Described is a telehandler (1) comprising an operating arm (10) to which is coupled a winch (2) equipped with a motor-driven drum (21), on which is wound a cable (22) to which is fixed a hook (23), also comprising first means (51) for detecting the quantity of cable (22) unwound.

An aerial device system includes an adjustable railing and a coupler. The adjustable railing is positionable around at least a portion of a base platform and is movable between a stowed position and a deployed position. A height of the adjustable railing in the deployed position is greater than a height of the adjustable railing in the stowed position. The coupler is communicatively coupled to the adjustable railing and is configured to detect a position of a component of an aerial device of the aerial device system and move the adjustable railing based on the detected position of the component of the aerial device. A method of controlling a cab guard safety system for the aerial device includes detecting the position of the component and moving the adjustable railing to a stowed position or a deployed position based on the detected position of the component.

The invention relates to a tread device for walking on a crawler carrier of a work machine having a caterpillar drive, wherein the tread device has a holder that can be installed at the crane, in particular at the crawler carrier, at which at least one tread surface is provided, characterized in that the tread surface lies on the upwardly disposed surface of a crawler chain of the caterpillar drive in the state installed at the work machine and the lower side of the tread surface comprises at least one sliding element to ensure a sliding or rolling relative movement between the crawler chain and the tread surface.

The present invention relates to a telescopic boom having a coupling section at whose lower shell at least one luffing cylinder mount, in particular a bolt mount, is centrally provided for fastening at least one luffing cylinder, wherein at least two closed sheet metal box structures for the load transmission from the luffing cylinder mount into the structure of the telescopic boom are provided at the support metal sheets of the luffing cylinder mount.

A small engine transport device for moving small engines comprises a plurality of adjustable arms sized and configured for receiving a vehicle engine and legs configured to counter-balance the adjustable arms when the adjustable arms are bearing the weight of a vehicle engine. Each adjustable arm may have a hand to bear against a vehicle engine. A hydraulic jack could be used to adjust the vertical position of the adjustable arms when bearing the weight of a vehicle engine. The adjustable arms and/or the legs could be foldable to lower the profile of the small engine transport device for storage.

A vehicle-mounted reel lifting apparatus for rotating the reel to dispense or wind the reelable material. A driven wheel engages the rim of the reel at a plurality of reel lifting arm pivot positions, such as sliding alongside the lifting arm in an axis parallel with the lifting arm. The driven wheel is capable of engaging with the reel at any position of the lifting arm. A linear drive mechanism allows the driven wheel to travel up and down the lifting arm to accommodate various reel sizes. The lifting arm may incorporate an automatic locking slot having a spring-driven locking mechanism. The lifting arms may also be mounted with a mounting bracket having a pattern of slots to enable the lifting arms to be selectively mounted in a narrow configuration or a wide configuration.

An SCR-quipped rough terrain crane in which a urea water tank is laid out at the optimal position is provided. A rough terrain crane is equipped with an exhaust emission control device that is laterally adjacent to a diesel engine. The exhaust emission control device is provided with a urea water tank and is laid out in a rear portion of at a vehicle body. The urea water tank is disposed on a front side of the exhaust emission control device. The urea water tank is disposed in the vicinity of the left side of the diesel engine when viewed from the rear side of the vehicle.

A hydraulically actuated liftable and lowerable hook of a crane has a hydraulic system comprises at least one working machine with a hydraulic motor driving a winch. At least one drive machine comprising a pump is connected directly or indirectly to at least one of the working machines by means of two connections via corresponding working lines, which serve as a feed or return depending on the operating state of the working machine. A lowering brake valve is provided in one working line and is connected to the other working line via a control line such that the lowering brake valve is displaceable against a restoring force by pressure, which prevails in the other working line and is forwarded via the control line, from the blocking position of said valve into a through-flow position for lowering the hook by means of a primary winch.

A tribologically modified polyoxymethylene polymer composition is disclosed. In accordance with the present disclosure, the polyoxymethylene polymer composition contains a tribological modifier, such as polytetrafluoroethylene, in combination with a stabilizer package. The stabilizer package can include a guanamine compound in combination with at least one carboxylic acid salt. The stabilizer package minimizes formaldehyde emission.

A boom system includes a base assembly and a boom assembly. The boom assembly includes a boom including a plurality of boom sections. The plurality of boom sections includes a lower boom section coupled to and extending away from the base assembly and defining a proximal end of the boom and an upper boom section defining a distal end of the boom. The boom assembly further includes an attachment coupler assembly coupled to a boom section other than the upper boom section and configured to receive a first implement. The boom assembly further includes an implement connector positioned at the distal end of the boom, the implement connector configured to receive a second implement.
