The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.Arxan,When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.Introduction to the unloading lifting platform: The unloading lifting platform is a specialized auxiliary equipment used in conjunction with forklifts for cargo loading and unloading. With it, forklifts can directly drive from the ground into the interior of car compartments for batch loading and unloading operations. The warehouse unloading platform products use manual hydraulic power and do not require power supply. Only one person needs to operate to achieve safe and fast loading and unloading of goods. It can reduce a lot of labor, speed up the flow of materials, and obtain greater economic benefits.Denver,The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn,ArxanHydraulic lifting platform for loading, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn, it should be replaced.The lifting platform is a multifunctional heavy loading and unloading mechanical equipment,ArxanMovable hydraulic lifting platform, which can be divided into fixed and mobile guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.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.

After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.Due to the formation of a flow closed-loop, the oil in the cylinder moves down the throttle valve under pressure, which will cause the temperature of the hydraulic system to rise. Not to mention anything else,ArxanScissor fork hydraulic lifting table, just an intelligent alarm is enough to demonstrate the true value of hydraulic elevators.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.Promise and keep promise,Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, organ type safety protective covers, 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.The lifting platform is placed on a horizontal support surface, also known as hydraulic powered elevators.total cost which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure each load-bearing component must not have deformation or cracks.

The elevator itself has a simple structure and is easy to maintain,Remove the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap first remove the soil around the tank cap, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.When working on the dam crest, steep slopes, roofs, cliffs, towers, suspension bridges, and other dangerous edges, safety nets or protective railings should be installed on the side facing the air. Otherwise, workers must use safety belts. Ice, snow, gravel, and soil on the steep slopes of steep cliffs boarding bridges, or sidewalks must be regularly cleaned, and a -meter high railing must be installed on the outer side. Install an centimeter high side board or soil ridge on the inner side of the railing to prevent falling objects from injuring people.Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.Arxan,Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.
