A gantry system has at least one crane assembly, at least one support post, and at least one hoist. The crane assembly has a stationary base, a rotating base, and a crane arm. The rotating base is attached to both the stationary base and the crane arm in such a ways as to allow the rotating base and the crane arm to rotate while the stationary base remains stationary. The crane arm is supported on its far end by a support post. The crane assembly is configured such that the support post rests on an in-place girder. A hoist is attached and can move along the crane arm to position a railway component, such as a replacement girder and/or a precast panel.

Present embodiments relate to an apparatus and method which separates tie plates. More specifically, and without limitation, present embodiments relate to a tie plate separator which can retrieve tie plates from a pile and separates such for placement on a feeder, such as a conveyor for sequential feeding of the tie plates.

A Building Element Lift Enhancer is described. The Building Element Lift Enhancer provides for the movement and precise placement of building elements such as blocks or sheet products by one worker. The Building Element Lift Enhancer senses the force applied by a user to the building element and converts that user applied force to mechanically assisted force from the Building Element Lift Enhancer, allowing the user to precisely move and handle large, heavy or bulky building elements by direct interaction with the building element.

Provided is a construction method for a fully prefabricated multi-story concrete plant, the construction method may achieve full coverage of a hoisting operation of the large beam and column prefabricated components of a floor by employing a single intelligent hoisting robot, an angle change of the track devices, an angle change of a moving device, and a self-lifting device. It is not necessary to arrange a transition track at the turn of the installation route, which saves space and installation cost, and overcomes the disadvantage of high cost caused by the traditional prefabricated construction mode of multi-story concrete plant, which needs to arrange a plurality of large hoisting equipment. It may achieve the mechanization and intelligence of the whole construction process of the fully prefabricated multi-story concrete plant.

A crane including a crane arm with a crane tip and an implement arrangeable on the crane tip. The at least one part of the implement is movable in relation to the crane tip. A crane controller controls the crane arm and the at least one part of the implement. The crane controller can issue control commands by a user for movement of the crane arm and for movement of the at least one part of the implement. With an implement on the crane tip, when predetermined control commands are issued by a user for movement of the at least one part of the implement arranged on the crane tip, additional control commands for movement of the at least one crane arm can be given off by the crane controller to at least partially compensate for the movement of the at least one part of the implement.

A vehicle system includes a chassis, a prime mover, a body assembly, a boom assembly, an electrical accessory equipment system, and an electric power take-off system. The chassis supports a plurality of wheels. The prime mover is configured to provide energy to drive at least one of the plurality of wheels. The body assembly is supported by the chassis. The boom assembly is coupled to the body assembly and includes a hydraulic actuator. The electrical accessory equipment system is coupled to the body assembly. The electrical accessory equipment system includes one or more batteries, and an electric power take-off system electrically coupled to the electrical accessory equipment system. The electric power take-off system is configured to power the hydraulic actuator using electrical energy from the one or more batteries.
