Conveyor Drawbridge
Overview
Industrial Kinetics’ Pallet Conveyor Drawbridge systems are engineered to create safe, controlled openings in pallet conveyor lines for forklift traffic, operator walk-throughs, and production line crossings. When closed, the drawbridge functions as an integral section of the conveyor, maintaining pallet flow and elevation continuity. When opened, it provides a clear, unobstructed crossing while positively securing the conveyor in a safe position.

Specifications
| Feature | Specification |
|---|---|
| Conveyor Deck Types | Multi-strand chain conveyor deck (RC60 or RC80 chain typical); Chain-on-bar construction; Chain Driven Live Roller (CDLR) deck available |
| Bridge Construction | Heavy-duty welded steel frame construction; Formed or structural steel base weldments; Designed for floor-mounted or pit-mounted installations |
| Lift and Actuation | Hydraulically actuated lift cylinders; Intermittent-duty operation; Counterbalance valves for controlled raise and lower motion; Adjustable flow controls for lift speed regulation |
| Drive and Power | Shaft-mounted or end-driven chain conveyor drive; Integral gearmotor with parallel shaft or worm reducer; Typical motor sizes around 1.5 HP (application dependent); Conveyor speeds commonly around 35–60 FPM |
| Locking and Safety Features | Hydraulic safety pin assemblies; Manual safety pins with lock-out tabs; Optional shot pin locks for positive mechanical positioning; Rubber bump stops and mechanical position stops |
| Finish and Materials | Painted carbon steel construction; Safety-colored moving components; Optional pre-galvanized or corrosion-resistant materials |

Why Choose Us
Industrial Kinetics Pallet Conveyor Drawbridges are engineered as fully integrated conveyor components rather than add-on access points. Proven hydraulic lift designs, redundant mechanical locking, and robust structural construction provide long-term reliability in high-traffic industrial environments. Each drawbridge is custom-engineered to match the conveyor system, pallet type, and operational requirements.

System Integration
Pallet Conveyor Drawbridges are designed to integrate seamlessly with chain conveyors, CDLR conveyors, pallet stops, transfers, and control systems. Electrical and hydraulic interlocks ensure safe operation within automated pallet handling systems, including robotic palletizers, stretch wrappers, dock conveyors, and warehouse automation platforms.
What industries typically use these systems:
01
Manufacturing: Crossing pallet conveyor lines between production cells.
02
Warehousing & Distribution: Forklift and pedestrian crossings in pallet handling systems.
03
Food & Beverage (Secondary Areas): Controlled access across pallet conveyor lines.
04
Dock and Truck Loading Systems: Integration with dock door conveyors and trailer interfaces.
05
Automated Systems: Access points within palletizing, depalletizing, and ASRS systems.
Frequently Asked Questions
Does a drawbridge interrupt pallet flow?
When closed, the drawbridge functions as a continuous section of conveyor with no interruption to pallet flow.
How is safety ensured when the bridge is raised?
Hydraulic and manual safety pins, position sensors, and control interlocks prevent operation unless the bridge is fully secured and project / application specific safety conditions are met.
Can drawbridges support forklifts driving across?
The drawbridge creates an opening for forklifts to pass through the conveyor line; it is not intended to support forklift traffic when closed unless specifically engineered for that purpose.
Are CDLR decks available instead of chain decks?
Yes. CDLR deck configurations are available based on pallet type and system requirements.
Can drawbridges be customized?
Yes. Bridge length, width, deck type, chain configuration, locking methods, and controls are commonly customized per application.
