The hydraulic auto-climbing formwork system (ACS) is a wall-attached self-climbing formwork system, which is powered by its own hydraulic lifting system. The formwork system (ACS) includes a hydraulic cylinder, an upper and lower commutator, which can switch the lifting power on the main bracket or climbing rail. With the power by the hydraulic system, the main bracket and climbing rail are able to climb respectively. Therefore, the complete hydraulic auto-climbing system (ACS) climbs steadily without crane. No other lifting device is needed when using the hydraulic auto-climbing formwork, which has the advantages of being easy to operate, fast and safe in the climbing process. ACS is the first-choice formwork system for high-rise tower and bridge construction.
1.Hydraulic auto-climbing formwork can climb as a complete set or individually. The climbing process is steady, synchronous and safe.
2.The brackets of the auto-climbing formwork system will not be dismantled until the construction period finished, thus saving space for the site and avoiding damage to the formwork, especially to the panel.
3.It provides all-round operating platforms. The contractors do not need to set up other operating platforms, thus saving the cost on material and labor, and improving safety
4.The error of structure construction is small. As work on correction is simple, the construction error can be eliminated floor by floor.
5.The climbing speed of the formwork system is fast. It can speed up the whole construction work (average 5 days for one floor).
6.The formwork can climb by itself and cleaning work can be done in situ, so that the use of tower crane will be greatly reduced.

Anchor system
Anchor system is the load bearing system of the whole formwork system. It consists of tensile bolt, anchor shoe, climbing cone, high-strength tie rod and anchor plate. The anchor system is divided into two types:A and B, which can be selected according to requirements.
Anchor system A
①Tensile bolt M42
②Cimbing cone M42/26.5
③High-strength tie rod D26.5/L=300
④Anchor plate D26.5
Anchor system B
①Tensile bolt M36
②Climbing cone M36/D20
③High-strength tie rod D20/L=300
④Anchor plate D20

Accessories
The hydraulic system consists of commutator, hydraulic system and power distribution device.
The upper and lower commutator are important components for the force transmission between the bracket and the climbing rail. Changing the direction of the commutator can realize the respective climbing of the bracket and climbing rail.
