Li ShiElectric pillar elevatorShape and position size and linearity

When applying a normal force of 300N to any position on either side of the door using a rigid 5000mm2 square or circular flat surface in the locked position of the landing door,Li ShiHand push electric elevator, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.

Construction electric elevators outside the lightning protection range

Li Shi.. The shutdown device (emergency stop switch) should be installed outside the ground protective fence; b) Pulley room (if any. Pulley room refers to a room where only pulleys or speed limiters and electrical equipment are installed; c) hanging cage top, if

Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.

.When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.

Installation verticality deviation guide rail frame erection height, h/mH≤ 7070100150H& gt; 200 verticality deviation/mm≤ (1/100h≤ 70≤ 90≤ 110≤ 130 pairs of steel wire rope construction electric elevators, the verticality deviation of the guide rail frame should not exceed (5/1000) h.

To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot,Li ShiElectric aluminum alloy elevator, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.

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.

Stop the suspension cage.

Acceptance: Concrete strength grade C30, strength testing report.

Manufacturing cost.Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion Terrace, Tower, Pavilion; Ideal props.

Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.

The safety notice board for construction electric elevators should be prominently placed on the hanging cage for the rated load capacity and rated number of passengers of the construction electric elevator. It is strictly prohibited to use construction electric elevators beyond the rated load capacity or rated number of passengers.

When the wall bracket adopts non matching standard products, design calculations should be carried out.

Direct labor.Human improper operation is the main factor causing malfunctions in scissor type electric elevators. When stacking goods, electric elevators should stack the goods neatly, 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, it may cause the electric elevator to lose balance. After the goods are stacked completely, so that they are not afraid of the goods during the lifting process; Careless; Scattered down

The safety overtravel of limit switches and upper limit switches should comply with regulatory requirements.

Secondly, for the replacement of hydraulic oil on the lifting platform, 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.

Li Shi.The scissor type electric elevator is a widely used high-altitude operation special equipment. Its scissor mechanical structure ensures high stability of the lifting platform, wide working platform, and high bearing capacity,Li ShiInstallation of electric elevators for fire protection, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer

Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.

During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.
