Tire Scissor lift crane is to increase the tire is mounted on a special chassis and axle on the composition of a fully slewing crane , the upper structure and the same crawler crane , the installation in order to ensure the stability of the body , the crane with four retractable legs . On flat ground may or may not be small outrigger from the weight lifting and hanging objects at low speed . It consists on the train and get off two parts. On the train as part of the lifting operation , with the boom , lifting mechanism , luffing mechanism , balance weight and turntable , etc. ; alight and walk part of the support . Alighting connection between the use slewing . Crane is generally required down legs , increasing the bearing surface , and the body leveling , to ensure the stability of the crane .
Tire cranes ( RTGs ) boom
Boom structure in the form lattice boom and telescopic arm two kinds . The former wire rope pulley luffing , or take a long folding arm length , the length of the larger ; latter multi-section telescopic boom box-shaped cross-section , and a luffing telescopic hydraulic cylinders . Driving conditions due to small size, the need to adapt to rapid transfer of the site . Working body can be mechanical , hydraulic and electric . Hand pallet jacks compact structure, convenient operation, easy speed control and overload protection and other advantages. Typically used for handling heavy tires hanging and installation operations, from the weight of small, may play outrigger operation , even with load walk. Has good mobility , transfers and convenient features for mobile operations , widely used. The basic technical parameters : Starting weight , lifting height , amplitude , load torque and machine weight . Tires hanging from the weight of the rated strength by the boom and the whole stability limit , with the magnitude of change , in order to prevent overloading must be equipped with torque limiter. Since traveling faster truck cranes , transfer and flexible , chassis and parts supply more convenient , etc., particularly telescopic boom truck cranes, has developed rapidly. RTG is to improve mobility and cross-country towards further development directions . Multilateral shaped cross-section telescopic boom , box-shaped radiant chassis , movable counterweight hanging tire and other new emerging .

Third, the tower structure rotation mode

Can be divided into the rotation ( rotating tower ) and turn on the ( non-rotating tower ) tower crane .
Slewing tower crane will lower slewing , etc. counterweight disposed in the lower end of the main body , and its advantages are: tower suffered few moments , low center of gravity , good stability, electrics tacker installation and maintenance , the disadvantage is more demanding slewing high mounting height is restricted.
Slewing tower crane on the slewing ring , a counterweight , major institutions are set at the upper end , the advantage is due to the tower does not turn , simplifies the tower substructure , lifting plus festival convenient. Disadvantages are: When the building over the tower height , due to the impact of the balance arm to limit the rotation of the tower crane , while the higher center of gravity , air pressure increases, the pressure weight increased , so that the total weight of the machine increases.
Fourth, the crane installed in different ways
Be able to be folded into transport, the overall self- erecting tower crane for quick installation and requires the use of auxiliary equipment for group fight and dismantling of tower cranes .
Able to set up their own fast -loading machines are small and medium under the tower slewing cranes , mainly for short duration, requiring frequent movement of low-rise buildings , the main advantage is to improve work efficiency , saving installation costs , saving time and labor and material , the disadvantage is complex structure, the amount of maintenance .
Subject auxiliary dismantling tower crane is mainly used in high-rise buildings and a large range of work , lifting a large quantity of places, is the construction site of the main types .
Five , according to whether the structure of the spire
Can be divided into flat and Pallet stackers tower crane tower crane .
Flat top tower crane is developed in recent years a new type of tower crane , which is characterized in the original jack-up tower crane structure before and after the abolition of the spire and its rod section boom enhances the structural strength and balance arm , arm and balance arm is directly connected , its advantages are: 1 , the whole small , easy to install safety, reduce transportation and storage costs ; 2 , boom tolerated good performance , force uniform, and connecting parts of the structure damage to the small ; 3 , part design standardized, modular , interchangeable , reduce equipment idle , improve investment efficiency , the drawback is the same type of tower crane tower crane Zhongping head slightly higher price .
