Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a hydraulic one-way valve, also known as a hydraulic lock,KiswaldaMovable hydraulic lifting platform, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.Kiswalda,In case of strong wind of level or above, rainstorm,Kiswalda10 meter hydraulic lifting platform, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.Hajduboszormeny,Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal,KiswaldaManufacturer of scissor lift, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking operations above meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.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.Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.Personnel engaged in high-altitude operations must be healthy, and those who suffer from mental illness, or have been identified by a doctor as having hypertension, heart disease, or other diseases that are not suitable for high-altitude operations are not allowed to participate in high-altitude operations. When it is found that staff members are drinking alcohol or feeling low spirits, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment leveling, and alignment points, and confirm that the foundation meets the requirements before construction.Work courses,Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.Solution: Check if the performance of the legs is good, even if the butter is polished to increase its properties.
After hours of elevator operation, perform minor repairs to the mechanical and electrical systems.Quality assurance,This paper briefly introduces some matters needing attention in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic system of elevators and hydraulic elevators and other hydraulic machinery are oil storage, heat dissipation, separation of air contained in oil and elimination of foam.The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.Kiswalda,When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level , please stop using it; When the lifting height exceeds meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platformEmergency descent device: When a power driven chain elevator loses power there should be a device to make the workbench emergency descend.Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
