• 2. Flexible and Reasonable Structural Design: Adopting gantry frame structure, it can span the precast beam production workshop, storage yard and construction site, realizing all-round hoisting operation without being restricted by site layout. The beam and leg structure can be customized according to the actual site size and precast beam specifications, which improves the space utilization rate and adaptability of the equipment.
• 3. High-precision Operation Performance: Equipped with advanced frequency conversion control system and high-precision positioning device, it can realize stepless speed regulation of lifting and traveling, and accurately control the lifting speed, direction and position. It can avoid collision and damage of concrete precast beams during hoisting and transferring, ensuring the integrity of precast beam quality.
• 4. Umfassender Sicherheitsschutz: Ausgestattet mit mehreren Sicherheitsschutzvorrichtungen, inklusive Überlastschutz, Hubhöhenbegrenzung, Reiselimit, anti-sway device, emergency stop button and wind speed monitoring device. It can timely alarm and cut off the power supply when abnormal conditions occur, ensuring the safety of operators, equipment and precast beams.
• 5. Einfache Installation, Disassembly and Transfer: The components are designed with modularization, which is easy to assemble and disassemble. It can be quickly transferred and reused between different construction sites, reducing the installation and transportation cost, and improving the utilization rate of equipment.
• 6. Strong Environmental Adaptability: The whole machine is treated with anti-corrosion, anti-rust and dust-proof, which can adapt to various harsh construction environments such as plains, hills, coastal areas and outdoor bad weather (after corresponding safety adjustment), ensuring stable operation in all seasons.

Technical Parameters of 80 Tonnen-Portalkran

Application of 80 Ton Gantry Crane in Concrete Precast Beams

Der 80 ton gantry crane runs through the whole process of concrete precast beam production, storage, transportation and on-site installation, and its application effect directly affects the progress and quality of the whole project. It is widely used in various links of concrete precast beam construction, and its specific application scenarios are as follows:

1. 80 Ton Gantry Crane For Precast Beam Production Stage

In the precast beam production workshop, Die 80 ton gantry crane undertakes the hoisting and positioning of key materials and components. Firstly, in the formwork installation link, it hoists the prefabricated steel formwork to the designated pouring position accurately, and adjusts the level and position through the high-precision positioning device to ensure the formwork is installed in place, laying a foundation for the forming quality of precast beams. Secondly, in the steel cage hoisting link, the 80-ton load-bearing capacity ensures that even large-scale steel cages (weighing tens of tons) can be hoisted stably, and the anti-sway device avoids the steel cage from colliding with the formwork during hoisting, ensuring the accuracy of steel cage positioning. Finally, after the concrete pouring is completed and the initial setting is achieved, Die 80 ton gantry crane is used to hoist and remove the formwork, which is efficient and safe, and avoids damage to the surface of the precast beam caused by manual formwork removal.

2. 80 Ton Gantry Crane For Precast Beam Curing and Storage Stage

After the concrete precast beams are poured and formed, they need to be transferred to the curing area for professional curing to ensure their strength and durability. Der 80 ton gantry crane hoists the formed precast beams (with a weight of 50-80 Tonnen) to the curing area smoothly, and places them neatly according to the specifications, avoiding collision between beams. After the curing is completed, the crane transfers the qualified precast beams to the storage yard for classified storage, and can stack them in layers according to the bearing capacity of the beams, saving the storage space. During the whole process, the stable operation and precise control of the crane effectively protect the integrity of the precast beams and avoid quality defects such as cracks.

3. 80 Ton Gantry Crane For Precast Beam Transportation Loading Stage

When the concrete precast beams need to be transported from the precast yard to the on-site construction site, Die 80 ton gantry crane is responsible for loading the precast beams onto the special transport vehicle. Due to the large weight and volume of the precast beams, the crane needs to coordinate with the transport vehicle to realize precise positioning and stable hoisting. The frequency conversion control system of the crane can adjust the lifting speed according to the actual situation, ensuring that the precast beams are placed stably on the transport vehicle without tilting or sliding, and ensuring the safety of the transportation process.

4. 80 Ton Gantry Crane For Precast Beam On-site Installation Stage

On the bridge construction site, the installation of concrete precast beams is the core link, and the 80 ton gantry crane plays an irreplaceable role. According to the on-site construction environment, the crane is installed and debugged, and the gantry frame spans the bridge piers to realize the hoisting and installation of precast beams. The high-precision positioning device of the crane can accurately place the precast beams on the bridge piers, ensuring the installation accuracy and structural stability of the beams. Even in outdoor environments with wind or uneven ground, the crane can maintain stable operation through the wind speed monitoring device and stable structural design, ensuring the smooth progress of the precast beam installation work.

Zusammenfassend, Die 80 Tonnen-Portalkran, with its excellent product performance, standardized technical parameters and comprehensive application scenarios, has become an indispensable core equipment in the concrete precast beam industry. It not only improves the construction efficiency of concrete precast beams, reduces the labor intensity of operators, but also ensures the construction quality and operation safety, and promotes the high-quality development of infrastructure construction projects. With the continuous upgrading of equipment technology, Die 80 ton gantry crane will be more intelligent and efficient, bringing more value to the concrete precast beam construction industry.
