Product Description:


1) Double main girder andtwo-span structure, more secure, faster. Applicable to the low pier andclearance under bridge is not demanded. Simple construction, needless todismantle the main girder and outside mould parts;

2) Outside mould system opens and closes transversely,original design and ingenious conception;

3) Transverse movement and hoisting is propelled bythe power, easily and fast;

4) Lifting and opening, closing are controlled by thehydraulic pressure, with steady movement which is secure and reliable. Reducethe labor intensity and upgrade the construction efficiency;

5) All the legs can pass through the whole automaticallyand erect, reducing the investment of auxiliary equipments, reducing theconstruction cost.
