A lift device includes a base, a boom coupled to the base, and an actuator assembly having (i) a first end coupled to the base and (ii) an opposing second end coupled the boom. The actuator assembly includes a first actuator, a second actuator, and a coupler coupling the first actuator and the second actuator together at or proximate one of the first end or the opposing second end of the actuator assembly. The coupler is pivotally coupled to a pivot point of one of the boom or the base. The coupler pivots with the first actuator and the second actuator about the pivot point.

Gripping equipment for lifting apparatuses of the type comprising: a rigid support framework which is adapted to be fixed/attached to the lifting apparatus; and one or more manually controlled gripping members that are firmly fixed to said rigid support framework, and are adapted to grasp and hold a specific object to be moved; said rigid support framework comprising at least one rectilinear tubular element with polygonal cross-section, which is made of metal and has a sectional modular structure.

A crawler type crane having a base carrier unit having a control unit associated therewith and an upper portion assembly having a boom portion coupled at end to the base carrier unit and to a jib portion at an opposed end. The boom portion includes one or more selected boom sections that are articulatable relative to each other. The crane also includes a multi-function attachment unit that is coupled to the jib portion and has a grappling unit for grasping a work piece and a saw attachment unit for cutting the workpiece. The crane can also include a first fluid regulating device coupled to the jib portion for regulating a fluid to the jib portion and to the multi-function attachment unit and a second fluid regulating device coupled to the boom portion for regulating a fluid to the winch element and to the multi-function attachment unit.

The invention relates to an apparatus for compensating diagonal pull in cranes having at least one boom, having a boom drive for adjusting an angle and/or a length of the boom and/or for traveling a trolley, and having a control/regulation apparatus for controlling/regulating the boom drive. The invention is further directed to a crane having a corresponding apparatus.

A lattice structure is mounted on a work machine, and is detachably coupled to a counterpart lattice structure adjacent to the lattice structure. The lattice structure includes a connector to which an end portion of any main pipe among a plurality of main pipes is connected and to which an end portion of at least one inclined pipe among a plurality of inclined pipes is connected, the connector being detachably coupled to a counterpart connector included in a counterpart lattice structure.

A telescopic jib bracing unit for a mobile crane includes a holding frame which is embodied for fastening to the telescopic jib of the mobile crane and exhibits an open cross-section, the cross-sectional opening of which enables the jib to be retracted into the holding frame, and two bracing supports which are connected by the holding frame to form a structural unit. Two frame parts which form the open cross-section of the holding frame are coupled to each other via a coupling point such that they can be moved with respect to each other. A bracing unit transport system, a mobile crane and a fitting method are also provided.

An additive manufacturing system includes a base having a substantially planar surface, a plurality of support legs to support the hose management system on a ground surface such that the base is substantially parallel to the ground surface, a tower, a pivot connection point disposed on the base, the pivot connection point configured to pivotably attach to a proximal end of the tower, a winch attached to the base, and a winch cable configured to be attached between the winch and the tower. Activation of the winch applies a tension to the winch cable to cause the tower to pivot from a prone position to an upright position.

Components and systems for a flexible tensioning member for construction equipment. A tensioning member is comprised of a fiber having a specific tensile strength greater than 1,000 kilonewton meters per kilogram. The tensioning member connects two components and has an attachment allowing the tensioning member to flex relative to a component. The attachment may provide a system for connecting multiple tensioning members.

A bracket support system to connect a hoist to a connector rod and at least one hoist connector of a tractor, the bracket support system including an upper mask bracket removably disposed on a mounting mask to connect to the connector rod, at least one lower bracket removably disposed on a rear of the hoist, a stiffener bracket disposed on at least a portion of the hoist to prevent damage to the mounting mask in response to lifting at least one object on the hoist, and a support shaft disposed within at least a portion of the rear of the hoist.

A telescopic side arm for a refuse vehicle has an inner and outer boom. A mounting assembly secures the outer boom with a refuse vehicle. A plurality of bearing pads is positioned between the inner and outer booms to provide smooth movement between the inner and outer booms. A plurality of shims is associated with the bearing pads to assure a tight fit between the inner and outer booms.
