Crane Classification Model: Crane Classification Model Pumping lifting equipment technical tests : Pumping lifting equipment technical tests 1, the pump station should be located lifting equipment, its rated capacity should be determined based on the total weight of the heaviest lifting parts and spreader . Lift crane height shall meet the requirements of installation and maintenance crew . 2 , since the weight is equal to or less than 5, t, the main pump station number is less than 4, the units should use electric single girder gantry crane ; starting weight greater than 5t, when should use electric single girder or double girder cranes. 3 , crane work system should take light level , slow . Duty brakes and electrical equipment should be intermediate . 4 , Crane span differential should be 0.5, m, selection, crane rail ends should handicapping feeder . 5 , pumping stations can be configured to detect and repair a simple tool . 6 , pumping stations can be properly configured for auto repair and installation , manual hoists and jacks lifting and transport equipment . Different models of tower cranes and what classification : Different models of tower cranes and what classification Referred tower crane tower crane . According to their different tower types , the following classification. ( 1 ) by structure type ① fixed tower crane : By connecting piece to the tower base frame fixed to the foundation or structure , conduct tower crane lifting operations. ② mobile tower cranes : a running device , you can walk the 15 ton overhead crane . Depending on the operation of the device , can be divided into rail , tire type , crawler . ( 2 ) according to the type of rotation ① slewing tower cranes : slewing tower is set in the upper part of the tower crane . Can be divided into tower cap rotary , rotary tower , on a rotating platform type , turn -column form . ② slewing tower cranes : slewing ring provided at the bottom of the tower , the tower rotates relative to the chassis tower cranes . ( 3 ) according to the method of erection ① non- self- erecting tower crane : relying on other lifting devices are assembled into a whole set of tower cranes . ② self- erecting tower crane : relying on its own power plant and transportation agencies to achieve the status of tower cranes and working conditions of mutual conversion. ( 4 ) by way of Change trolley tower crane : Lifting trolley runs along the conduct luffing jib tower cranes . ② boom luffing tower crane : luffing jib for the pitching motion of the 100 ton crane for sale . ③ folding jib tower cranes : the job required lifting , tower crane boom can be bent . It can also have the performance and trolley boom luffing of .
