ironLarge electric elevatorAnalysis of the cause of abnormal noise

The advantages and disadvantages of several commonly used electric lifting mechanisms are as follows: hydraulic electric lifting mechanisms: using hydraulic technology, smooth lifting and low noise.

Setting requirements: The wall bracket should use the manufacturer's matching standard products.

iron.Normal operation starts. Click on this free download of construction technical information. Safety limit devices should be installed on electric elevators for construction, with upper and lower limit switches that are sensitive and reliable.

Secondly, for the replacement of hydraulic oil on the lifting platform, it is recommended to replace it every three months. If the frequency of use is not high,ironElectric fork lift table, it can be replaced once a year. The hydraulic oil must be clean, and after changing the hydraulic oil, it must be automatically lifted and lowered 2 to 3 times to ensure that the air in the oil cylinder is completely discharged, maintain sufficient space, and ensure that the lifting platform can be lifted to the rated lifting height.

.The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform, side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.

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, 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, the protective measures taken should comply with the specification requirements.

The pump body adopts an integrated pump station, all equipped with imported high-quality pump stations, which can also be selected according to customer requirements to meet customer ideal requirements.

Word of mouth recommendation.Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc. and the production should meet the design requirements.

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

Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.

Safety performance: Electric elevators not only have the safety device of traditional traction elevators, but also have an overflow valve to prevent excessive system pressure during upward movement

how much.A complete lifting platform accessory can be selected and customized according to different places, venues, meet various different needs demonstrate multifunctional, and win market demand. In modern industrial transportation processes, lifting platforms have begun to play an increasingly important role, whether in airports,ironThree phase electric elevator, docks, warehouses, floors, workshops and other places that require rapid loading and unloading of goods, they have played a very practical value, It has also brought great contributions to the entire industry and even the entire economic development. However, long-term operation and use of these devices inevitably lead to wear and consumption, and regular maintenance and upkeep are essential. Otherwise, both work efficiency and utilization rate will decrease, and at that time, the gains and losses will outweigh the losses.

Installation position of upper limit switch: Under normal working conditions, the distance between the upper limit switch and the upper limit switch is 0.15m for SC type construction electric elevators, and 0.15m for SS type construction electric elevators (person)

Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods,ironElectric elevator cargo elevator, the operating failure rate can be reduced to a low level.

iron.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.

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.

Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications record the inspection results, and report any problems found to the user unit.
