It is usually composed of a metal frame and wheels, and its carrying capacity is generally between 1-5 tons. The method of car positioning can vary according to the specific production scenario and needs. The following are several common car positioning methods: Manual positioning: The operator uses a forklift or handling equipment to move the car to the specified position, and then uses a fixing tool such as a block or chain to fix the car in the specified position. This method requires a lot of manpower and time, and the accuracy is also low. Mechanical positioning: Use a mechanical device to move the car to the specified position, such as using an electric push rod, pneumatic cylinder and other devices. This method can improve positioning accuracy and efficiency, but requires maintenance and maintenance of the mechanical device. Laser positioning: Use equipment such as a laser rangefinder and a reflector to determine the exact position of the car by measuring the distance between the car and the reflector. This method has high accuracy and speed, but requires high equipment and operating costs.
