Hong KongPit tWorking at heights is a common practice nowadays, people should also pay attention when using hydraulic lifting platforms, otherwise they can easily malfunction, which may lead to serious consequences. So what are the common faults of hydraulic lifting platforms?
Mobile elevators are generally used in skyscrapers where electric elevators are used, as there is no need to stop midway, so fast elevators are needed. First go to the high-rise sky lobby (high-rise elevator lobby, Skylobby) from the ground,Hong KongSelf propelled electric hydraulic lifting platform, and then transfer to the ordinary elevator to the destination. Some new elevators use elevator pre calling systems, which can pre call designated floors in the lobby. These passenger elevators can be decorated beautifully according to customer needs. Some passenger elevators are also equipped with air conditioning and television, if the high-altitude work platform is overloaded, it may cause damage to the components and cause some mechanical failures.
Regularly check for water accumulation and humidity. It is inevitable for high-altitude work vehicles to drive in rainy and snowy weather, or muddy roads. The bottom and some gaps, as well as the indoor floor, are prone to accumulation of sludge. If the owner does not clean them in a timely manner, this will cause moisture to hide. Therefore,Hong KongPrice of hydraulic lifting platform, the outer edges of the wheel hub, doors, bottom corners of tree trunks, keyholes and wiper brackets, and other areas of activity should be regularly inspected, and the drainage holes of the doors and various parts should be kept unobstructed to ensure that the car seat covers, such as humidity,Hong KongElectric hydraulic lifting platform small, carpets, and floors, prevent rusting of accessories.
.Slow down the smoothness and hydraulic oil of various departments such as the gearbox, gearbox, and external meshing gears according to the requirements in the smoothness table.
When installing disassembling, and adjusting the exhibition organization, attention should be paid to ensuring that the center line of the exhibition organization reducer is parallel to the center line of the gear, and its meshing surface is not less than 70%, and the meshing interval should be appropriate.
The application scenarios of mobile elevators may require several or even dozens of passenger elevators in some office buildings and hospitals. In order to increase the speed, efficiency, and usable area of electric elevators, most high-rise buildings will divide electric elevators into arrays, with each group responsible for a portion of the floors and make different adjustments and scheduling based on the usage mode of different floors at different times.
Now that you understand how to use a hydraulic lift, it provides us with a safe working environment for our operators, and improves the efficiency and quality of the lowering work.
The main categories of aluminum alloy elevators in the Chinese market are based on the structural form of aluminum alloy elevators. Aluminum alloy lifting platforms can be divided into the following types: single column aluminum alloy lifting platforms, which are light and small in equipment, flexible in movement, generally no more than 12 meters in height, and generally have a load capacity of less than 150 kilograms, especially suitable for one person operation.
How to use a hydraulic elevator and whether the emergency stop device is effective is very important during use. If special circumstances arise, the emergency stop can be used. Therefore, before use, it is necessary to carefully check whether all items are normal and ensure the effectiveness of the braking device.
Executive standard.For the introduction of daily maintenance of lifting cargo elevators, the brakes of each organization should usually be inspected and adjusted to ensure sensitivity and reliability. On the surface, there should be no dirt present. If there is any dirt, it must be washed off with gasoline or thinner.
When encountering overheating in the electric motor during daily maintenance of the elevator, it is necessary to quickly park the car, remove obstacles, and then continue running. The motor bearings should be smooth and excellent.

It is necessary to regularly inspect the brake of the guide rail type cargo elevator, and there should be no dirt on the friction surface.
property right.When installing, disassembling, and adjusting the exhibition organization, attention should be paid to ensuring that the center line of the exhibition organization reducer is parallel to the center line of the gear, and its meshing surface is not less than 70%, and the meshing interval should be appropriate.
The main structure and purpose of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. Due to the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is calculated based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the lifting chassis. It is mainly welded from parts such as side plates, and connecting pieces, and all materials are selected. The thickness of the two side plates is selected, and in order to reduce the weight of the bracket, many process holes are designed on the two side plates. Worm gear and worm gear have the advantages of large transmission ratio, compact structure, small impact load, smooth transmission, low noise, and the characteristic of reverse self-locking due to the worm gear and worm mechanism. It can ensure that the transmission mechanism can lock itself when the motor is powered off during patient transportation so a worm gear reducer is selected. The involute worm is used, made of steel, and its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear material is made of polyformaldehyde. Plastic worm gears have the advantages of good processing economy, stable transmission, vibration and noise reduction light weight, wear resistance, and self control, making the design of elevators more humanized.

Hong Kong.What is the new price for fixed elevators?
What types of elevators are there? There are many types of such devices, such as fixed lifting devices and vehicle mounted lifting devices, which can be divided according to the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
Now we have an increasing demand for cargo elevators. Let me introduce the maintenance work of guide rail cargo elevators to you. When we use a guide rail elevator in our daily life, we need to regularly inspect, maintain and maintain it. This not only extends the service life of the guide rail elevator, but also makes it more powerful when working! For example, the transmission part should have sufficient oil, and vulnerable parts must be regularly inspected, or replaced. Mechanical bolts, especially parts that frequently vibrate, such as slewing bearings and lifting arm connecting bolts, should be checked for looseness. If there is looseness, it must be tightened or replaced immediately. Below is an introduction to the 8 steps of maintenance: important maintenance work for guide rail elevators. Regularly check the tire pressure and bearing condition of the guide rail elevators to ensure they are in good condition; Regularly check whether the structure of the bracket and panel is in good condition, and add oil and grease to the bearings and components in a timely manner, once a month; Vulnerable parts must be regularly inspected, repaired, or replaced. Parts that frequently vibrate, such as bolts and slewing bearings, should be checked for looseness. If there is looseness, it must be tightened or replaced immediately.
