A hydraulic forklift is a machine that manually pulls the car body to carry goods and relies on hydraulic cylinders to lift the goods to the required height for stacking. This machine is generally used in warehouses, workshops and other places that require logistics handling, which can relieve workers labor intensity, and improve the efficiency of storage work, but the current hydraulic forklift generally does not have a warning device in the working process, so when the hydraulic forklift is lifting the goods, due to the complex environment in the warehouse, the noise is loud, and the light is dark, it is sometimes in the warehouse. Other workers in the warehouse do not notice that the hydraulic forklift is lifting the goods, and sometimes they accidentally fall back into the working area of the hydraulic forklift or the goods on the hydraulic forklift fall, which may easily injure the staff; The lights are generally hung on the upper part of the roof, which will darken the light between the lower goods. Therefore, when the operator needs to insert the fork of the hydraulic forklift into the gap between the goods, it is difficult for the operator to insert the fork smoothly due to the dark light. It is inserted into the gap between the goods, so it may hurt the goods and cause losses to the enterprise; and the current hydraulic forklifts generally use foot brakes. When the hydraulic forklift is in a static state, it is more convenient to use the foot brake, but when the hydraulic When the forklift is in the moving state, it is difficult for the operator to step on the brake pedal while walking. Therefore, it is necessary to design a brake that is also convenient during the moving process of the fork, and can improve the insertion accuracy of the fork. Mobile hydraulic distribution vehicle with warning function.
