Abstract: The disclosed subject matter is directed to a hydraulic steering shear-fork aerial work platform that comprises a running chassis and a lifting device. The running chassis includes a chassis body and a running device that comprises a left wheel carrier, a right wheel carrier, a linkage frame, and a steering oil cylinder. The left wheel carrier and the right wheel carrier are rotatably installed on the chassis body through wheel carrier shafts. The two ends of the linkage frame are respectively hinged to the left wheel carrier and the right wheel carrier. One end of the steering oil cylinder is installed at one end of the linkage frame, and the other end of the steering oil cylinder is fixedly connected with the wheel carrier shaft through an installing plate.

Abstract: An aerial work platform with protection device of electronic sensing type includes: a vehicle, a telescopic transmission component pivotably installed on the vehicle and an operation platform connected to a distal end of the telescopic transmission component. The operation platform comprises a bottom plate, a circular fence disposed on a perimeter of the bottom plate and a control panel installed on the circular fence; the control panel has a barrier formed on its perimeter, the barrier comprises two side bars located at two lateral sides of the control panel, a protection device of electronic sensing type electrically connected with the control panel is disposed on the barrier, and the protection device of electronic sensing type comprises an optical transmitter and an optical receiver which cooperate with each other and are faced towards each other.

Abstract: The present invention relates to field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a telescopic connection component and aerial work platform. A telescopic connection component for telescopically connecting a telescopic transmission component and an operation platform of an aerial work platform together includes: an outer arm, an inner arm slidably disposed inside the outer arm and capable of being moved out from one end of the outer arm, and a forearm telescopic cylinder disposed between the outer arm and inner arm. The telescopic connection component has longer horizontal reach so that the operation platform is capable of moving to a further region in a horizontal direction, thus increasing working range of the aerial work platform. In addition, the telescopic connection component has higher structural strength and stability and accordingly, it also improves safety of the aerial work platform.

Abstract: The present invention relates to the field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a vehicle with a low gravity center and aerial work platform. The vehicle includes a vehicle frame, a power system, a fuel tank, and a hydraulic tank all of which are mounted at a side of the frame. Correspondingly, the embodiment of the invention also provides an aerial work platform which provides better off-road performance and grade-ability, can work in complicated environment, and owns a longer horizontal reach and larger working range. Moreover, maintenance and repair cost is decreased, lifetime is extended, integrity is higher and appearance looks better.

Abstract: The present invention relates to the field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a vehicle with a rotary control box and aerial working platform. The vehicle with a rotary control box includes: a vehicle frame, a driving system disposed on the vehicle frame, and a control box; the control box is disposed at a lateral side of the vehicle frame in a rotary manner; and the control box is electrically connected with the driving system. embodiments of current invention makes it possible to manipulate with ease the aerial work platform to perform corresponding motions by an operator standing on the ground and, this kind of manipulation is quick and accurate. In addition, more convenience and human-friendliness is brought. At the same time, life time of relevant components of the aerial work platform is extended, and maintenance and repair cost is further reduced.
