The invention provides a knuckle boom loader having a knuckle boom, an operator seat, and a hydraulic system. The hydraulic system comprises a hydraulic fluid reservoir, a hydraulic pump, and hydraulic fluid lines. The knuckle boom loader further comprises an operator elevator having an elevator platform. The operator elevator has both a lowered position and a raised position. The elevator platform is closer to the operator seat when the operator elevator is in the raised position than when the operator elevator is in the lowered position. Also provided are methods for operating such a loader.

A barrier system for platform lifts to prevent access to an opening once the platform lift is lower than the floor. The system includes a platform lift configured to move in a housing. At least one upright member is receivable in the housing, and is moveable in an up and down direction. A lever is disposed in the housing in a manner in which it will engage with the platform lift as it moves into the housing. The movement of the lever because of this engagement moves the upright member out of the housing to create a barrier.

A configurable service lift for servicing a utility vehicle in a cantilevered elevated condition. A carriage is carried on a vertical mast for travel between its lower and upper ends. The carriage independently supports the inboard and the outboard ends of the utility vehicle using at least one inboard platform and at least one outboard attachment carried on a boom. The inboard platform attached to the carriage and supports the inboard end of the utility vehicle. The boom extends longitudinally rearwardly to a distal lifting end upon with the outboard attachment is secured. The distal lifting end is moveable relative to the carriage in three directionsvertically, longitudinally and laterally. Retractable outrigger legs can be added for stability. The service lift can be a stationary fixture or configured with a towing package for mobile use. Optional tool holding accessories and an integrated waste oil receptacle are possible.

A tower for a material handler includes a housing surrounding an interior space. The tower has an interior mounting system including a base plate through which a plurality of interior mount openings pass. The interior mount openings are located at positions of the base plate that are interior of the housing. In some embodiments, the tower is part of a material handler that also includes two stabilizers located on opposite sides of the tower, a platform located above the tower, and a boom projecting away from the platform.

A fork-arm lift tractor includes a vehicle body, a supporting plate disposed above the vehicle body, a lifting device for driving the supporting plate to be lifted, a front and rear fork-arm assemblies, a front and rear fork-arm drive assemblies. The front fork-arm assembly includes two front fork-arms rotatably disposed at the supporting plate. The rear fork-arm assembly includes two rear fork-arms rotatably disposed at the supporting plate, and the front and rear fork-arms may be deployed or retracted from both sides of the supporting plate. The front fork-arm driving assembly includes a front transmission part, and a front power device disposed at the supporting plate and may drive the front transmission part to move horizontally linearly so as to rotate the two front fork-arms. The rear fork-arm driving assembly has almost the same structure of the front fork-arm driving assembly and is used to rotate the two rear fork-arms.

A jack for lifting a small wheeled utility vehicle such as a lawn mower. The jack includes spaced bars having a lever actuated jacking mechanism therebetween. A base cross bar is carried by the jacking mechanism up and down the same and has spaced cradles for receiving the wheels of the utility vehicle therein. The spacings between the cradles and within the cradles are adjustable for adapting to the wheels of the vehicle. The jack also includes a base bar extending away from the bars for stabilizing the same and movable to a stored position.
