Hel BrownSuppl
Hel BrownManufThe product has a sturdy structure, a large load-bearing capacity, smooth lifting, simple and convenient installation and maintenance, making it an ideal and economical cargo conveying equipment for replacing elevators between low floors. The editor will share with you some common knowledge about daily maintenance of outdoor elevators: When personnel enter the interior of the lifting platform for maintenance, they must hang the elevator to prevent sudden lowering of the platform and causing casualties.
The current fixed hydraulic elevators are mainly enclosed or meshed lifting channels surrounded by buildings and light steel structures, and use hydraulic cylinders to lift the platform. Its main components are as follows: the lifting passage part: a closed or mesh frame surrounded by buildings or light steel structures, a fixed hydraulic lifting platform with steel guide rails installed on both sides of the internal driving part: it is equipped with hydraulic driving motors, oil pumps, safety valves fixed hydraulic lifting platform speed control valves The small oil tank cylinder part of hydraulic components such as directional valves: composed of one or more cylinders of a lifting cylinder, or a lifting shear fork frame a straight top platform, forming a door system. The closed or mesh platform door or door system consists of a steel structure, with manual and automatic doors. Generally, open platforms do not have doors. The electrical part is composed of power, signal, safety, lighting, with guide rollers or guide shoes on both sides. The platform bottom can be connected to the lifting cylinder or lifting scissor type steel frame auxiliary parts There are enclosed (i.e. cabin type) or open types, which are composed of hydraulic pipe fittings, pipelines, pressure gauges, and steel structure bases; Safety devices: safety valves, limit limits, door electromechanical interlocking, rupture valves, emergency switches, and electrical short circuit protection.
Hel Brown.It can be seen that the hydraulic lifting platform needs to carefully inspect the hydraulic and electrical systems before use so as to facilitate its use.
Troubleshooting: When the elevator power light is turned on, the motor rotates press the up button, but the lifting platform does not rise. This may be due to the reversal of the motor after the three-phase power supply is connected, just change the two phase wires of the heavy machine.

If there are problems inside the elevator and electrical professionals are present, any components of the hydraulic system should be disassembled and repaired in a completely depressurized condition.
The above detailed introduction, I believe everyone has a certain understanding of elevator selection, so that they can have a clear goal when choosing, and then choose the elevator that is suitable for customers.
Special manufacturing processes. Everyone knows that fixed loading and unloading platforms can have a good market performance, which is closely related to the advanced manufacturing technology of manufacturers. In fact, there are still many advanced processes that can be used nowadays. If used appropriately in daily production and manufacturing processes, manufacturers use many special manufacturing processes during production, which makes it highly stable in application.
To understand the operation of the mechanism, the main focus is on whether it is normal and whether there is noise during use. When faults are found, timely troubleshooting is necessary to ensure the normal operation and use of the machine. During installation, it is necessary to disassemble or adjust the rotating mechanism. In this case, it is necessary to ensure that the rotating mechanism can be parallel to the centerline of the reducer and the centerline of the gear, and of course, the meshing clearance should also be appropriate. If this is not appropriate, then the machinery cannot operate normally.
If hydraulic elevators are used on campus, especially after school every day, there are a large number of parents and there are also safety hazards such as people and cars. Maintaining order in such situations is a good idea.

After 5000 hours of operation of the elevator, repair the mechanical and electrical systems.
Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.
Secondly, the maintenance of the guide rail type hydraulic lifting platform is also very simple, using oil cylinders and chain transmission, so the maintenance workload is not very high. Moreover, this type of lifting cargo elevator has a very compact structure and uses fewer bearings, resulting in a longer service life.

The characteristics of hydraulic lifting platforms are obvious, such as their relatively light overall weight and good maneuverability, allowing even a single person to operate, making them relatively suitable. The mast columns of its system are equipped with guide wheels, so its lifting and lowering are relatively stable during use. Of course, attention should also be paid to the structure of the hydraulic lifting platform to ensure its compact structure, so as to ensure its size during transportation. Only in this way can you enter the car of a general elevator, and then you can smoothly open the door. Of course, some small and narrow channels are also possible, so we need to pay attention to this point.
Firstly, an obvious advantage is its high safety performance. The guide rail hydraulic lifting platform adopts heavy-duty chain transmission, hydraulic explosion-proof oil pipes, safety devices to prevent overloading, multiple limit switch protection, door and power outage protection, leakage protection, and multi-layer building interaction. Therefore, the safety factor of the guide rail hydraulic lifting platform is still very high, much higher than that of ordinary platforms.
