Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.The undercut length of the weld mm should not exceed % of the weld seam, and the depth should not exceed .mm.Wafangdian,WafangdianMobile hydraulic lifting platform,The hydraulic pump also has an impact on the flow rate of hydraulic oil. If the hydraulic pump is used for a long time, it is also prone to problems. When the speed of the hydraulic lifting table slows down, it is necessary to check whether the oil supply of the hydraulic pump is firm and firm.Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.Namanyers, Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of meters, if possible, please use safety protection measuresThe optional configurations of a fixed lifting platform include manual hydraulic power,WafangdianScissor fork hydraulic lifting table, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking

For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.The hydraulic elevator has no counterweight device, which improves the utilization rate of the well surface.Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.original,Lines of various safety equipmentOil leakage from the oil cylinder: If it is a problem with the sealing ring, it is recommended to replace it with a new one.The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.

A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism hydraulic mechanism, electric mechanism,WafangdianFixed hydraulic lifting platform, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.Discount,The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.Each box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.Wafangdian,Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.The development of elevators is at its peak, as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.
