Why choose climbing scaffold?
Imagine that if we build a 3-story building, in order to facilitate the peripheral construction and prevent the risk of falling, we usually do this: set up three layers of scaffolding from the ground. Each layer of scaffolding takes 1 day
What if it is a 30-story building? We have to build it layer by layer, 30 layers.
What if we want to build a 100-story building? It takes 100 layers to build it layer by layer.
That's too complicated.
So, someone designed an attached scaffold that can climb
So what are the advantages of an attached lifting scaffold?
1. Improve construction efficiency
Quick lifting: Self-climbing scaffolding can be automatically lifted and lowered through hydraulic or electric systems, which greatly reduces the time for dismantling and rebuilding traditional scaffolding and significantly improves construction speed. Lifting speed of electric hoist: generally 13cm/min. Maximum stroke per lift: one floor height. Rated lifting capacity of electric hoist: ≥7.5t, and 70kN is also available.
Synchronous operation: Multi-layer operations can be carried out simultaneously at different heights to ensure seamless connection between various processes and further shorten the construction period.
2. Enhance safety
Stable and reliable: Made of high-strength steel, and equipped with a variety of safety protection devices, such as anti-fall devices, wind speed monitors, etc., to ensure the safety of personnel and equipment during construction. Excellent fire resistance.
Safety device parameters
Anti-fall device: Gravity swing block anti-fall device, core rod anti-fall device, anti-fall distance is not more than 80mm.
Anti-tilt device: Each wall-mounted support is equipped with an anti-tilt device that is slidably connected to the guide rail.
Reduce manual intervention: The automated control system can accurately control the lifting action and reduce the risk of human error.
Control system parameters
The intelligent synchronous control device is based on a programmable single chip microcomputer and sets load information. When overloaded or underloaded by 15%, an alarm is triggered, and when overloaded or underloaded by 30%, the machine is shut down to achieve intelligent and automated control.
3. Cost saving
High material utilization rate: Since frequent disassembly and assembly are not required, the demand for a large number of steel pipes, fasteners and other materials is reduced, and the cost of material procurement and transportation is reduced.
Low labor demand: The construction process is simplified, the required human resources are reduced, and the labor cost is reduced.
Low maintenance cost: The structural design is reasonable, easy to maintain and repair, and a lot of expenses can be saved in long-term use.

4. Strong adaptability
Flexible adjustment: The position and height can be adjusted at any time according to the shape of the building and the construction progress, and it can adapt to various complex building structures.
Wide scope of application: not only suitable for new construction projects, but also suitable for old building renovation and exterior wall decoration projects.
5. Environmental protection and energy saving
Reduced waste: Strong reusability, avoiding a large amount of waste generated by one-time construction of traditional scaffolding.
Reduced energy consumption: Compared with traditional methods, self-climbing scaffolding consumes less energy during the lifting process, which helps to save energy and reduce emissions.
Whether you are a high-rise building or a low-rise building, you only need to assemble a 4.5-story scaffolding at one time, and then perform the lifting operation. There is no need to transport materials in the middle. Compared with the same ground-type scaffolding, one installation can save more than 60% of steel and more than 50% of labor. Compared with traditional scaffolding, the economic benefits are obvious.
6. Beautiful and neat
Good integrity: The appearance is uniform, which improves the overall image of the construction site and is conducive to civilized construction management.
Reduce site occupation: It occupies a small area and will not affect other construction activities on the ground, making the construction site more orderly.
In the self-climbing, the workers' high-altitude operations are turned into low-altitude confined space operations.
Therefore, the self-climbing scaffolding has become an indispensable and important equipment in modern construction with its high construction efficiency, excellent safety performance, significant cost savings, strong adaptability, environmental protection and energy-saving characteristics, and beautiful and neat appearance. It not only greatly improves the speed and quality of construction, but also contributes an important force to the sustainable development of the construction industry. In the future, with the continuous advancement of technology and the increase in market demand, the self-climbing scaffolding will continue to innovate and develop, and provide more intelligent, safe and efficient solutions for more complex construction projects. We have reason to believe that the self-climbing scaffolding will play a greater role in the future construction field and become a key force in promoting industry change.
A Closer Look at Modern Climbing Formwork Systems
Modern climbing formwork systems comprise a large wall formwork mounted on a climbing scaffold. Climbing brackets are attached to preset anchors as part of the first concrete pour. This ensures that the wind loads and dead load of the wall formwork and the brackets are transferred. The formwork also uses two climbing brackets to create a working platform to align and support the panels.
Once the concrete has been poured, suspension shoes and screws are attached. Then, both the climbing platform and the formwork are lifted to the new suspension point to be used for the next pouring cycle.
Types of Climbing Formwork Systems
Climbing formwork systems come in different shapes and sizes, all with their own unique qualities and specifications. Keep in mind that a particular type of climbing formwork may be better suited to one project over another. Because they can be very diverse, we recommend that you seek expert advice from our team here at MEVA to ensure that you receive the best possible solution for your construction project.
Self-climbing formwork
Self-climbing formwork is an automatic climbing system that is lifted without using a crane. Instead, it has hydraulic rams that lift the scaffold, formwork, and secondary formwork to the next pouring cycle. Self-climbing formwork systems, such as the ones we offer here at MEVA, are often used in the construction of tall concrete structures. These include bridge piers, towers, the cores of high-rise buildings, and other projects that require seamless walls.
Since self-climbing formwork does not require any lifting equipment, it can significantly help reduce overall costs and labor. Another advantage is that it allows builders to continue their work even when it is very windy.
Single-sided climbing formwork
Besides the crane-dependent and self-climbing formwork systems, there is also the single-sided climbing formwork where the concrete pressure that develops during pouring is transferred into the wall below through braces and wall struts instead of being transmitted into an opposite formwork through ties. Single-sided climbing formwork systems are often essential in the construction of dams, sluices, and other similar structures.
Climbing Formworks from MEVA
At MEVA, we are committed to developing climbing systems that promote maximum safety in the workplace while helping builders reduce their construction time, labor, and overall costs. As such, we provide climbing formwork systems with smart designs and features that will help you meet the specific requirements of your project and enable you to achieve your business goals.
MGC-F Climbing System
The rail-guided MGC-F is equipped with guide rails and guide shoes, thereby ensuring that the climbing formwork remains firmly anchored to the structure regardless of the prevailing weather conditions. Due to its innovative design, the MGC-F can arrive pre-assembled on-site, ready to be flown directly onto the wall. As a result, you can make the best use of space, and reduce your overall project duration and labor costs. The MGC-F is also known for its high level of safety. It features fully integrated access ladders with safety cages, allowing you to provide optimum protection for your team on the ground.
