Reasons why the loading ramp won't rise: Today, loading ramps, trucks, and lifts are commonly used for cargo handling. Because a loading ramp is a mechanical device that assists vehicles in quickly unloading goods, it comes in both mobile and fixed styles and can meet the operational requirements of many mobile scenarios, bringing great convenience. Since loading ramps are mechanical equipment, malfunctions are inevitable during operation. Below, we analyze a common phenomenon with loading ramps—the inability to rise.
Loading dock Reasons for not rising
Nowadays, loading docks, trucks, and lifts are commonly used for cargo handling. Due to Loading dock It is a mechanical device that assists vehicles in quickly unloading cargo. It comes in both mobile and fixed styles, meeting the operational requirements of many mobile situations and bringing great convenience. Because loading docks are mechanical equipment, malfunctions are inevitable during operation. Below, we will analyze a common phenomenon of loading docks—the inability to lift.
1. The viscosity of the selected hydraulic oil directly affects the rising speed. Hydraulic oil is a chemical product and may have adverse effects on health. Direct contact with skin and eyes may cause significant harm. When using hydraulic oil, use 46# hydraulic oil in summer and 32# hydraulic oil in winter, and replace it twice a year. When replacing hydraulic oil, the hydraulic oil should be collected in a container, and appropriate anti-leakage and oil absorption measures should be taken.
2. The oil pipe in the hydraulic system may be leaking. Check the oil pipe and replace it. The hydraulic oil pipe is an important component of the hydraulic lift platform and is an important channel for transmitting pressure.
3. When the pressure of the overflow valve is low, readjust the overflow valve. Under 100% rated load, adjust the oil level to too low, use the oil pump to suck the hydraulic oil to fill it, filter the blockage, clean the filter oil suction section leakage, check the oil suction pipe and joints, and tighten the joints.
4. When the lowering valve is open and the lowering button is released, check whether the lowering valve is energized using a voltmeter. If there is no power, check the circuit and troubleshoot; if there is power, troubleshoot the lowering valve itself. Keep the slide valve of the lowering valve clean and allow for flexible movement.
5 . Loading dock It will not lift when overloaded, mainly because each loading dock has its own rated load. Once overloaded, it will not be able to lift or will not lift. Therefore, a good way is to ensure that the cargo is not overloaded during loading and unloading.
Loading dock Daily maintenance can effectively control friction, reduce wear, lower equipment temperature, prevent parts from rusting, and form a seal. Malfunctions are unavoidable during the use of loading docks. When problems arise, correct solutions should be applied. A simple method is to promptly report the malfunction to the manufacturer, allowing their technicians to perform timely repairs.

Introduction to the civil engineering advantages of rail-guided lifting platforms
Guide rail lifting platform is a kind of non-scissor hydraulic lifting mechanical equipment, used for cargo transmission between floors of two or three-story industrial plants, restaurants, and hotels. It can have a low height of 150-300mm, especially suitable for workplaces where pits cannot be excavated, and does not require upper suspension points. It comes in various forms (single-column, double-column, four-column). The equipment operates smoothly. The guide rails of the guide rail lifting platform are generally made of channel steel, I-beams, and square tubes welded together. It is simple, reliable, and economical for cargo transmission. Hydraulic lifting platforms are multifunctional lifting and handling mechanical equipment with lifting heights ranging from 1m to 30m. They can also be customized according to different user needs.
What is the purpose of a guide rail lift platform?
Rail-guided lifting platforms are widely used and are a popular product on the market due to their various advantages. However, there are many points of knowledge that need to be understood when using them, as many users are not aware of them. Next, let me introduce the uses of rail-guided lifting platforms. Those interested can read on.
How to maintain a guide rail lift platform?
The advantages of rail-type lifting platforms lie in the hydraulic system's anti-falling and overload safety protection devices.
