Our range launching girder is an important machinery for building high rise constructions, bridges etc. These launching girders can handle cat-in place concrete, as well as prefabricated elements, hence they are highly adaptable for varied spans and types of superstructure. with sophisticated design & fabrication, these launching girders are itself a steel structure, which moves forward on the high rise constructions or the bridge piers span by span. with varied launching capacities and heights, our range of launching girders are made using quality material, ensuring durable and reliable performance.

Launching cranes are widely used in the following applications:
1. Bridge construction
2. Highway construction
3. Railway construction
4. Road construction.

Design features include:
1. Reliable performance
A) Apply the latest separate pinned structure of triangular space truss to main girder, so as to improve the stiffness and strength of whole crane.
B) Main girder is made of Q345 high strength steel, and melt into the latest design to ensure the main girder can work under high strength mode safely.
C) ZHONGJIAN brand launching crane is pioneering in continuous one time operation during bridge launching progress in China. It is of the most complete function launching crane for single machine domestically.
D) Compared with similar products from other supplier, ZHONGJIAN brand launching crane have its unique design concept to the most difficult hole-span during bridge erection, in the way of laying side beam. So, it is safer to operate under high difficult and risk condition.

E) Powerful front, middle beam and three transom crane connect together to ensure transverse stability during bridge erection fully.
F) There is separate stroke switch control to each traveling mechanism, so as to decrease mutual collision between each traveling mechanism.
G) Overload resistance system: There is high performance weight limiter on two sets of trolleys, so if the lifting girder is overloading, the weight limiter will stop it at once.
H) There are normally three legs from other supplier. But we have four legs, including one front leg, one middle leg, one rear leg and one temporary leg.
I) Apply inner shrink leg to one time erect side beam in position and have more safety.

2. More powerful corrosion resistance
A) Strictly execute standard painting process to ensure blasting and painting quality.
B) Apply H steel enclosed section for main girder chord. Web chord is made by customized square tube to realize enclosed welding, which can avoid inner rust.

3. Higher working efficiency
A) There is traveling rail together with main girder, trolley and longitudinal crane. So, it is no need to lay traveling rail more. In this way, a lot of auxiliary materials are saved and production time is also saved.
B) ZHONGJIAN launching crane has higher working efficiency, with 6~8 pieces girder erection every day, based on enough concrete plate supplying, skilled operator and good condition at site.

4. More flexibility
A) It is symmetrically designed. Two way girder erection can be realized without split and slewing at original place.
B) Use one meter of hydraulic jack for front leg and rear leg. This design improves working efficiency, safety and flexibility largely.
C) Erect skew bridge by inclined way. Apply rotary face flange to connect each mechanism and structure, to erect 0~45° Skew bridge. Side beam can be positioned one time for over 320m curve radius bridge.

5. Easier assembly and disassembly
A) Each structure is connected by pins and bolts to facilitate assembly.
B) Normally one set of launching crane can be assembled within 7days.

Cut To Length Line Machine

Process

The sheet is processed in the following steps: decoil the raw material, feed with a fixed length via the servo motor, shearing it with various shearing tools into sheets of various types according to the drawing and then piling them on the stacking table via the conveying mechanism and the arranging mechanism.

Functional features:

1. This device can complete automatic production of various sheets for laminated, Full tapered seam cores.

2. Shearing power: imported electrical servo control technology is adopted, so the device is featured by high speed, low noise and long life.

3. Feeding power: adopt high torque AC synchronous servo motor, so has characteristics such as rapid response, high positioning and accuracy, low noise, low braking thermal loss and long life.

4. Track positioning: the centralized positioning is achieved by dragging the linear tracks of the ball screw with a servo motor. So the positioning is rapid, accurate and convenient and the track width can be memorized automatically.

5. Movement control: advanced PCC control and ethernet powerlink communication technology is adopted, reducing greatly wiring and imporving the reliability, stability and real time of the system remote control and trouble diagnosis can be achieved via the above control and technology, shortening the maintenance time and reducing the cost to the largest extent.

6. Arrangement mode: the backward pushing arrangement mde is adopted and long sheets can be arranged orderly with low vibration, reducing the orientational permeance of the processing process on silicon steel sheets to the largest extent.

7. Life guarantee: standard components of the device are imported quality ones. High accuracy of processing and assembly of basic components extents the service life of the device to the largest extent.

8. This device is a high techmechanical, optical and electrical integrated product with multiple patented technologies, it represents high manufacture level of domestic transverse shear lines and can substitute imported products, saving much outsourcing fund. Some models have automatic cut in cut become column functions.
