This equipment is made up of sliding worktable, scissor hydraulic lifting device, manual control box and rolling ball table, etc. Among them, the sliding worktable can move horizontally in two directions through bearing combination in the course of application. Besides, it can also rotate in certain angle by this structure. The lifting fixture is the main device to finish the action of lifting and lowering. It is composed of hydraulic driving system, scissor fork, centralized lubrication system and hydraulic grease cylinder, etc. This hydraulic driving system adopts imported pumping station and the grease tray is installed under the whole device in order to keep AGV running path clean, make its performance reliable and its driving stable. The rolling table is of one board structure. The universal rolling ball is installed on the table so that it is convenient for the rear axle pallet to move in all directions on the table. Guiding fixture is installed around the table to avoid pallet slide off the table or overturn.

AGV lifting equipment can be operated manually to ascend and descend. Operator can run it through manual operation box or footswitch at the two sides of the lifting equipment. After AGV enters into assembly path and track the body, operator opens the lock equipment of slide flat and uses lifting manual control box to operate lifting equipment. After assembly, press the completion button, the lifting equipment will automatically return to its initial position. Then operator locks the slide flat. Each lifting equipment is installed with a coder, which can make feedback on the lifting position. Lifting height, including altitude to be lifted and maximum height can also be set
through software.

The height from the plane of the lifter table to the ground is a very important
dimension, which directly decides if AGV system can meet the requirements of field application. All basic specifications of the two kinds of lifter introduced above are set for initial parameter dimension. They can be amended or adjusted according to customers specific dimensions so that field application requirements can be achieved finally.

Based on the specific characteristics of car assembly, SIASUN develops AGV standard products for car engine front & rear suspension final assembly. This type of AGV can realize the car assembly with distance of 2450mm-2850mm between the center point of engine and rear axle. The solution is to design the rear axle lifting framework to be able to move forward and backward along the guided rail as shown in the picture, so that the distance between AGV front and back lifting axle can be adjusted to adapt to different wheelbases for various types of vehicles. According to different wheelbases of vehicle type, marks are made in proper positions so that operator can adjust the wheelbase rapidly and accurately. The rear axle lifting fixture can lock in any position. The operation is easy and saves labor.
