Choosing Castors & Wheel Locks for Mobile Towers
When choosing castors for a mobile tower or ladder, match the wheel size and load rating to the tower and the surface it runs on, and make sure every castor has a reliable brake that locks both the wheel and its swivel. Good castors roll easily when unlocked and stay firmly put when locked - both matter for safety.
Load Rating & Wheel Size
Castors must carry the tower plus its working load; larger wheels roll better over rough floors.
Dual-Action Braking Rigs
Heavy-duty mobile scaffold castors must feature dual locking mechanisms that freeze both wheel rolling rotation and 360-degree swivel action simultaneously.
Zero Occupied Tower Movement
Never attempt to push or reposition a mobile tower while personnel, loose tools, or materials remain on upper decks. Clear the platform completely before unlocking castors.

Substrate Verification & Surface Suitability
Smooth indoor floors vs rough or outdoor ground change the castor you need.

Locking Brakes (wheel + Swivel)
The brake should lock both the wheel and the swivel so the tower can't roll or turn.
Positive Lock Engagement
Extend each rung section sequentially until the audible spring-loaded locking pawls snap firmly into place. Never climb on partially extended or unlocked segments.
Visual & Physical Verification
Physically push down on each extended section before ascending to confirm positive mechanical capture. A visual check ensures red indicator flags are completely recessed.
