  • Classification tower crane according to installation methods 2015/8/13 According to installation methods,tower crane have Fast-loading crane, self-elevating tower crane and inner climbing tower crane.⑴ fast-loading crane itself with special towing and erection equipment, boom and tower can be folded together to achieve the overall haulage; to the site, but also it will soon be erected, so it should be more precise called overall haul quick installation of the tower crane.⑵ from one tower lift tower crane is pieced together by the st...
  • Basically has the following several kinds of common reinforcement methods 2015/7/30 During the time the tower crane installation, you need to calculate the bearing capacity of the foundation, if the foundation bearing capacity can not meet the design requirements of construction elevator, we need to reinforce the foundation, strengthening methods commonly used are the following:1, the general treatmentUsually by compaction method, drainage consolidation method, soil replacement cushion method, vibratory compaction compaction method. Among them, soil...
  • Tower crane hoisting height regulations have 2015/7/29 Lifting height also called hook height is the vertical distance from the surface of the concrete foundation of the tower crane to hook. On the trolley tower crane, its maximum lifting height is immutable, the pitch luffing tower crane, its amplitude varies with different lifting height, lifting height than the minimum amplitude high top tens m, so the pitch luffing tower crane has an advantage in starting the lift. Tower crane lifting height includes two parameter...
  • Introduction for tower crane 2015/7/27 Tower crane is a tower upright, the boom is hinged at the lower tower caps, can rotate 360 ° crane, commonly used in building construction and equipment installation, with a wide scope, from the high rise, big turning radius, work high efficiency, easy operation, reliable operation and so on. Tower cranes with lifting, vertical transport and short horizontal transport functions, are widely used in building construction, especially for high-rise construction, ...
  • Tower crane hoisting height 2015/7/23 Tower crane lifting capacity varies with amplitude. From the weight of the product and the magnitude of the load torque is called, it is the main technical parameters of this crane. By rotating mechanism and slewing tower crane lifting height, large inertial mass turn and walk, it needs to have good speed performance, particularly the lifting mechanism required to light load fast, slow reload, install it Bit jog. In addition to using resistance governor general, but ...
  • Safety control points for tower crane 2015/7/22 1. The tower crane must address the characteristics of its type, the specification of the technical requirements before installation and removal, combined with the operating conditions to develop a detailed construction plan.2. Tower crane installation and disassembly operation must by obtain corresponding qualification, professional team of installation experience qualified, has issued by the relevant government department in charge of the certificate shall ap...
  • Limit device for tower crane 2015/7/16 1. From the weight limiter, also known as overload limit position, is a can make the crane overload safety device, when the hoist weight exceeds the rated lifting weight, it can automatically cut off the lifting mechanism of power supply parking or alarm. Lifting limiter has two kinds of mechanical and electronic.2. Moment limiter for tower crane, to a certain extent only allow lifting a weight lifting, if you are overweight, attention is turned dangerous inclination...
  • The working principle and application of building hoist 2015/7/10 Hydraulic building hoist platform products in accordance with the work divided into Boom hydraulic building hoist, hydraulic building hoist, Mast pole hydraulic building hoist, hydraulic building hoist arm . Hydraulic hoists are folding arm lifts ( lifting platform ) , scissor hoists ( lifting platform ) replacement. It can be widely used in railway stations, docks , airports, hotels , telecommunications, municipal gardens , grain storage, cleaning companies, public ...
  • Performance for heavy tower crane 2015/7/9 Heavy tower machine is intermittent operation of the machine, with a short and duplication features. When work stopped when the institutions open , sometimes forward , sometimes reversed. Some cranes work day and night in three shifts , some only work group , or even a days work only a few times. Such working conditions show : namely the use of different grades of different heavy tower crane tower crane and heavy-duty work in different organizations busy . While the ...
  • The operation of the building hoist without careful maintenance 2015/7/8 Building hoist in the process of buildings, roads, bridges and other construction and provide material to carry a device, which can effectively accelerate the construction progress, save engineering time, reducing expenses and more economical. The use of any machinery are inseparable from the proper maintenance, building hoist is the same, correct operation and careful maintenance is to ensure construction lifting and work performance and prolong its service li...
