Double-castor launches
Blickle has released a new flagship product in its heavy duty castors range – the welded steel heavy duty double-castor, LSD-GSPO 500K with a load capacity of up to 30 tonnes.
It is equipped with heavy duty compressed cast nylon wheels, which offer low rolling and swivel resistance, especially on smooth floors. In addition to its compact design, the heavy duty castor sets itself apart through extremely high rigidity. The swivel head used here is particularly robust and has a four-point swivel bearing.
Typical fields of application for heavy duty wheels and castors include rack feeders and industrial trucks as well as assembly and transport systems. In order to ensure that the transport runs smoothly, without shocks, and that the goods reach their destination without being damaged, spring-loaded castors are also available. These provide excellent spring and damping characteristics and are specially designed for the respective application. To be able to absorb particularly heavy loads, Blickle offers castor versions with multiple wheels. Blickle also has products with load capacities of up to 50 tonnes in its standard range of wheel products. Upon customer request, solutions can be created that are specially tailored to the respective application.
“For heavy duty applications, we continuously encounter the challenge of combining very high load-bearing capacities with a compact design,” reports Thomas Zimmer, head of the heavy duty wheels design department at Blickle. “Our customers attach great importance to a high level of operational comfort. That is why we are seeing the trend moving away from steel and cast wheels and toward wheels with polyurethane tread, which also helps protect the floor surface.”
Using the finite element method (FEM), the designers simulate the overall behaviour of the final product, taking into account various influencing factors such as the condition of the surface. This allows them to optimise the product for its intended use from the very earliest stages of the development process.
Heavy duty castors can be used for fine positioning. One example of this are the welded steel Blickle LSD-SETH heavy duty castors, special versions with an extended axle for fine positioning of the tripod jack under the aircraft, used on the HYDRO tripod jack with a capacity of 110 tonnes.
As an industry leader, HYDRO has been developing products and projects for the production and maintenance of aircraft and engines for more than 50 years. In the area of ground support equipment, the company's tripod jacks enable particularly economical and highly-efficient aircraft maintenance, covering the entire spectrum of aviation with a capacity of between two and 210 tonnes. "Our customers tow our tripod jacks over long distances and at high speeds, sometimes over poor surfaces to their place of work," says Pamela Lanzillotti, head of Business Unit Ground Support Equipment at HYDRO. “That's why we were looking for special castors with low rolling resistance and ended up developing a special suitable solution with Blickle.”
