What are the common faults of hydraulic lifting platforms? The hydraulic lifting platform's oil cylinder is severely damaged, and uneven damage to the inner sealing ring or obstacles inside can easily cause uneven stress, a 20 year old brand with competitive prices and guaranteed quality!
Are there any damages to the wires and cables of the department. We need to quickly bandage and replace the damaged department.
.The seat belt needs to be inspected every six months, with a load of 225 kilograms. The test time is five minutes. After the test, check whether the seat belt is broken or deformed, and keep records of the experiment. Any unqualified seat belts should be immediately stopped from use.
The main structure and purpose of a guide rail elevator: The mechanical part of a guide rail elevator mainly includes three parts: a lifting device, a track device, and a belt changing device. The lifting device is mainly used to suspend the person being lifted which is the core part of the entire mechanism. The track device is mainly used to provide movement trajectory, making operation more smooth. The belt changing device is used to switch tracks when the elevator is about to pass through a door. The internal structure of the lifting device is mainly composed of gear mechanism, bracket, worm gear, guide mechanism, lifting arm, upper and lower shells, etc. The gear mechanism mainly includes large and small gears, winding pulleys, central shafts and safety devices composed of stop buckles and torsion springs.
Elevators are now very popular among people and can easily transport goods to high-rise buildings. Among them, hydraulic elevators are more popular among people, and people can choose the one that suits them according to their actual situation. However, during normal work it is important to pay attention to the lifting speed of hydraulic elevators and avoid making mistakes. So what factors will affect the lifting speed of hydraulic elevators?
In the construction elevator, the switch box also has leakage protection equipment, and its wires and cables have good insulation without leakage. The metal passing through the wires is not rusted, and its damage is close to zero. His steel wire rope should comply with the corresponding configuration requirements, without any issues of strand breakage or shrinkage, and of course, the number of broken wires should not exceed the corresponding standards. His pulley movement is very flexible.
System: Anti type electronic control system, remote control system, PIC system.
The correct construction inspection of the airport is to first inspect the foundation to see if there is any water accumulation and to see if the grounding system meets the requirements. We also need to see how the structural bolts of this frame are tightened, and whether there are any cracks in the welds. We need to set them according to the instructions. In mechanical transmission, there are also many safety equipment for elevators.
Installation materials.Hydraulic oil should be kept clean and replaced every 6 months; When repairing, maintaining and cleaning the elevator, be sure to support the support rod.
The pressure of the lifting platform is very important. When lifting goods, the pressure of the lifting platform will test the weight of the goods. If it is overloaded, the general lifting platform will prompt,Nai meihengManual pressure relief of hydraulic lifting platform, which serves as protection. Therefore, now lifting platforms are equipped with pressure gauges. Hydraulic machinery should remind everyone to pay attention to the following points: the precautions for using small lifting platforms are based on pressure. Their load-bearing capacity is very poor and their size is small. When using the lifting platform, it is necessary to pay attention to its use. If overloaded, it will cause structural damage to the lifting platform. We have mentioned this many times before when using it.
When working in a hot environment, pay attention to heat dissipation.
Each department's electric brush should be kept clean, and the brush pressure should be adjusted to ensure that its area is not less than 50%
Service first.Elevator customers all have overloaded use of elevators. Although elevators have a large overload capacity in design, the hidden dangers brought by such use are very large, which can easily cause damage such as oil cylinder roof fall and elevator bracket deformation. So it should be summarized as follows: Maintenance of elevators must be equipped with full-time elevator operators who have undergone on-the-job training, and illegal operation and use are strictly prohibited.
When the lowering valve is open and the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power,Nai meihengFixed hydraulic elevator, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly.
When conducting high-altitude operations on dangerous edges such as roofs, suspension bridges, slopes, or cliffs, guardrails or safety nets should be installed on the side facing the air, or safety belts or ropes should be used.
Nai meiheng.The second is that the steel will have obvious thermal expansion effect at low temperature. Although this property of steel will be taken into account when designing and manufacturing hydraulic elevators, the environment is different after all. Under low conditions, the steel will have some unstable performance, such as hardness increase, toughness decline, etc. At this time, more attention should be paid to the maintenance of equipment to keep key parts to avoid dry grinding.
The lifting platform has been inspected and debugged before leaving the factory, and all technical indicators meet the design requirements. When in use, only the power supply needs to be connected, and the hydraulic and electrical systems basically do not need to be adjusted.
How to install and use the bearings of the elevator? During the process of using the bearing device of the elevator, we cannot always ensure that the bearing device has the right orientation, which inevitably leads to some devices not being in place or bearing displacement. Once these problems occur in the device, it will cause the clearance between the bearings to become too small, and then make it impossible for the inner and outer rings of the bearings to be in the same rotation center. So it is necessary to use specialized tools when installing bearings, and in the future, it is also necessary to use a testing instrument to test the bearing installation, in order to ensure the success of the bearing installation.
