and safety considerations should be taken into account in stage design. According to relevant national regulations, in order to prevent accidents caused by the crushing of electric elevators or improper control by drivers. Electric elevators should be equipped with the following necessary safety devices to ensure that the car of the electric elevator stops rising or falling in a timely manner.
Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
Antwerp.Alarm devices can be divided into fixed and mobile platforms, rail type and scissor type (curved arm type) to distinguish between overload or equipment malfunction. Fixed types include: scissor lift cargo elevator, chain electric elevator, and installation
Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly,AntwerpElectric elevator small,Antwerp200 kg electric elevator,AntwerpElectric cargo elevator, which is better than stacking them in the center of the cargo stacking area of the cargo elevator to avoid imbalance between the two ends of the stacking area. Eventually, during the operation of the electric elevator, ropes should be used to lock the goods, so that they are not afraid of the goods during the lifting process; Careless; Scattered down
.The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.
Remind customers that there are still many areas to pay attention to when maintaining and maintaining the lifting platform. We also hope that customers and friends can pay more attention when using it to ensure the safety of personnel and property, regularly maintain and extend its service life, and create greater benefits for the enterprise. What is the matching degree of electric elevators? Everyone has always been confused. In short the matching degree of electric elevators is how the height of the electric elevator can be combined with the operating height. Electric elevators are not used frequently, so we must make it clear based on the actual operating height and actual load capacity when using electric elevators. If the frequency is too high, which effectively solves the problem of load capacity. If the frequency of use is too high and the height is relatively high, we recommend using a guide rail electric elevator. This type of electric elevator is not easy to malfunction under high-frequency operation, By solving the load capacity and frequency of use, the matching problem of electric elevators is effectively solved. Concept of electric elevator rotary valve: The electric elevator rotary valve is a type of valve that quickly opens and closes, and the rotary valve can reduce oil pipeline channels and optimize line settings.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.
The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
Lowering platform, vehicle mounted lifting platform, self-propelled lifting platform, diesel engine curved arm self-propelled lifting platform, folding arm lifting platform, cylinder sleeve lifting platform, aluminum alloy lifting platform, and special
Protective measures should comply with regulatory requirements.
Welcome to inquire.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.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Direct labor.The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
The device should be used within the valid calibration period and operate effectively and reliably. The anti fall safety device should have a valid inspection certificate (or inspection report), and the validity period should not exceed 1 year. Anti fall safety devices have been manufactured for five years
Implementing multiple shifts of homework should fill in and submit records according to regulations.
Antwerp.The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Steel wire ropes, pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, wear, deformation, and corrosion of steel wire ropes
Principle of electric elevator rotary valve: When the electric elevator rises, the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a 90 degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.
