Alkmar2 meter 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: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
Alkmar.Stop the suspension cage.
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.
.When the wall bracket adopts non matching standard products, design calculations should be carried out.
Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Construction electric elevators outside the lightning protection range
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: A limit switch should be set at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers), so that the suspension cage can stop
Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, 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.
Before operating the construction electric elevator and safety considerations should be taken into account in stage design. According to relevant national regulations 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.
Every theater is a public place with a large number of people,AlkmarZoomlion Electric Elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements,AlkmarWalking electric elevator, and record the inspection results.
quality.The verticality of the guide rail frame should meet the requirements of the specifications.
When using lifting equipment, the workbench should be kept in a horizontal state.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
Alkmar.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Monthly maintenance and inspection of hydraulic lifting platform rollers, intermediate shafts and bearings, oil cylinder pin shafts and bearings, boom hinge shafts and bearings for wear. Add some oil to each part to extend the service life of the lifting platform bearings. The quality and level of hydraulic oil. The lifting platform should be raised throughout the entire process, and at this position, the hydraulic ground should be 40-50 millimeters higher than the bottom of the box. If the hydraulic oil becomes dark,AlkmarSmall electric mobile elevator, sticky, or has foreign objects such as gravel, it should be replaced in a timely manner (32 # hydraulic oil). Annual maintenance and inspection of all hydraulic pipelines and joints of the lifting platform. The pipeline must not be damaged, and the joints must not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform, blow out the plunger with compressed air, tighten the joint, remove the oil filter, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
