What are the precautions for daily maintenance of caster brake system?

Routine maintenance of caster brake systems is crucial to ensuring braking performance, extending life, and ensuring safety (especially in B2B scenarios). Key considerations are as follows:

 

Cleaning:

Regular Cleaning: Weekly, use a dry, soft cloth or brush to remove dust, debris, and oil from the brake lever, pads, connecting shaft, and other surfaces. Oil stains can be removed with a neutral detergent; avoid using corrosive solvents.

 

Clean the Gap: Remove impurities (lint, grit, etc.) from the gaps between the brake lever shaft, brake pads, and wheel. Compressed air (low pressure) or a thin wire can be used to ensure smooth movement.

 

Lubrication:

Lubrication Areas/Frequency: Focus on lubricating the brake lever shaft, connecting shaft bushing, and spring. In normal (dry) environments, apply a specialized grease (such as lithium-based grease) every one to two months; in harsh environments (humid, dusty, and cold), apply every two to three weeks.

 

Avoid Mistakes: A thin layer of grease is sufficient; excessive grease can attract dust. Never apply grease to the contact surfaces of the brake pads or wheel, as this can cause braking failure.

 

Inspection:

Component Wear:

 

Brake Pads: Check thickness weekly (wear exceeding 1/3 or cracks/hardening require replacement) to ensure a seamless fit with the wheel when the pedal is applied.

 

Connecting Shaft/Brake Lever: Check monthly. Any play exceeding 1mm or any sticking/unusual noise requires tightening or replacement.

 

Spring/Mechanism: Check for spring slack (inability to return to the desired position) and bent brake levers, and replace them promptly.

 

Functional Test: Before each use, perform a light pedal test to ensure the brakes are sensitive (instantaneous locking) and fully return to the desired position (unobstructed rotation) upon release. If braking delay or one-sided braking is detected, immediately stop the machine for inspection.

Environment and Usage:

 

Avoid long-term use in extreme environments (high temperature, humid and corrosive conditions, rough surfaces). Select suitable materials and perform adequate maintenance.

 

Proper Operation: Overloading, violently applying the brake lever, or moving the machine with the brakes on is strictly prohibited.

Records and Replacement:

 

For frequently used equipment, it is recommended to maintain a maintenance log (including cleaning, lubrication, inspection times, and any issues encountered).

 

If the connecting shaft is broken, the brake lever is severely deformed, or the brake pad contact area is less than 50%, the entire brake assembly must be replaced.

 

Summary: Adhere to the principle of "prevention first" and ensure safety and efficiency through regular cleaning, proper lubrication, strict inspection, and standardized operation to promptly eliminate interference, mitigate wear, and identify potential hazards.
