The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent 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 descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.Low level doors should be equipped with interlocking devices that can verify their closed and locked positions. The action of this interlocking device should be at the entrance of the cage. Simple use should not interfere with the operation of the interlocking device. The attached wall bracket should use matching standard products. When the wall bracket cannot meet the requirements of the construction site, it should be designed separately. The design of the wall bracket should meet the requirements of component stiffness, strength, stability, etc. and the production should meet the design requirements.Gu Ye,When a suspension cage with a rated load capacity acts on the buffer at a speed greater than the rated speed of .m/s,Gu YeElectric mobile elevator, the average deceleration of the suspension cage should not exceed g, and the time when the peak deceleration exceeds g should not exceedInstallation verticality deviation guide rail frame erection height, the verticality deviation of the guide rail frame should not exceed (/) h.Sialkote,Double layer steel mesh: The diameter of the steel bars is mm, with a spacing of mm.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.
Remind customers that there are still many areas to pay attention to when maintaining and maintaining the lifting platform. We also hope that customers and friends can pay more attention when using it to ensure the safety of personnel and property, regularly maintain and extend its service life, and create greater benefits for the enterprise. What is the matching degree of electric elevators? Everyone has always been confused. In short, the matching degree of electric elevators is how the height of the electric elevator can be combined with the operating height. Electric elevators are not used frequently,Gu Ye2 ton electric elevator, so we must make it clear based on the actual operating height and actual load capacity when using electric elevators. If the frequency is too high, We suggest considering purchasing a guide rail electric elevator or a scissor fork electric elevator. The scissor fork electric elevator can achieve a maximum load capacity of tons, we recommend using a guide rail electric elevator. This type of electric elevator is not easy to malfunction under high-frequency operation, By solving the load capacity and frequency of use, the matching problem of electric elevators is effectively solved. Concept of electric elevator rotary valve: The electric elevator rotary valve is a type of valve that quickly opens and closes, and the rotary valve can reduce oil pipeline channels and optimize line settings.The upward movement of the hydraulic cylinder involves lifting heavy objects, and the return oil from the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve. The additional pressure relief valve is used for adjustment, and the pressure gauge reads the value when observing the pressure gaugeWhen the landing door is closed the full width of the lifting passage opening should be covered.original,Secondly, the lifting platform is driven by electrical energy and lifted by the hydraulic system. During operation, it is necessary to avoid irregular operations. To ensure the normal and orderly operation of the lifting platform and achieve the ideal unloading level, timely inspection of various functions is essential.The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than m. In special circumstances, 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 m. (Article of GB-)When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
Setting requirements: The quality of the standard section should meet the requirements of the product manual. Before installing the construction electric elevator, all components should be inspected, and standard sections and other components with severe wear and deformation should be replaced.details,The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.Mobile electric elevators are divided into: four wheel mobile lifting platform, two wheel traction lifting platform, car modified lifting platform, manual lifting platform, manual lifting platform, and AC/DC dual purpose lifting platformDuring normal operation, the horizontal distance between the closed cage door and the closed landing door should not exceed mm. Otherwise, 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 mm.Gu Ye,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/T; Maintenance, wear, deformation, and corrosion of steel wire ropesDrivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.The safety distance between the outer edge of the upper part of the landing door and the moving parts of the electric elevator during normal operation should not be less than .m; If the rated speed is not greater than .m/s, the safety distance can be .m.
