Professional Design Jumping Formwork - Hydraulic Auto Climbing Formwork – Lianggong

Product Details

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.

Characteristics

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.

Two types of hydraulic auto-climbing formworks:  HCB-100＆HCB-120

Introduction to systems of hydraulic auto-climbing formwork

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

4.Hydraulic system

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.
