Summary
At CamelConvey, we craft high-quality power & free conveyor components designed for durability in demanding industrial environments, reflecting our brand’s resilience.

In industrial material handling, power & free conveyor systems offer unmatched flexibility and productivity by decoupling the power source from load carriers, enabling independent load control without halting the entire line. At CamelConvey, we craft high-quality power & free conveyor components designed for durability in demanding industrial environments, reflecting our brand's resilience.
To leverage these systems fully, it's critical to understand their core components—below, we break down their key functions and CamelConvey's engineering advantages.
Power Drive Unit: The Heart of the System
The Power Drive Unit is the engine that powers your power & free conveyor system—responsible for driving the continuous movement of the conveyor chain. Unlike generic drive units, CamelConvey's PDUs are engineered as compact, high-efficiency combinations of inverter-duty motors and reducers, ensuring maximum power transfer directly to the conveyor chain while minimizing noise and maintenance needs. Equipped with an electrical automatic cutoff device, our PDUs automatically stop the motor/reducer in case of overload, protecting both the equipment and your production line from damage.
Whether your application requires light-duty or heavy-duty performance (handling loads from 25 lbs to 3,000 lbs and beyond), CamelConvey's PDUs are tailored to deliver consistent, reliable power—making them the ideal choice for industries ranging from automotive to surface treatment.
Conveyor Chain: The Driving Force
The Conveyor Chain is the critical link that connects the Power Drive Unit to the rest of the system, transmitting power and enabling the movement of free trolleys. CamelConvey's conveyor chains are precision-engineered for durability, wear resistance, and long service life—featuring heat-treated side links, through-hardened alloy steel wheels, and symmetrical drop-forged pins (not stamped) to ensure superior strength and corrosion resistance. Our chains are designed to withstand harsh industrial conditions, including high temperatures (up to 250°C) and chemical exposure, making them suitable for surface treatment lines, curing ovens, and other demanding environments.
A key feature of our conveyor chain design is the integration of pivoting pusher dogs—small mechanical devices spaced at regular intervals that selectively engage with free trolleys. This engagement mechanism allows trolleys to move with the chain when needed, and disengage smoothly when stops are required—without interrupting the chain's continuous movement.
Conveyor Track System: The Guiding Path
The Conveyor Track System serves as the framework for your power & free conveyor, providing a stable, precise path for both the conveyor chain (power track) and free trolleys (free track). CamelConvey's track systems feature a modular, bolted design—eliminating the need for welding and allowing for easy assembly, customization, and expansion according to your floor space and production needs. Our tracks are precision roll-formed from patented microalloy steel, a high-strength carbon steel that is harder, stronger, and longer-lasting than standard materials—an exclusive feature that ensures minimal wear and maximum reliability.
We offer both horizontal and vertical track configurations, with heat-treated wear surfaces on curves to enhance anti-wear qualities. Whether you need 24'' radius horizontal turns or vertical curves for multi-level routing, our Conveyor Track System supports seamless lateral and vertical transfers—making it easy to route loads to multiple destinations without expensive modifications.
Free Trolleys: The Flexible Load Carriers
Free Trolleys are the load-carrying components of power & free conveyor systems, designed to move independently along the Conveyor Track System. Unlike fixed carriers on continuous conveyors, CamelConvey's Free Trolleys can disengage from the Conveyor Chain (via pusher dogs and stop stations) to stop individually or in groups—allowing for operations like inspection, assembly, or storage without shutting down the entire line. This flexibility is a game-changer for high-mix manufacturing, where different loads may require different processing times.
Our Free Trolleys are engineered for stability and versatility, capable of handling a wide range of load sizes and weights. They work seamlessly with our Conveyor Track System and Conveyor Chain, ensuring smooth engagement and disengagement—even in harsh environments. Whether you're transporting automotive parts, coated components, or heavy industrial goods, CamelConvey's Free Trolleys deliver consistent performance and protection against load damage.
