Flexible Skate Wheel Conveyors


Shown Expanded	Shown Retracted

An accordion-style frame lets you quickly curve, expand, and retract these conveyors. They have skate wheels for flat-bottom objects in assembly lines or packaging and shipping applications. A package stop on one end keeps boxes from sliding off.

Note: Weight capacities are based on an evenly distributed load.

Steel Wheel—Steel wheels are impact resistant.

Nylon Wheel—Nylon wheels resist moisture and are lighter than steel.

Flexible Roller Conveyors

Expand, curve, and retract the accordion-style frame to position these conveyors wherever you need them. Snake them around obstacles in cramped areas, bend them into a horseshoe to connect two trailers, or stretch them out to extend an existing line. When they’re not in use, retract these conveyors down to a fraction of their length. Their rollers are designed to smoothly transfer flat objects or ones with uneven bottoms. Shipping tubes, drums, and pails are less likely to get stuck in between rollers than between skate wheels.

Note: Weight capacities are based on an evenly distributed load. The length of the material you're conveying should be at least three times the roller spacing.

Modular Mini Chain Belt Conveyors

Build a mini conveyor in any shape you need. These conveyors have curved, straight, incline, and decline runs that you can quickly join together with the included brackets. They're often used in areas with limited floor space and applications that require frequent layout changes. To customize your conveyor, add on components, such as package stops and merge guides, with the built-in T-slots on the side. These conveyors come with guides installed.

You'll need a drive assembly, an idler assembly, and a belt to complete your conveyor. To determine the belt length you need, multiply your conveyor’s length by 2.1. If you need a belt longer than what’s available, you can connect multiple together. Use a belt installation tool to pull out the pin, then line up two ends and push the pin in with the tool to connect them. You can also shorten a belt using the same tool.

Maximum run length is 70 ft. with two 90° curves. Adding more curved conveyors will reduce the run length.

Drive Assemblies


Left Side Motor	Right Side Motor

Install drive assemblies at the start of your conveyor. They include a gearmotor that powers the belt. Use the controller to start, stop, and change the conveyor’s speed. A stand is included.

Choose an assembly with the motor and controller mounted on the left side or the right side, depending on your space constraints.

Incline Conveyors

Incline conveyors let you change elevation. For example, you could build a bridge over your existing conveyor line. To bring your conveyor back to its original height, use a decline conveyor with the same climbing angle.

10° Climbing Angle—Conveyors with a 10° climbing angle require rough-surface belting so items won’t slip off.

15° Climbing Angle—Conveyors with a 15° climbing angle require rough-surface belting so items won’t slip off.

Belting


Smooth Belt Surface	Rough Belt Surface

Attach belting to your conveyor to transport material. It’s driven by the conveyor’s motor. Tabs on the bottom keep it from lifting off the conveyor in curved sections.

To determine the belt length you need, multiply your conveyor’s length by 2.1. Belting is not included with any other components.

Rough Belt Surface—Rough-surface belting has pads on its chain links to grip material. If you’re conveying material at an incline or decline of 10° or higher, this belting will keep it from slipping.

Guide mounts give you more control over the position of guide rails than the ones installed on each conveyor section. In addition to adjusting your guide rail in and out, these mounts also let you adjust the height of the guide rail.

Style A—Style A mounts have two T-slot frame connections, so they’re more stable than Style B mounts for more impact resistance and less movement when the conveyor vibrates.

Style B—Style B mounts have one T-slot frame connection. They have less impact resistance than Style A mounts.

Ready-to-Run Flexible Roller Conveyors

Expand, retract, and curve these conveyors wherever you need them—they’re ready to run once you plug them in. These conveyors are ideal in situations where you need flexibility, such as loading and unloading trucks, connecting two trailers, or extending an existing line that you've outgrown. They have rollers to convey objects of different shapes and sizes in assembly, packaging, and shipping applications. To save space, these conveyors compress down to 8 _1/2 ft. when they are not in use. They’re sometimes kept in storage as a backup line, so you can pull them out if other conveyors unexpectedly shut down.

Grab the handles at each end to move these conveyors into place. The legs adjust to your desired height. Connecting hooks on each end can fasten them to other conveyors. Lock the casters to keep them in place. A knob on the controller face lets you adjust the speed. To prevent damage, sensors at the end of the conveyor will stop the rollers if a package is nearing the edge.

Note: Weight capacities are based on an evenly distributed load. The length of the material you’re conveying should be at least three times the roller spacing.

Telescoping Mobile Skate Wheel Conveyors

Partially Expanded

Fully Retracted

Extend these conveyors more than 60 ft. to move items over long stretches and then retract them to a more compact 10 ft. for storage. Often used to load trailers, they’re best for light duty loading of boxes and other flat-bottomed objects. The first section of these conveyors features a roller conveyor extension. The rollers on the extension have a higher capacity than skate wheels to resist more impact as boxes are loaded onto the conveyor. A package stop on one end keeps boxes from sliding off. To facilitate positioning, these conveyors have handles and multidirectional wheels with rollers that rotate around the wheel core to allow movement in any direction. A floor lock keeps the conveyors in place.
