Q:What is tower crane? What are the types and features?
[definitions]Tower crane (tower crane) is called tower crane, also known as tower crane, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
Q:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q:Method for operating tower crane
In the 2.11 operation, when lifting the weight, the weight should be higher than the height of the obstacle, at least 100mm.2.12 when the crane is approaching the track limit, it should slow down and stop in advance.2.13 when lifting heavy objects, not heavy lifting suspension instability, no additional weight in lifting objects, lifting scattered materials or special-shaped components must be used when the wire rope firmly tied to heavy lifting from the ground about 50cm stop, determine the brake materials, lashing and rigging, confirmation before lifting command.2.14 cranes must be adequately illuminated at night.2.15 crane in the stop, rest or midway power failure, the weight should be unloaded, not to weight suspended in the air.2.16 the operating room, no personnel shall enter, prohibited flammable and impede the operation of the items.2.17 is strictly prohibited or promotion personnel riding crane. Landing weight, weight is prohibited to stand.2.18 the boom and lifting pieces of cranes must be in safe distance from overhead transmission lines, and shall comply with the provisions of this schedule 30.1.6.2.19, two cranes in a track or two parallel or vertical orbit on the operation, should maintain the safety of any part of the distance between two machines, the minimum shall not be less than 5m.2.20 in case of any of the following circumstances, suspension operation shall be suspended:1., in the event of bad weather, such as heavy rain, heavy snow, fog and construction work surface has six (including six) above the strong winds, affecting safety construction.2. crane leakage occurs.3. serious wear of wire rope, to scrap standard (wire rope scrap standard see Appendix A).4. safety guards fail or display inaccurate.
Q:What are the "2 magnification" and "4 magnification" mentioned in the lifting characteristics table of tower cranes?
Popular saying: "car to hook this section of vertical distance, you see 4 wire rope is 4 magnification, you see 2 wire rope is 2 magnification.".
Q:What are the working mechanisms and safety devices of tower cranes?
A safety device: four limit: height limit, amplitude limit, slewing limit, travel limit; three insurance: luffing rope insurance, car insurance broken shaft, the hook to prevent falling insurance; two limit: torque limiter, weight limiter on these roughly.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:How to install the jack up tower crane 30How to install the jack up tower crane?
Looking for technical personnel to install, you fuck what heart?.
Q:Who invented the tower crane, please?
Tower crane originated in Western europe. The first patent on tower cranes for construction was issued in 1900. In 1905, a crane with a boom was fixed in the tower. In 1923, a prototype of modern tower crane was built. The first relatively complete modern tower crane appeared in the same year. Our tower crane started from Shanghai in 1950.
Q:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
Q:What is the difference between a tower crane and a jack up tower crane?
