main parameters of SC200/200 construction hoist The SC200/200Construction Elevator is an external construction hoist with a three- drive rack-and-pinion mechanism. It has a rated loading capacity of 2 tons and a rated hoisting height of 150 meters. A simple alteration can change it into a single-cage construction elevator with a rated loading capacity of two tons. The SC200/200Construction Elevator is equipped with a state-patented safety device which can brake automatically in case of accidental fall. The driver element on top of the cage is safe and reliable and convenient for maintenance. The elevator with a maximum hoisting height of 300 meters is widely used for construction work such as industrial and civil construction, bridge construction, underground mining, large chimney construction and the shipping industry. It can be used for transporting materials or people vertically, as a permanent or half-permanent lift, or in places like storehouses and tall towers.

Q:Working principle of mechanical screw jack: When the brake is relaxed, the weight can fall rapidly and shorten the return time, but the jack structure is complicated. The screw jack can support heavy load for a long time, the maximum lifting capacity has reached 100 tons, and it is widely used. When the lower part is loaded with a horizontal screw rod, the heavy object can be moved at a small distance.

Q:Lifting equipment, chain hoist need maintenance?: Do not let the crane exposed to outdoor rain, so as not to affect the host for a long time, such as device and outdoor, please use the canvas goods plastic cover and above or prevent the host host hypothesis shed rain, not to seal the way.

Q:What's the difference between a pneumatic balancer and a spring balancer?: Without manpower, the workers' time and energy can be greatly saved. Spring balancer is a mechanical upgrade, the internal wire rope for lifting, can not realize the suspension of heavy load. The lift is also limited in weight, but the price has advantages over the pneumatic balancer. The two are not too comparable.

Q:Please explain how to prevent the safety accidents in the process of tower crane installation and disassembly: The tower crane (also known as the tower) with crane and tower body mutually vertical shape, so it can be installed in the nearby construction engineering and effective working range than other types of cranes. The working height of the tower crane can reach 100 ~ 160m, which is especially suitable for the construction of high-rise and super high-rise buildings. In addition, the operation is convenient and the amplitude is simple, and has been widely applied in the construction. However, due to the uneven assembly and disassembly or other reasons, tower crane safety accidents happen frequently. In view of the serious accidents occurring in the loading and unloading of tower cranes in recent years, this paper discusses the problems concerning installation, demolition, operation, maintenance and safety management of tower cranes.

Q:When should the temporary fixing tool for lifting work be removed?: Phosphating coating to improve the wear resistance and corrosion resistance of steel wire, not easy to wear and corrosion, is to improve the service life of wire rope reasons, smooth steel wire rope is being completely eliminated.

Q:Working principle of mechanical screw jack: Jack by the manpower through the screw drive, screw or nut sleeve as the top lift, jack screw thread self-locking action on the support, to avoid severe vibration should be top jack jack jack users to use process, according to the use of regular inspection and maintenance is made of high quality alloy steel material, more durable than similar products, as a commonly used lifting tool, Baoshan screw jack is a good helper to improve work efficiency. In the use of Jack, if only one, then be sure to select the weight of the center of gravity, and then point to the center of the jack, so as to prevent the lifting process in the tilt, resulting in accidents.

Q:Classification of lifting tools: Lifting tools can be divided into light and small lifting equipment, hoist and overhead monorail system according to different structures.

Q:I want to know what the principle of magnetic suspension is. Why does it make magnetism disappear?! What is the structure like?!: Magnetic crane also known as the permanent magnet by high performance NdFeB permanent magnetic material magnetic system, by turning the handle, change the magnetic system of magnetic workpiece holding and releasing.

Q:What are the characteristics of HHXG type inverted chain chain electric hoist?: Structure of party workers to operate a variety of mechanical lifting tools related products such as: black bear small diamond chain electric hoist, hoist, hydraulic jack, three spring balancer, Longsheng plate clamp, dragon masunaga magnet, horse sand hydraulic jack, straight weight shifting device, permanent magnet lifter, ultra thin hydraulic cylinder, mini chainhoists.

Q:What important attention should be paid to large equipment?: 1, the operation is not allowed to pull the operation power cord.2 work personnel should be familiar with lifting scheme and safety measures.3. Lifting tools and tools should be regularly maintained and tested.4, must by the corresponding qualifications professional card holder carries on.
