A Complete Analysis of Caster Wheel Fixing Methods: Matching Scenarios and Practical Guide

Time：Aug 19,2025

In scenarios such as logistics turnover, warehouse management, and cargo transportation, casters are indispensable moving parts, and the choice of their fixing method directly affects the efficiency and safety stability of the equipment. To meet diverse working conditions, casters have developed a variety of fixing technologies. The following is a detailed introduction to common types:

Bolt Fastening: Basic and Stable Rigid Connection Bolt fastening is a fixing method that directly locks the caster to the equipment base through threaded fasteners. This structure uses an internally threaded sleeve or externally threaded rod combined with a matching nut. The installation process is simple and convenient, and it can form a high-strength rigid connection. Its core advantage is its outstanding stability, which is suitable for scenarios with low movement frequency but high load-bearing requirements, such as heavy-duty industrial machine tools and auxiliary mobile devices at the bottom of fixed storage shelves, which can effectively prevent equipment from displacement when stationary or moving at low frequencies. ## 2. Shaft Connection: Load-bearing Enhanced Power Adaptation Shaft connection achieves fixation by directly connecting the center axis of the caster to the transmission structure of the equipment. It is a connection method designed for heavy loads. This technology can rigidly combine the caster with the load-bearing frame of the equipment through mechanical structures such as gear meshing, pin insertion, or cotter pin fastening, ensuring power transmission and load-bearing balance. This type of fixing method is widely used in industrial handling vehicles, large trolleys, and other equipment that requires frequent start-stop and steering, and can maintain the synchronous movement of the caster and the equipment under heavy load conditions, avoiding safety hazards caused by loose connections.
Braking Integrated: Flexible Control of Dynamic Start and Stop Braking integrated fixing achieves instant fixation during the movement process by adding a braking mechanism to the caster body. Its braking components are divided into foot-operated brakes (locking the wheel body by linking the brake pads through the pedal), manual knob brakes (rotating the screw to press the friction plate), and automatic induction brakes (combining sensors to achieve stop-in-place), and other types. This design gives the equipment the flexibility of temporary fixation, and is especially suitable for tools such as trolleys and logistics turnover boxes that require frequent stops for loading and unloading, which can not only ensure the smoothness of movement, but also quickly lock the wheel body during operation.

Four. Ground Brake Support: Static Stable Suspended Fixation The ground brake support type achieves equipment fixation through a braking device independent of the caster: when the ground brake is activated, its support structure will lift the equipment body upwards, so that the caster is completely off the ground and suspended, and the rigid support of the ground brake is used to replace the caster's load-bearing. This method can maximize the stability of the equipment when it is stationary, and is suitable for equipment that needs to be fixed for a long time, such as large storage cages, temporary transfer platforms, etc., which can avoid equipment displacement caused by uneven ground or slight collisions. Different fixing methods have their own technical characteristics and applicable scenarios. In practical applications, it is necessary to comprehensively select the fixing method based on factors such as the load-bearing weight, movement frequency, and operating environment of the equipment. By scientifically matching the fixing method, it can not only ensure the flexibility of equipment movement, but also improve the safety and stability when it is stationary, thereby optimizing the overall efficiency of logistics transportation and warehouse management.
