A crane system includes a skid assembly having an operator base and plurality of outrigger assemblies coupled to the operator base that support and lift the base from a first elevation to a second elevation. The crane system also includes a jib crane coupled to the skid assembly. The jib crane includes a pillar assembly coupled to the skid assembly and a boom assembly coupled to the pillar assembly.

A mobile crane supporting device includes a first support segment; a second support segment; and a fixing device having contact portions which are respectively assigned to the first support segment and the second support segment and which can be moved into abutment with each other in order to prevent a travelling movement in any relative position between the first support segment and the second support segment, wherein the second support segment can rotate within and relative to the first support segment about an axis extending in the horizontal direction and transversely with respect to the travelling movement and can thus selectively move the contact portions into abutment with each other or separate them from each other. A mobile crane may include such a supporting device.

A fall protection system includes a base plate defining a first side and a second side defined opposite to the first side. The fall protection system also includes a mast assembly connected to the base plate proximate to the first side of the base plate. The fall protection system further includes a jib inclined with respect to the mast assembly and pivotably connected to the mast assembly. The fall protection system includes a counterweight connectable to the base plate proximate to the second side of the base plate.

Provided is a work vehicle that can be transported by being loaded onto a trailer without having the outriggers removed. The work vehicle (rough terrain crane) is transported by being loaded onto a low bed trailer including a low bed and a high portion (first high bed, second high bed) higher than the low bed in at least one of the front and the rear of the low bed, and includes: outrigger units (front outrigger unit, rear outrigger unit) that are mounted to the front and rear of a vehicle body; and a lift unit that lifts and lowers the outrigger units (front outrigger unit, rear outrigger unit with respect to the vehicle body.

A utility vehicle is configured for use in emergency situations. The utility vehicle includes a base, a set of tracks, and a set of outriggers. The set of tracks is secured to the base configured to move the base through rough terrain. The set of outrigger is configured to be disposed in a stowed configuration and a deployed configuration. The outrigger is disposed above the deck level in the stowed configuration. The outrigger also remains outside the set of tracks in both the stowed configuration and the deployed configuration. The outrigger comprises an upper leg, a lower leg, and an actuator.

A mobile shaft winch includes a carrier vehicle with a vehicle drive, which has an internal combustion engine, a rigid base frame and a rotary platform which is arranged on the base frame via a rotary connection. A drum winch is arranged on the rotary platform with a rope drum which is driven by a winch drive and designed for the winding on and unwinding of a haulage rope. The winch drive includes only an electric motor. A control system is designed for a selective operation of the electric motor on a mains supply system or on an electric generator. The internal combustion engine of the vehicle drive, drives the generator, and the generator and the internal combustion engine are arranged on the carrier vehicle.
