The manufacturer uses bolt hole swivel castors for mobile workbenches, drawer cabinets and mobile workstations. The modular mobile tool cabinets can be individually configured by the end customer. Because of this versatility, the tool cabinets come in a wide range of weight classes and provide a wide range of load-bearing capacities. Depending on how the end customer uses the workbench, the castors can be configured so that they are placed under a constant load, or capable of handling obstacles like thresholds or expansion joints.
The customer was not satisfied with a competitor’s castors, which had a wheel diameter of 100 millimetres. These castors used a standard grey non-marking solid rubber wheel, and had a limited load-bearing capacity while still having a relatively high level of rolling resistance. The rubber tread frequently deformed under heavy loads, drastically reducing operational comfort.
