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: What's the difference between a horizontal jack and a vertical jack?: Horizontal jack is used as a rigid top lift working device, lifting heavy light small lifting equipment in the small tour through the bracket at the top. It is a kind of widely used in heavy vehicles or mobile devices supporting equipment weight, adjust the equipment level of an important hydraulic components, it is mainly used for industrial, transportation and other departments as vehicle repair and other lifting and supporting work.

Q: Lifting equipment, chain hoist need maintenance?: Monthly maintenance limit switch inspection and maintenance, please push the limit switch on the axle by hand, check whether the movement is flexible, if not flexible, please push the shaft with butter lubrication. Check whether the screws of the main parts are firm or not

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: What are the heavy lifting units commonly used in hoisting operations?: Clasp for rope buckle (also known as resurrection, Jack rope, wire rope and rope buckle), or the connection between rope buckle and component rings. It is a wide range of connections used in lifting operations. The clamping ring is composed of two parts: a bent ring and a pin, wherein the clamping ring is divided into two kinds of straight and U-shaped shapes according to the form of the bending ring; the connecting form of the pin and the bent ring is divided into a bolt type and a draw pin type clamping ring and a semi-automatic clamping ring.The snap ring must be forged; shall not exceed the prescribed load when in use; pumping pin clasp is often used for column hoisting, it can be fixed in place on the post, can be on the ground in advance in pin tail rope, pull the pin, unsling, avoid the pick button of high-altitude operations, reduce the safety factor, improve the lifting efficiency. But in order to improve the safety, the bolt type clasp is used when the weight of the column is big.

Q: Working principle of mechanical screw jack: Screw jack, also known as mechanical jack, is driven by the screw through the screw, screw or nut sleeve as a lifting device. Ordinary screw jack by thread self-locking function support heavy, simple structure, but the transmission efficiency is low, return slow. The self - lowering screw jack has no self-locking function and is equipped with a brake. When the brake is relaxed, the weight can fall rapidly and shorten the return time, but the jack structure is complicated.

Q: Rack type lifting machine, rack press, rack lifting machine: Rack type lifting machine is mainly used for railway track laying and maintenance. The utility model is widely used for lifting and supporting the installation of various heavy objects and equipment in industrial and mining enterprises, as well as bridge erection.

Q: Do you know the manufacturer of small lifting equipment?: Lifting equipment company operating mainly include: imports of high-end hand chain hoist, hoist, electric hoist, pneumatic hoist, permanent magnetic chuck, electronic hanging, lifting shackle, hardware tools, steel plate lifting clamp, sling, take-up binder, lifting sling, lifting tool and riot lifting chain etc..

Q: The permanent magnet (permanent magnet sucker) the principle of who knows?: The permanent magnetic chuck, also known as a permanent disk, is a magnetic chuck because it is known for its long or permanent magnetism. According to its use, application range can be classified, because of its convenient operation, energy saving and environmental protection, is widely used in the machinery manufacturing industry.

Q: What is the working principle of a screw jack? What's the difference between an ordinary hydraulic jack and an ordinary hydraulic jack?: The screw jack is a pure machine, and the two jacks are fundamentally different in principle. Open the relief valve. Press the small piston constantly, and the big piston can shrink back under the action of gravity
