A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far The hydraulic oil tank has more heat dissipation effect.
The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, folding arm lifting platforms,Page numberCan hydraulic pressure automatically lift and lower, and sleeve type lifting platforms according to their different modes of movement.
Page number.Based on experience, new steel wire ropes will not suddenly break when used under normal circumstances, unless incorrect operation or safety protection devices fail, as the load borne by the steel wire may exceed its breaking capacity. The damage to the steel wire rope of the cargo elevator is mainly gradually formed during long-term use. After a certain period of repeated bending and friction, the steel wire on the surface of the steel wire rope will experience bending fatigue and wear, and the steel wire on the surface layer will gradually break. At this point, if it cannot be used again, it should be replaced in a timely manner to ensure the safety of the hydraulic platform.
When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.
.Each box, distribution box, etc. should be kept clean and promptly cleaned of dust on electrical equipment.
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
When using hydraulic elevators, the main causes of noise are mechanical mechanism failures, hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
Low power consumption: Hydraulic elevators are driven by the pressure generated by their own weight, greatly saving energy. Long term improvement of various brand products such as elevator manufacturers, with complete designated products and quality assurance
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,Page numberStraight top hydraulic lifting platform, 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.
query.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
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.
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, 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.
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,Page numberHydraulic lifting platform and hydraulic lifting platform, 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, buildings, airports, sports venues workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising, etc.
Cylinder diameter and hydraulic oil flow rate. The speed of the hydraulic lifting device is inversely proportional to the cross-sectional area of the cylinder rod and directly proportional to the flow rate of hydraulic oil. When the hydraulic elevator runs slowly, 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.
Page number.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, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, stable lifting, and high safety.
