The pulley shall meet the following requirements: the rope groove shall be curved， and the groove bottom radius R shall meet: r≤ R≤ r， where t is the radius of wire rope; The depth shall not be less than times the diameter of wire rope; The pulley guiding the wire rope upward shall prevent foreign matters from entering; Effective measures shall be taken to prevent wire rope from falling out of groove; The included angle between the wire rope and the plane normal of the pulley shaft (wire rope deflection angle) shall not exceed °.
6The jacketed lifting platform is composed of platform， telescopic oil cylinder， single or double ladder anti-rotation mechanism， chassis oil tank，Electric elevator price manufacturer outrigger，Solingen1 ton electric elevatorMatters to prevent damage walking wheel， etc. The platform is jacked directly by the telescopic oil cylinder. When the motor is started， the motor drives the gear pump to supply oil. The oil is fed into the oil cylinder through the one-way valve and the electromagnetic channel. The telescopic oil cylinder rises section by section. When the platform rises to a large height， the oil overflow valve unloads， and the oil pressure is kept at a constant working pressure. After the stop， the one-way valve maintains pressure， and the platform stops at a large working position， The platform can stay at a large height at a higher working height. The equipment is suitable for large exhibition centers and tall halls， with an operating height of more than mm. When the oil tank is dumped，Electric elevator price manufacturer it can enter and exit the gate， and is convenient for placement and maintenance. The electric elevator can be equipped with imported wireless operation lifting platform with a large height of up to meters. As a multifunctional and multipurpose lifting and unloading mechanical equipment， the lifting platform has been widely used and applied in many industries and fields， such as factories warehouses， workshops， floors， airports， wharves， decoration， electricity，Electric elevator price manufacturer and so on. The lifting platform has also become an indispensable loading and unloading equipment in the production and life of the whole society.
uUlmWorking at heights is also very common now， and electric elevators are also very popular in the market. Many high-rise transportation works are completed by electric elevators，Solingen1 ton electric elevatorMatters to prevent damage which are efficient and safe. However， attention should also be paid to the installation of electric elevators， otherwise there will be problems. Nobody wants to see this happen. What are the installation precautions for electric elevators?
Principle of rotary valve of electric elevator: when the electric elevator rises， it is necessary to turn the handle to turn the plug to degrees until it is closed， and then turn the drive handwheel to make the plug fall to seal.
AKong BochaVertical lead screw electric lifting mechanism: adopt lead screw transmission mode， which can realize the lifting of double-deck table. Multiple lifting platforms can be formed as required， and different steps can be formed within the range of travel to meet the needs of meetings and performances; Pavilion， platform，Electric elevator, electric elevator, electric lifting platform, electric hydraulic lifting platform - price manufacturer of electric elevator building， pavilion” Ideal props.
XkThe lifting platform shall be maintained monthly to check whether the roller， intermediate shaft and bearing cylinder pin shaft and bearing， boom hinge shaft and bearing of the hydraulic lifting platform are worn. Each part is filled with some lubricating oil to extend the service life of the lifting platform bearing. The quality and level of hydraulic oil. The lifting platform is raised throughout the whole process. At this position， the hydraulic ground should be ~ mm higher than the bottom of the box. If the hydraulic oil becomes dark， sticky or has foreign matters such as sand， it should be replaced in time ( # hydraulic oil). Year-end maintenance and inspection of all hydraulic pipes and joints of the lifting platform. The pipes shall not be damaged， and the joints shall not be loose. All joints must be tightened. Remove and disassemble the lowering valve of the lifting platform， blow the plunger clean with compressed air， and then install it again. Drain and discard the hydraulic oil， tighten the connector and take out the oil filter. After cleaning， clean it with compressed air， and then put it back into the oil tank and connect the pipeline.
Meet the needs of stage process layout with“ Product” In the stage of the song and dance theater arranged in a zigzag pattern， auxiliary lifting platforms are usually arranged in the front， rear， left and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side car platform and the rear car turntable. The front auxiliary lifting platform is used to place the rear car turntable close to the platform entrance. The leveling lifting platform under the side car platform and the rear car turntable can level the table after the side car platform or the rear car turntable is driven out， so that there is no height difference in the whole table， so as to ensure the safety of the performers.
The erection of the parking platform of the construction electric elevator shall comply with the specification requirements.
bSafety rules for multi-pillar aluminum alloy lifting platform Even if you are familiar with other types of aerial work platforms， please read the following items in order to work safely and effectively: personnel without basic operation training are not allowed to use this machine. If it fails to meet the specified conditions of use， it is not allowed to forcibly work the lifting process and lifting status. Mast and platform are not allowed to collide with any obstacle or moving object The ground personnel shall not operate the lower device platform for lifting without the instruction of the high-altitude operator. After lifting， it is forbidden to stand or stack articles under the multi-pillar aluminum alloy lifting platform. It is forbidden to change， modify and discard the safety device.
ZIn order to access from the ground protective fence door during maintenance， the fence door should be able to open from the inside.
QmiddlemanSetting requirements: the landing door shall be installed at the entrance of each landing station. The landing door shall cover the opening with its full width， and the landing door shall not open towards the lifting passage.
wSHigh lifting height side type oil cylinder， stable operation， noiseless， convenient maintenance and long service life.
Here is a brief introduction to some problems that need to be paid attention to when using hydraulic electric elevators. This kind of machinery and equipment provides great convenience for industrial consumption and daily operation， and regularly make records of the repair and maintenance of machinery and equipment， and regularly stop the repair and maintenance of equipment， otherwise it may be caused by temporary neglect.
Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove the rubber or sponge at the contact between the buffer and the car to increase its impact energy; Slipping of rope groove and other causes sudden fall of lift car accident safety tongs. In order to prevent the wire rope from breaking due to lifting. The safety tongs that can cut off the power supply and stop the car from falling should be removed from the car. The car without safety tongs shall not be taken or carried. If it is a simple electric elevator， there should be a safety device (safety stop pin， etc.) to prevent the car from suddenly falling when people load and unload goods in the car; All electric elevators with passengers or passengers on more than three floors (including three floors).
Executive standardjThe counterweight guide rail shall meet the specification requirements.
GThe machine room can be set within the radius of meters of the shaft， with an area of only - square meters.
The connection mode and angle between the wall-attached frame and the building structure shall meet the requirements of the user manual.
qUlmSetting requirements: drainage measures shall be set for the foundation of construction electric elevator to ensure smooth drainage.
zHCivil engineering advantages The pit depth of the guideway lifting platform is generally about -mm， and the top layer is not affected. It can be customized according to the site and environment.
When the horizontal distance between the cage edge and the landing edge or between the cage and the landing door is greater than mm and there is no effective protection of other structures， the landing entrance side protection device shall be equipped.
