Define the danger zone
Movement, direction, force and credible body-part access are mapped before the protective boundary is set.
In-running nip and trapping protection
Conveyor Nip Point Guards
Purpose-designed guards that prevent reach to in-running nips at drums, rollers, belts, chains, transfers and return paths without obstructing normal product flow.
Physical guarding first · emergency stop is supplementaryDirect answer
A conveyor nip point is a trapping or drawing-in zone where moving parts converge, such as a belt meeting a drum or roller. Effective nip-point guarding makes the danger zone physically unreachable from above, below, through and around the guard while preserving safe operation and maintenance.
Hazards and access
Find every approach to the nip—not only the obvious one.
A close-fitting guard can still fail if someone can reach around its end, underneath it or through an opening. Surveying the full reach route is essential.
- 01Belt-to-head and belt-to-tail drum nips
- 02Return belt and idler roller nips
- 03Powered roller and transfer interfaces
- 04Chain, sprocket and toothed-belt drawing-in points
- 05Angle changes, merges and diverters
- 06Reach around guard ends or from nearby platforms
Application-led engineering
Geometry, distance and access considered together.
Close every reach route
Aperture, stand-off, end extension, floor clearance and surrounding structures are reviewed as one geometry.
Keep intervention safe
Cleaning, adjustment and jam clearance must use isolation or controlled access—not routine reach past the guard.
Plan the right solution
Why an emergency stop cannot replace a nip guard.
An emergency stop reacts after a person identifies danger and operates the device. A fixed or suitably controlled guard prevents access in the first place. PUWER’s hierarchy starts with fixed guards where practicable.
HSE guidance states that work equipment users must take effective measures to prevent access to dangerous parts. Where routine access is required, interlocked guards—and sometimes guard locking—may be needed so dangerous movement stops before the person can reach it.

Typical project scope
From hazard schedule to installed guard.
The work can address one high-priority nip or map the complete conveyor route so gaps are not left between individual upgrades.
- Nip-point and reach-route survey
- Prioritised hazard schedule
- Fixed, removable or interlocked guard design
- Material and fixing specification
- Manufacture and installation
- Reach, fit and access checks
Questions buyers ask
Conveyor Nip Point Guards FAQs.
Clear answers for early planning; the machine-specific assessment determines the final safeguarding arrangement.
What is an in-running nip on a conveyor?
It is a point where a moving belt, roller, chain or other component converges with another surface and can draw in fingers, clothing or a body part.
Does a conveyor emergency stop remove the need for guarding?
No. Emergency stops are supplementary. They do not prevent initial contact or guarantee that movement stops before injury occurs. Accessible dangerous parts still require effective safeguarding.
Can a small gap still be dangerous?
Yes. Finger or hand access may exist through a small opening, and reach depends on the aperture, stand-off distance and surrounding geometry. These factors must be assessed together.
Can nip guards include inspection access?
Yes. Inspection windows, tool-removable panels or monitored access can be incorporated when the task and stopping behaviour are understood.
