2.2 FIXED BRACKET
The fixed bracket is designed to keep the wheel moving in a specific direction; therefore, it guarantees equipment directionality. Instead, equipment manoeuvrability depends on the use of swivel brackets. In general, the fixed bracket consists of a single pressed steel plate shaped into an upside-down “U”. Holes to house the wheel axle set are drilled at the bottom, while the equipment attachment holes are at the top.
