DoLast® lifts! Custom hoists shorten production time.

The optimization of production processes is playing an increasingly important role for companies. More efficient and safer processes can provide decisive competitive advantages. For an internationally active manufacturer of compaction equipment, we have developed an electric frame lifting device that has enabled an important work step to be reduced to a tenth of the original time.

Motors with different sizes and numbers of suspension points as well as different centers of gravity are used in the production of machines for compacting soil, asphalt and waste. As the installation angles can vary depending on the type of machine and there is also little space available, the motors need to be positioned precisely in advance.

Previously, lifting beams (Link) with several suspension points and different chain lengths were the method of choice. However, depending on the motor and device type, these had to be converted manually so that they were correctly aligned for the lifting process of the components - a time-consuming process of at least ten minutes.

With the newly designed DoLast® frame cross beam with 3- and 4-point suspension, the same process is reduced to just one minute! It can be flexibly programmed for all motor dimensions and installation angles via touchscreen and leads to a much more precise alignment of the components to be installed. After the traverse chains are attached to the motor, it is lifted but initially hangs at an angle due to the off-center center of gravity. To align it for installation, the desired installation angle is selected on the remote control. The traverse, which is equipped with a position sensor, then automatically aligns itself horizontally and vertically so that the motor can be used. Fast, faster, DoLast®.

"Artful use" with DoLast®.

What do Plexiglas spheres have to do with extreme deep-sea dives or free-floating swimming pools with Dolezych? Quite a lot when it comes to maximum safety.

Heinz Fritz GmbH from the Swabian town of Herbrechtingen processes plastics into high-quality finished parts that are used, for example, for XXL aquariums in zoos or as machine covers. Before the objects reach their final state, they have to be repeatedly lifted and turned during the machining process. And this is where we come into play. Depending on the raw material, the value of the plastic can be as high as the price of a luxury car. This makes it all the more important to ensure optimum safety when lifting and transporting the materials.

Our DoLast® spreader beam with round slings was used for the art object “Zephyr” by Kuwaiti artist Monira Al Qadiri to make working with the sensitive works of art easier and safer. The five largest illuminated acrylic sculptures in the world, which depict plankton magnified approximately 20,000 times, then had to be transported safely to Doha (Qatar). There they can be viewed in a permanent exhibition. With object dimensions of around 3 x 2.5 meters, thicknesses of up to 900 mm and off-centre centres of gravity, a great deal of skill was required.

300 Tons on one Lifting Beam: Easy Lifting with DoLast®.

A huge coke-processing machine - a so-called filling wagon - is to be shipped as a whole via Brussels to Marseille. The task for us in Dortmund was to construct a lifting beam that could lift the charging wagon, which was roughly the size of a small house and weighed around 300 tons. Our designers gladly accepted this challenge. The size of the lifting beam is just as impressive as the machine being lifted. We were on site for the test lift: Within a morning, the lifting beam was attached, including the gigantic load, and it was up and running: smoothly and reliably - a successful test lift!
