strength testing report.
Spiral electric lifting mechanism: With all the functions of a regular lifting platform
Acceptance: Concrete strength grade C30, the main feature is that the equipment occupies a small foundation pit and has a large stroke. The equipment has a height of only 200-500mm and a travel distance of up to 14m. It is particularly suitable for buildings with stages built on two or more floors due to space constraints.
San Severo .The shutdown device (emergency stop switch) should be non automatic reset type.
Setting requirements: Drainage measures should be set up for the foundation of construction electric elevators to ensure smooth drainage.
.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.
Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
The landing door should meet the requirements of the specifications and achieve standardization.
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.
Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So, how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the bearing capacity of its supporting structure should be checked.
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method,San Severo Electric hydraulic elevator, 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, Tower, Pavilion; Ideal props.
During normal operation,San Severo Electric hydraulic folding elevator, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise,San Severo Small mobile electric elevator, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
Horizontal lead screw mechanical electricity
Service first.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
Setting requirements: The up travel (limit) switch should be able to automatically stop the cage running at the rated speed before reaching the upper limit switch, but should not trigger the up travel (limit) switch as high
Every theater is a public place with a large number of people, 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.
San Severo .The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Setting requirements: The installation and dismantling workers, electricians, and other operators of construction electric elevators should have special construction operations.
