Two SNHD Overhead Cranes for Slovenia Metal Processing Plant
Recently in Slovenia, a client placed an order for two units of the SNHD Single Girder Overhead Crane. The customer owns the company and has knowledge of overhead cranes. The factory was operational; thus, the equipment would have to be tailored to the existing building and not be based on a standard set-up.
These include one 3+3 tons SNHD crane with European wire rope hoist and one 2 tons SNHD crane with European electric chain hoist.
The Customer Already Had the Workshop Ready
The first crane has a 14.58-meter span and a 4.362-meter lifting height. The two 3-ton hoists can be operated separately or together. The customer selected three control modes: A, B, and A+B. This gives him the option to use either hoist independently or operate both at the same time when the lifting task requires it.
The customer had already installed 50 × 20 mm crane rails in the workshop. We therefore needed to make sure the new crane would work properly with the existing running system.
The second crane has a much smaller span of 5.55 meters and a 3.262-meter lifting height. It uses a 2-ton European electric chain hoist. The installation space was particularly tight, with only 350 mm available.
That 350 mm figure became one of the key points of the project.
A Small Installation Space Changed the Design
The customer sent us details of the existing end carriage and main beam connection in his workshop. Instead of choosing a standard 2-ton crane and hoping it would fit, our engineering team reviewed the existing structure and used it as a reference for the new design.
This was important because the crane had to work within the space already available in the factory. There was little room to make changes after installation.
The 2-ton crane also uses a 6 mm² conductor bar system with a 20-meter length and one current collector. The larger crane includes a 10 mm² conductor bar with a 14-meter length.
These details were discussed together rather than handled separately. The customer wanted to know that the complete system would work as one setup.
The Quotation Went Through Several Changes
After receiving our quotation, the customer did not simply accept the original configuration. He came back with comments, suggested changes, and questions about the equipment.
We revised the proposal several times and explained the technical points in a practical way. Since the factory had already been built, the customer was focused on whether the cranes would actually fit the workshop and match the conditions already on site.
The discussions covered the existing rails, beam and end carriage connection, available installation space, control modes, and electrical supply.
This took some time, but it also gave the customer a clearer picture of what he was buying.
Selected After Comparing Several Suppliers
The customer was considering several suppliers for the project. After reviewing the different proposals and discussing the details with us, he decided to place the order with SEVENCRANE.
The agreed production time is 20 working days. The shipment will be handled by sea under EXW terms.
For this project, the important part was not making the crane fit a catalog page. It was making the crane fit the customer's factory.
The 3+3-ton SNHD Single Girder Overhead Crane had to match the existing rail system and provide flexible control of the two hoists. The 2-ton crane had an even tighter requirement, with only 350 mm of installation space.
After several rounds of technical communication and configuration changes, the customer was comfortable with the final design and chose our solution.
For an existing metal processing plant, those practical details matter. A crane may have the right lifting capacity on paper, but the real test is whether it fits the building, works with the existing structure, and makes sense for the way the customer handles materials every day.
