The manual hydraulic pallet truck is the most commonly used transportation tool for enterprises, but it is less known about the use of the pallet truck and the working principle, and in the subsequent use and maintenance, operating according to its principle can also greatly extend its life; manual hydraulic transportation Vehicle: The principle of hydraulic transmission, using oil as the working medium, transmits movement through the change of the seal volume, and transmits power through the pressure inside the oil. 【Power part】Convert the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. [Executive part] Convert the oil pressure energy input by the hydraulic pump into mechanical energy that drives the working mechanism. For example: hydraulic cylinders, hydraulic motors. 【Control part】Used to control and adjust the pressure, flow and direction of the oil. For example: pressure control valve, flow control valve and directional control valve. [Auxiliary part] Connect the first three parts together to form a system, which plays the role of oil storage, filtration, measurement and sealing. For example: pipelines and joints, fuel tanks, filters, accumulators, seals and control instruments, etc. The pressure applied at any point on a certain volume of liquid can be equally transmitted in all directions. This means that when multiple hydraulic cylinders are used, each hydraulic cylinder will pull or push at its own speed, and these speeds depend on The pressure required to move the load. In the case of the same load capacity range of the hydraulic cylinder, the hydraulic cylinder carrying the smallest load will move first, and the hydraulic cylinder carrying the largest load will move last. In order to make the hydraulic cylinder move synchronously to achieve the load at any point To be lifted at the same speed, control valves or synchronized lifting system components must be used in the system. Precautions for use and safety regulations 1. Wear overalls, safety shoes and gloves when operating the truck. 2. When transporting by truck, the truck should be locked to prevent the truck from moving. 3. When the truck is not in use, pull the brake knob 12 to the braking position to keep the truck in a braking state. 4. When the truck is used on a motor vehicle, it must move slowly to ensure safety. 5. In an emergency, you must immediately pull the brake knob to the braking position, put the truck in a braking state and immediately release the descending knob to place the goods on the ground. 6. The truck cannot be parked on slopes and emergency passages. 7. When transporting goods on a slope, the operator must operate the pallet truck very carefully, and must make the operator operate on the slope. Put to the lowest. 9. Trucks are not allowed to park on the slope. 10. Trucks are not allowed to park in places that obstruct traffic or affect work. 11. Trucks are not allowed to be used in rainy environments. 12. Operators of this truck are not allowed to sit on the truck or stand on the truck to operate the vehicle. 13. Pallet trucks are not allowed to turn on slopes. 14. When stacking goods, the goods should not be too high to prevent the goods from falling or the truck during transportation. There is a danger of overturning. 15. It is forbidden to use this truck to transport people. 16. No other people are allowed around the truck operation area to avoid sudden failure of the truck in motion and possible casualties. 17. Before pushing the truck into the elevator, the operator must ensure that the elevator can bear the total load of the truck and goods, the total weight of the operator and other people on the elevator. When entering the elevator, be sure to let the load enter first, not the operator. When the load or the truck enters or leaves the elevator, other people are not allowed in the elevator 18. The truck should be stored in a dry and ventilated environment. 19 When the weight of the cargo is more than 2500kg, two people are required to operate the truck together to reduce Operating force.
