peasElectric elevator mechanismHow to reduce the severity of the accident

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 safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than 0.75m; If the rated speed is not greater than 0.7m/s, the safety distance can be 0.40m.

peas.When a single steel wire rope is excessively stretched, the Electrical safety device shall stop the operation of the electric lift.

From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.

.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.

The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).

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,peasHand propelled electric elevator,peasElectric mini elevator, and installation

For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all,peasSmall electric winch elevator, especially if any damage or malfunction is detected and corrected or repaired in a timely manner. Careful inspection and maintenance at this time can save costs and avoid larger problems, resulting in costly repairs.

market.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

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.

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.

From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery

market price.Electric elevators used in various places.

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.

Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.

peas.High lifting height, using side mounted oil cylinders, stable operation, noise free easy maintenance, and longer service life.

Setting requirements: For construction electric elevators that operate in multiple shifts the handover system should be implemented, the door may not meet the above requirements
