FAQ

Q: Does it absorb vibration?

A: No. It has no spring or elastic suspension.

Q: What's the difference between 80I-E and 80I-T?

A: 80I-E is side/edge brake (wheel lock). 80I-T is total brake (wheel + swivel lock).

Q: Can four casters support 1600kg?

A: Theoretical total is 1600kg, but we recommend safety margin and even load distribution on flat, clean floors.

Q: Is it for scissor lifts?

A: No. Scissor lifts need shock/impact consideration and often different steering/locking geometry.
