THE CASE IS ONLY PART OF THE TOTAL LOAD

CASTOR + LOAD + GROUND + HANDLING
Simply dividing a load among four castors does not replace selection according to manufacturer specifications and actual application.
- Weigh or record the complete unit including accessories.
- Record thresholds, floor surfaces and tight turns.
- Clarify wheel design and necessary securing for the actual application.
Survey the entire route once
Walk the usual transport route and note its different sections. A smooth storage floor differs from a paved driveway. Door thresholds, ramps and small steps belong in the same description. Photographs help make these conditions understandable in an inquiry.
Also record manoeuvring space and bottlenecks. A case must not only roll straight ahead but also turn and be parked. If it goes in a lift, both the door opening and interior matter. Consider the lid configuration: perhaps it travels closed but must open in a tight position.
Calculate the complete load
The total load includes contents, case, installed parts and accessories. In selection, Blickle distinguishes factors including load capacity, the number of supporting castors and operating conditions. Simply adding the printed individual ratings is therefore insufficient for design. The actual assembly and conditions must be assessed together.
If the contents change later, loading can shift too. Document the intended equipment. A heavy extra device later placed in an empty compartment changes not only the load but possibly the centre of gravity. A wheeled case planned appropriately once should not be treated as an endlessly expandable transport platform.
Manoeuvrability is a requirement in its own right
Swivel castors can align with the direction of travel; fixed castors guide in a fixed direction. The appropriate combination depends on the task. Blickle describes arrangement, castor type and ground as factors affecting manoeuvrability. The question is therefore not only whether castors are fitted but how the case will move.
Describe whether routes are mainly straight or involve tight changes of direction. Where is it pushed or pulled, and which grip areas remain accessible? Holding points, brakes and a safe parking position belong in the discussion. The specific design should suit the loaded case and actual conditions.
Transport suitability does not end at the vehicle door
Castors enable movement on the ground. They are not a universal solution for secure transport inside a vehicle. Likewise, an ordinary case handle should not be used as a lifting attachment point without suitable capability. Securing the load is a separate task and must suit the vehicle, load and intended securing equipment.
Before the next use, inspect the castors briefly. Do they turn and swivel as intended? Are there foreign objects around the tread, visible damage or suspect fastenings? If a wheel stops unusually, clarify the cause. Do not simply pull a loaded case harder over an obstacle that already caused problems on the first attempt.
- State the complete load including case and accessories.
- Photograph ground types, thresholds and ramps.
- Measure door openings, lifts and manoeuvring spaces.
- Discuss pushing and grip positions when loaded.
- Consider parking, vehicle transport and regular visual inspection.
Good to know
Can the load capacities of all castors simply be added?
That is insufficient for design. Operating conditions, load distribution and the castors actually supporting the load must be considered.
Are high-capacity castors suitable for every ground surface?
No. Ground, wheel material, resistance and application also affect selection. Describe the real transport route.
