General introduction of tower crane main mechanisms .

( 1 ) Main raw material of tower crane’s body and tower-cap are 16 Manganese,Q345B Steels , which are selected from heavy wall seamless steel pipe manufactured byAnsteelSteel Group.

( 2 ) Hoisting mechanism " Jiuhe " and " Yibin " brand are provided by national-level manufacturer. To adopt eddy current brake,four-speed winding hoist.

( 3 ) Slewing bearing : appointed corporation of Fangyuan Slewing Bearing Factory .

( 4 ) Slewing mechanism : equipped with four-speed winding motor and " Shengjian " brand, the quality is the same with exporting supplier " Potain " .

( 5 ) Luffing mechanism is double-speed cone rotor motor, so It’s needn't refill gear lubricant or maintenance , and double-planetary reducer.

( 6 ) Electrical apparatus system : The main contactor is from Schneider or Siemens. The operating system is a high-quality product ( Schneider integrated pellet ) ,which provided by Sanmen Sangang ,and is durable in use.

( 7 ) Welding : welding is carbon-dioxide shielded and automatic submerged arc welding. Feature: advanced technology,strong connectivity.

( 8 ) Driver cab : With arc space capsule , toughened glass , wide field of vision , clear and safe ,auto wiper, air conditioner.

( 9 ) Basic mast section : square strengthened steel, repeatedly applicable, convenient in tower crane displacement. But lower in cost.

( 10 ) Mast section : 3 meters in length , strengthened bolted with 10.9 grade high-strength bolt . each mast section with 12 bolts .( common manufacturers adopts 8.8 grade).
