Biomed story songHospital bed casters and brakes
Wheel Lock Blues
A bed that pulls to the left: hair wrapped on the axle and gunk in the brake pin. Clean it, lube it, test it.
A biomed story song from our shop-floor series. Diagrams are simplified to tell the story; this is not a service procedure, so always follow the manufacturer's instructions and your facility's policy.
The story behind it: Hospital bed casters and brakes
Hospital beds and carts roll on casters that pick up hair, thread and debris from the floor. Over time that material wraps around axles and works into swivel joints and brake mechanisms, making a bed hard to steer or a brake that does not hold.
The song's repair follows the usual approach: tag the bed and get a spare for the patient area, tip the caster up safely, clean out the axle and the brake pin, lubricate the pivot points the manufacturer specifies, and test that the bed rolls straight and the brakes lock before returning it.
