicle arm connected to a lifting frame is positioned such that the bollards are secured to the lifting frame by clamps in the desired spacing and orientation. The vehicle may then move the lifting frame to position the lower ends of the bollards in an opening in the ground surface. Concrete may be poured to encapsulate the lower ends of the bollards. The lifting frame may then be removed, with the bollard wall being free-standing in the ground surface.

Provided are a manned pole-climbing work platform and a pole-gripping mechanism thereof. The pole-gripping mechanism includes an arm and a distal pole-gripping mechanical hand. The distal pole-gripping mechanical hand includes a front jaw, a rear jaw, a forward-threaded rod, a reverse-threaded rod and a preloader. The front jaw and the rear jaw are articulated with the arm through pivots. The preloader is configured to drive the forward-threaded rod and the reverse-threaded rod to rotate synchronously. The forward-threaded rod and the front jaw are articulated with each other through a front thrust-nut composite pivot. The reverse-threaded rod and the rear jaw are articulated with each other through a rear thrust-nut composite pivot. The front jaw and the rear jaw are openable or closeable relative to each other.

The present disclosure refers to a mobile telescopic hydraulic crane, which may include at least one service opening in a terminal portion of a telescopic section adjacent to at least one hydraulic connector, wherein said at least one service opening is configured to allow access for a hand tool from the outside of the telescopic section to establish or disassemble a hydraulically sealed connection between a flexible hydraulic pipe and associated hydraulic connector within said telescopic arm. The at least one service opening allows for a quick and simple replacement of each hydraulic pipe within the telescopic secondary arm without significantly reducing the carrying capacity and reach of the crane.

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.

A boom clamp attachment has a gib frame, a boom quick-connect, a shaft arm axle, a shaft arm torque assembly, and at least one gib clamp assembly. The gib clamp assembly has a clamp support member having a first gib clamp at a first end and second gib clamp at a second end. The gib clamp has a fixed finger and a moveable finger, the moveable finger controlled via hydraulics. The boom clamp may hoist, tilt, and position an assembled section of panels.

A system for transporting a carrying plate may include a lifting assembly comprising a carriage, and a carrying assembly. The lifting assembly may include a carriage having one or more lifting arms configured to lift the carrying assembly at least in part by one or more carrying arms of the carrying assembly. A carrying assembly may include a perimeter frame surrounding a perimeter of a carrying plate, one or more carrying arms attached to the perimeter frame, and one or more indexing pins extending or extensible inwardly from the perimeter frame. The one or more indexing pins may detachably secure the carrying plate to the perimeter frame. A method of transporting a carrying plate may include detachably securing a carrying plate to a perimeter frame of a carrying assembly and transporting the carrying assembly with a lifting assembly.

A device for lifting a steel reinforcement mat includes a grid of parallel rods in a first direction and, placed thereon and fastened permanently, parallel rods in a second direction, each according to a predetermined mesh width. The device has a hoisting frame suitable for being secured to a hoist. The hoisting frame has supporting elements on opposite sides positioned in such a way that when the hoisting frame rests on an uppermost steel reinforcement mat of a stack thereof, each supporting element is located in a respective mesh. The supporting elements are configured to slide in the first direction in such a way that during lifting, the supporting elements each support with a respective supporting surface exclusively rods in the second direction of exclusively the uppermost steel reinforcement mat. The supporting elements on the opposite sides slide away in the opposite direction to each other.
