Time relay is used in the L panel.

The electrical control system has many advantages, such as compact structure, reasonable layout, reliable quality and low maintenance cost etc. All electrical parts are from famous supplier at home and abroad, such as SCHNEIDER Contactor and Japanese YASKAWA Rrequency Converters etc.

We can match the components of Electric Control Panel according to customers' specially requirement. Our Panel strictly follows international universal standard, thus it can replace customers' same panel. These Panels can control 450-16000 KNM tower crane.

Specifications :

The products are according to the followlng technical parameters .

Raw material control:

1.The steel material selected 100 % comes from our natlonal large-scale steel corporations .

2.The critical materials that steel,welding material etc are all examed by chemical detection , then They are allowed into workshop for batch production.

3.Strictly conforms to drawing requirements, we make the products with 16 Manganese,40 Chromium and 45#steel etc .

4,Every parts of our products that pins ,axles,sleeves etc are strictly obey quenching and tempering procedures .

5,Every parts of our products strictly conforms to the procedure requirements : mill ,plane, polish, press ,test etc in turn.

6,As for have finished products ,we perform the requirements of theISO9001 Quality System and national standard strictly.

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 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 Siemens. The operating system is a high-quality product 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).
