In trolleys and logistics trolleys, casters are relatively widely used.

Steering lock:

The steering bearing (4 or 2 locks) is locked by the spring pin, and the movable caster is locked as a fixed caster.

Anti-wrap cover:

Avoid entanglement with other materials on the shaft and the gap between the wheel and the bracket, so that the wheel can rotate freely.

Single wheel brake:

Braking device is installed on the wheel bush or caster, and is operated by hand or foot

Sealing ring:

Prevent dirt from entering the steering bearing or single wheel bearing, and keep it lubricated to facilitate rotation.

Support frame:

It is installed under the transportation tool so that it can be fixed in place.

Full brake switch:

Lock the steering wheel and the brakes that fix the wheels.

Bearing weight:

Carrying weight calculation T=(E+Z) / M
T=The weight of each caster
E=weight of the vehicle
Z=weight of moving object
M=effective load capacity of wheels

(The factors of uneven location and weight distribution should be considered)

to make sureTrolley castersThe quality and the cycle of customer use, the caster reciprocating wear test to simulate the daily use of the actual rolling, with or without obstacles test, two points are not allowed to have casters or detach from other parts during the test, and then test each caster It should be able to promote its normal function, and the rolling, pivoting or braking function of the casters after the test should not be damaged.
