Product Description
Overview
|
|
KATTOR jFP is composed of three sub-systems, i.e., bailey truss platform system, suspension system and power shoring and jacking system. |
1. Bailey truss platform system
|
Truss platform
It includes type 200 bailey truss with four kinds of length: 3m, 2m, 1.75m, 1.25m and three kinds of joints: joint 1,2 ,3. Through axis pins, primary and secondary trusses are vertically and horizontally connected and assembled to a square frame structure
|
Top steel platform
On top of the structure is the upper steel platform, and its bottom suspending the middle steel platform. The top steel platform provides a temporary storage yard for steel structures including steel bars, stiffened steel frameworks etc., and also contains material spreader, gas bottle room, waste platform, washroom and so on. |
Middle steel platform
The middle steel platform provides central control room, mixing room, material storage yard, welding machine room, power supply room and temporary rest place for workers.
|
2. Suspension system
| The upper pulley structure is used to move the suspension rack inwardly when the outside wall of the core adducts.The standard suspension rack unit provides 7 layers operation platform outside the core and 6 layers inside, to finish following works: 1.decoration of layer Fn-1 which already finished concrete casting. 2. Set up and take away formworks of layer Fn which is standing by for casting. 3. Steel bar banding of layer Fn+1 and so on. |

3. Power shoring and jacking system
|
|
. Power shoring and jacking system Power shoring and jacking system comprises upper and lower shoring box girders, Jacking cylinder and shoring cylinder, Jacking stand column, Hydraulic power system and control system.Upper and lower shoring box girders include standard segmental girder and nonstandard segmental girder. The standard segmental girder is equipped with cylinders to control the action of brackets, to realize shoring of the whole system. Jacking stand column and jacking cylinders are connected by flange, the jacking force pass to bailey truss platform system through stand column during jacking up process. Equipped with anti-falling system, the pawl sticks inside the trough and effectively prevents the whole system from falling in case of accidental cylinder slipping. Intelligent hydraulic power and control system uses closed-loop control, which set up displacement and pressure sensors, through computer control and hydraulic drive to achieve composite and sequential action, to meet the requirement of synchronous jacking accuracy of 1mm. Equipped with cameras in bracket position and stress-strain sensors in steel structure component, all of them controlled by central computer (human - machine alternation interface) to realize visual monitoring and measuring.

Core components of JFP system
1. Double acting hydraulic cylinders with long stroke, high capacity
|
Double oil cavity design, realize double acting by oil pressure, stroke of main jacking cylinder up to six meters ,large load capacity ,can afford side load up to 10% of rated load capacity. The cylinder is on the bottom of the operation platform, and it was synchronous controlled by control panel to realize stable lifting.
