Belo HorizonteThe landing door should meet the requirements of the specifications and achieve standardization.
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
Belo Horizonte.Fully autonomous lifting is widely used in various high-altitude work fields, such as factory maintenance, airport maintenance, the manual pump can be operated to pump high-pressure oil to raise the car to the nearest floor position
.The wall bracket of the construction electric elevator should be intact and reliably fixed and so on; How to use electric elevators correctly to extend the service life of the equipment and be flexible
Manual pump: When the system malfunctions, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet,Belo HorizonteElectric lifting platform 2 meters, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, and verified by experts.
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, the door should be able to withstand and have no deformation; - Deformation not exceeding 30mm; After the test, it worked normally.
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.
Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.
The magnetic directional valve returns to the fuel tank. To ensure stable landing 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 landing speed does not change due to heavy objects. It is adjusted by the saving valve
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.
equipment maintenance .Drainage measures need to be considered around the foundation. (Drain the accumulated water on the foundation).
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
It is reported that a fixed electric elevator has good lifting stability and can only be used for fixed operations,Belo HorizonteIndoor small electric elevator, making high-altitude operations easier
Quality inspection report.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.
Check the starter potential when the lifting table is not raised or the voltage is too low when the motor load is working. Voltage hydraulic range allowed&
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.
Belo Horizonte.Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented,Belo Horizonte6-12 meter fully automatic elevator, 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.
According to the needs of different performance genres, using a lift can make the theater have various forms such as an end stage using an orchestra pit lift can combine a framed stage with a large lip or even an extended stage. In an experimental theater, an extended stage, an island stage, an intermediate stage, a T-shaped stage, or a hall.
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, Terrace, Tower, Pavilion; Ideal props.
