When the hydraulic electric elevator is used， it must be stopped by special personnel for operation and maintenance， and the plan for agricultural and sideline products should be established， and the maintenance and inspection of products should be stopped regularly， so as to ensure the safety of each use. There is a lifting channel on the top of it when it is used carefully. It must be firmly stopped and fixed before the relevant operators can stand up， once the electrical system is changed， it is likely to cause serious accidents in the application process. When the operator stops working on the electric elevator，Electro-hydraulic lifting platform he/she must be equipped with a safety belt and wear a safety helmet to do the work. Otherwise， the operator must be prevented from participating in the work site. All operators who operate this kind of equipment must receive special training， and must be qualified and hold the work certificate.

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).

uThe middle rotating shaft of the support rod of the hydraulic lifting platform is inconsistent， which causes the lifting platform to be unable to work normally， the platform has been seriously damaged， and the table has tilted. Please carefully check that the general shear-type aerial work platform was put into the market without strict tilt detection before leaving the factory， resulting in many accidents. For tilt detection， the majority of small enterprises do not pay much attention to the detection of this link，Electro-hydraulic lifting platform This is why there are so many lifting equipment with this problem. The problems of oil cylinder and power unit system are often the problems of insufficient power and unqualified oil cylinder quality， which are also very important for the enterprise itself.

HSetting requirements: drainage measures shall be set for the foundation of construction electric elevator to ensure smooth drainage.

OHow many?The jacketed lifting platform is composed of platform，AlexandriaDingli Electric ElevatorWhat are the key reasons for harming applications telescopic oil cylinder， single or double ladder anti-rotation mechanism， chassis oil tank outrigger， 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 system pressure also reaches the rated working pressure. At this time， the oil overflow valve unloads，Electric elevator, electric elevator, electric lifting platform, electric hydraulic lifting platform - price manufacturer of electric elevator 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， 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， buildings， decoration， and so on. The lifting platform has also become an indispensable loading and unloading equipment in the production and life of the whole society.

cDOperation cost advantage Low failure rate: due to the use of advanced hydraulic system and good methods， the operation failure rate can be reduced to low.

When a N normal force is applied to any position on either side of the door with a rigid mm square or circular flat surface at the locked position of the landing door， the door shall be: -- able to bear without deformation; -- The deformation is not more than mm; -- It works normally after the test.

It is especially suitable for steel structure plants and can be installed indoors and outdoors.

technical servicezThe horizontal distance between the edge of the cage door and the edge of the landing platform shall be no more than mm.

IWhat are the installation precautions for electric elevators? The folding fence and hanging cage of the electric elevator should clean the foundation surface and install the anchor bolts. If the installed construction electric elevator is installed on the basement floor， a pad iron must be used under the screw to increase the bearing surface between the screw and the floor to reduce the friction of the nut on the floor; Insert steel plate shims of different thickness between the chassis and the foundation stone at the anchor bolt to adjust the perpendicularity of the guide rail frame; Install three standard sections， measure the perpendicularity of the guide rail frame with a theodolite， ensure the perpendicularity of each main pipe of the guide rail frame in two directions， and press the four anchor bolts after the guide rail frame is adjusted to be vertical; Adjust the perpendicularity of the fence door frame as above， and press the rest of the anchor bolts; Install the buffer spring; Connect the fence of the other half with the front half with bolts; As above， adjust the verticality and press the anchor bolt， and release the brake on the motor in the cage. (For SC/ type， first install the cage and then install the drive plate).
