TKF’s PosiGrip is Available in a Variety of Configurations to Solve Many Material Handling Applications.

PosiGrip from TKF is a powered, non-contact, zero pressure accumulation conveyor system and is available in a variety of flexible configurations.

  • PosiGrip comes in both standard motor driven and motorized roller driven zero pressure accumulation styles. It is available in standard sizes from 18" to 45" effective widths and zone lengths from 15" to 60". Other sizes are available upon request. Capable of running from 25 to 120 FPM with roller centers of either 2 ½” or 3 ¾”, and unit loads of up to 400 lbs. per zone, PosiGrip will meet the needs of most conveying requirements.
  • PosiGrip driven roller curves are available with a 32 ½” inside radius and 18" to 42" effective widths. They can be equipped with straight, tapered or true tapered rollers. Special radius and widths are available upon request. When used with the company’s PosiGrip accumulation conveyor, the curve allows for uninterrupted accumulation with no external sensors or logic required.
  • The PosiGrip lifting gate section creates a unique and effective solution when access behind or through a conveyor section is required. The units come in standard PosiGrip widths of 3'-0" or 4'-0" openings and can be built to meet specific requirements. It is self-contained and operates on a standard 110V electrical supply. A gas spring assists in the lifting mechanism. The result is a relatively lightweight and very economical and dependable gate section.
  • While TKF’s popular popup transfer lifts do not utilize PosiGrip rollers, they can be incorporated into a PosiGrip conveyor system. They lift items vertically, and then conveys them 90° to an adjoining conveyor. The system utilizes a mechanical linkage to guide lifting. Strands are driven by a motorized roller, eliminating chain drives and resulting in quiet operation. There are no vertical guides or cam ramps used for positioning, and no slides or bearings used in its construction, making the pop-up transfer conveyor simple to maintain. They are compact and utilize state of the art patented low maintenance design components. Available in either V-Belt, O Belt, Timing Belt or multi strand chains configurations, users have a choice of 2, 3 or 4 strands with spreads between 10 3/4" and 33 1/4" standard, with alternatives available upon request.

In all PosiGrip configurations, gear teeth for the roller drives are formed directly into the rollers and are powered by synchronous geared belting in a positive, non-slip drive configuration. The geared design provides superior drive force versus line shaft and O-ring driven conveyors. Each motorized drive roller includes a drive card that allows easy adjustment of speed in each zone providing complete control over product spacing. Since the zones are powered independently of one another and only when required, power consumption is minimized.

There are no separate sprockets or gears and no welded drive components. This results in a low-maintenance, compact and low-profile design. Since there is no metal-to-metal contact, product life is extended, there is no lubrication required, and operation is clean, smooth and quiet.
