Lifting concrete stairs
“Precision work down to the millimeter”
Lifting and installing concrete stairs
Components to lift:
- 4 concrete stairs, each weighing 3500 kg
- 2 concrete stairs, each weighing 6000 kg
Required equipment from NarrowLifting:
- Spider crane C10
- Heavy-duty truck crane
- Transport rollers (tanklets)
- Lifting frame
- Plastic road plates
- Chain hoists / machine lifts / trolley beams
- Dolly TC1 carrier
How we got the job done
By combining our equipment, we’re able to move large and heavy machines with ease. Beyond transportation, we also handle machinery relocation. For moving and relocating machines, several factors are crucial: after thorough preparation—including drawings, structural calculations, and setting up the lifting frame—we finally got to the actual work: LIFTING! First, we applied a protective layer to the finished floor to shield it from scratches and damage. Next, we laid plastic road plates on the floor and brought in the equipment needed for the stair installation.
Using the Hoeflon Spider crane C10, we assembled the lifting frame and began lifting the stairs into the building—an exercise in precision. The concrete stairs, each weighing 6 tons and 2 meters wide, had to fit through the building’s entrance, which was 2 meters and 2 cm wide. This meant the work had to be carried out with utmost precision, leaving only 1 centimeter of space on either side of the stair.
Transport and Installation
Once inside and resting on our transport rollers, we moved the stairs through the building to the desired location using our Dolly D12 as the pulling vehicle. Upon reaching the location, we started the lifting process with our lifting frame, chain hoists, and Spider crane. Precision was key since the stairs wouldn’t be covered afterward, making it essential to avoid any damage. This process was repeated 5 times, providing custom lifting solutions for the building. Using a large telehandler wasn’t feasible for this project. Employing a large telecrane would have meant laying 1000 meters of dragline mats to reach the site, significantly increasing costs for the client.
The Big Float, with its 1.50-meter high tracks, easily accessed the location and operated on site. It navigated the adjacent ditch without difficulty and stayed afloat once in the water. With the C10 Spider crane, materials were handled and prepared for installation on the shore. Everything was prepared and handed over to the Big Float, allowing it to stay afloat and ensure a smooth installation process.
