( 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 by Ansteel Steel 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
( 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.
steel pretreatment
steel cutting and blanking
machining operation
Blended welding

Components description
Mast: the main supporting tower of the crane. It is made of steel trussed sections that are connected together during installation.
Slewing unit: the slewing unit sits at the top of the mast. This is the engine that enables the crane to rotate.
Operating cabin: the operating cabin sits just above the slewing unit. It contains the operating controls.
Jib: the jib, or operating arm, extends horizontally from the crane. A "luffing" jib is able to move up and down; a fixed jib has a rolling trolley that runs along the underside to move goods horizontally.
Counter jib: holds counterweights, hoist motor, hoist drum and the electronics.
Hoist unit: the hoist unit houses the hoist drum, hoist cable, gear box, gear shift, brake, and supporting components.
Hook: the hook (or hooks) is used to connect the material to the crane. It hangs at the end of thick steel cables that run along the jib to the motor.
Weights: Large concrete counterweights are mounted toward the rear of the mast, to compensate for the weight of the goods lifted.
