Fluent supplies emergency pull cords for our conveyors and general replacement.
Reliable pull cord E-stop system for fast emergency shutdown.
Galvanized steel wire rope
3/16–1/4 inch typical
Up to 300 feet per switch
10–15 lb pull force
Die-cast aluminum or stainless steel
NEMA-rated enclosures matched to operating conditions
-40°F to 185°F (-40°C to 85°C)
1NC standard, multiple auxiliary contacts available
Manual reset lever
Optional taut-wire monitoring
safety matters most.
Pull cords use a steel wire rope that runs parallel to the conveyor, enabling emergency machine shutdown from anywhere along the system, unlike push-button E-stops that function only at fixed locations. Pull cords provide continuous emergency stop capability along the conveyor length. When the cable is pulled or cut, an internal mechanical mechanism trips, breaking the safety contact and stopping the conveyor.
Specifications vary by product, but our pull cord E-stops typically include:
Mechanical trip mechanism that remains activated even if cable is cut
Visual indication of switch status through bright flags or activation display indicators
Manual reset lever requiring deliberate action to restart equipment after emergency stop
Heavy-duty housing made of die-cast aluminum or stainless steel for harsh environments
IP65/NEMA 4 enclosure rating protecting against dust and water ingress
Independent changeover contacts for control and signaling functions
Positive shut-off design for reliable conveyor shutdown in extreme conditions
Contact configuration options, including multiple auxiliary contacts, for feedback to control systems
Cable tensioner components to maintain wire tension for reliable operation
Dual-head options allowing two-side operation for conveyors accessible from both sides
Long conveyor runs
Conveyors accessible from both sides
Continuous work zones where personnel move along the conveyor length during operation
Material jam-clearing areas where workers need immediate stop capability anywhere along the belt
Recycling sort stations and waste processing lines with personnel distributed along the conveyor
Facilities requiring OSHA-compliant continuous emergency stop access
Fixed operator control stations and monitoring positions
Control panels and electrical enclosures
Specific access points at conveyor head and tail sections
Baler infeed points and equipment interfaces
Drive unit locations and motor control centers
Limited-access areas where personnel work at defined stations
Combine both approaches for total coverage
Many facilities use pull cord and push button E-stops for layered safety protection. Install pull cords along accessible conveyor lengths and push buttons at fixed control stations, drive units, and equipment interfaces. This approach meets regulatory requirements while providing complete emergency stop access for different operational scenarios.
Install pull cord E-stops at these locations for safe operation and regulatory compliance:
Route cable 2–4 inches from conveyor edge, parallel to belt travel direction
Install support brackets every 8–12 feet to maintain cable position and prevent sagging
Position cable at accessible height: 24–67 inches above walking surface per ASME B20.1
Use eye bolts or cable guides at corners to redirect cable path smoothly without sharp bends
Mount switch housing at conveyor head or tail section on rigid structural support
Position within 6 feet of power disconnect for emergency circuit integration
Provide clear access for reset lever operation and visual status verification
Install weatherproof housing for outdoor conveyors or washdown environments
Install spring-loaded tensioner or adjustable turnbuckle at one cable end
Maintain 15–25 lb cable tension to activate switch reliably without excessive pull force
Check tension during monthly testing and adjust to compensate for cable stretch
Position tensioner for easy access during maintenance procedures
For conveyors over 300 feet, install multiple pull cord switches in series
Coordinate emergency stop circuits so activation at any point stops all zones
Use interlocking relays to prevent material flow into stopped conveyor sections
Label zones clearly and document emergency stop coverage in facility diagrams
Industrial conveyors must comply with multiple safety standards governing E-stop placement, testing, and operation. Understand these requirements to meet regulatory obligations and pass safety inspections.
OSHA mandates emergency stop mechanisms on all conveyors and references ASME B20.1 as the accepted compliance standard. Pull cord systems meet OSHA requirements for continuous emergency stop access along conveyor lengths.
Required documentation:
Maintenance and repair logs
Employee training certifications
Regular E-stop testing records
Lockout/tagout procedures
Cable tension verification records
Testing and maintenance provide reliable emergency protection and regulatory compliance. The following protocols should be combined with manufacturer and regulatory agency requirements and recommendations.
Pull cord emergency stops integrate with multiple conveyor subsystems to execute safe, controlled shutdowns. The E-stop circuit interrupts normal control logic and coordinates system-wide responses.
Pull cords interrupt power through safety relay circuits, immediately de-energizing motors to stop belt movement. The emergency stop function overrides VFD commands and removes voltage from motor starters.
For incline conveyors, controlled deceleration prevents material rollback.
Fluent supplies replacement pull cord E-stops for all of our conveyors. Our engineering team can recommend E-stop configurations, placement, and spacing for your operating environment.
E-stops are available for these Fluent conveyor types:
Fluent designs and manufactures industrial conveyors. When you purchase pull cord E-stops from Fluent, you're working with engineers who understand cable routing, tension requirements, and multi-zone coordination because we configure E-stop systems for our conveyors every day.
Whether you need replacement pull cords for existing equipment or emergency stop specifications for a new custom conveyor, our team provides technical guidance grounded in real-world safety applications.
