Freight lift with a 4000kg load capacity: Roller doors & shaft scaffolding
An Austrian industrial customer approached us with a demanding challenge: A customized freight lift, which can reliably and safely lift heavy loads to a higher level within the production hall.
Specifically, the lift must be able to transport a load of up to 4000 kg to a height of 3700 mm. To meet the customer's requirements, the platform was generously dimensioned: with an area of 3200 x 3000 mm, it offers enough space to transport up to six pallets simultaneously.
The order included not only the lift itself, but also the construction of the entire self-supporting shaft system including the automatic roller doors at the stops. The shaft was clad in durable trapezoidal sheet metal that meets both the high load requirements and safety standards. Our solution enables the customer to move heavy goods efficiently and safely, while significantly optimizing internal processes.
With this project, we have not only created a technically sophisticated solution, but also made an important contribution to increasing the efficiency of our customer's production process.
Planning and offer basis of the freight lift
The start of the project was identical to all previous lifting table projects. The customer sent us his detailed plan, including a 3D model of the desired structure and photos of the existing structure.
After some changes and adjustments, we were able to offer the ideal product and implement it together with the customer.
The assembly requires the highest precision and experience
To minimize assembly time on site, many components were pre-assembled in the factory. Complete pre-assembly as with smaller column jacks was not possible due to the size.
The individual components were already loaded onto the truck so that they could be unloaded and installed in the correct order.
Our technicians attached the parts to the crane, and the customer's crane operator lifted them into position with millimeter precision. Once in position, the parts were secured, fastened, and detached from the crane.
The assembly took 4 working days with 3 men.
Safety logic & roller doors in operation
The photo shows the goods lift for heavy loads at the lower stop with the roller door open. The roller doors open automatically as soon as the lift has reached the corresponding station. The lift only starts moving again when all doors are properly closed.
In the background, at the very top of the picture, you can see the roller shutter of the upper stop.
The two lifting columns are located to the left and right of the platform. The platform is attached to these columns. When the cylinder of the columns extends, the platform in the middle is lifted. The lifting principle is similar to that of a forklift mast.
A fixed railing is mounted on both sides of the mast, and double-leaf swing gates are mounted on the two loading sides. These gates on the platform must also be closed so that the lift can start.
Overload load test during acceptance by an authorized civil engineer
For standard scissor lifts, the load test is already carried out in the factory, before delivery.
For goods lifts that can only be assembled on site, this test must take place on site. After assembly, commissioning and the corresponding adjustment runs, the goods lift is loaded with a load. This load must be provided by the customer.
In our case, the freight elevator has a load capacity of 4000 kg, therefore a test load of 4400 kg – 10% overload – was placed on the platform. Subsequently, test runs and test measurements were carried out by the civil engineer.
After successful testing, the system was handed over to the customer in operation.
