Belo HorizonteHydraulic 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, 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.
The hydraulic lifting platform often checks the connection status of each part and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
Belo Horizonte.The hydraulic system of the fixed lifting platform of the hydraulic cargo elevator is equipped with anti fall and overload safety protection devices, and operation buttons can be set on each floor and the lifting platform workbench to achieve multi-point operation.
Lines of various safety equipment
.Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.
Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit,Belo Horizonte10 meter lifting hydraulic platform, the oil is supplied by the pressure limiting variable pump and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
Hydraulic elevators and load-bearing oil cylinders can directly act on the foundation pit, requiring low shaft strength, and brick or brick concrete structure shafts.
For hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
Mobile is a type of cargo heavy machinery equipment with good adjustment reliability and wide application fields, suitable for automated production lines
Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.
system.Set up warning lights around the guide rail type hydraulic cargo elevator equipment, each working period is divided into three different stages: starting, constant speed lifting, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
Belo Horizonte.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.
Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
There are many reasons for unstable workbench descent, such as overload, unstable support, severe eccentric load, etc. In response to the above reasons,Belo Horizonte8-meter hydraulic lifting platform,Belo HorizonteElectric lifting platform Hydraulic lifting platform, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.
