Pneumatic Lift Station
Hytrol Special

When assembly operations move large, heavy items, workers often need special material handling accessories to help them in the assembly process. In many cases, the large items are conveyed with low elevation conveyors. When assemblers need easy access to the products, some sort of lift must be employed to provide good ergonomics in the workplace.

This pneumatic lift station was designed to lift 2000 lb. multi-deck merchandiser refrigerators so assemblers can work on them without bending. The conveyor is 13 ft. long and the lift station has a net lift of 10 in. The station raises from 8 in. (top of roller) to 18 in. (top of roller). Air bags provide the lifting action. The lift is stabilized by 12-1/2 in. long guide bolts and two heavy-duty linkage kits.

Conveyor of the Month
Model ACC

The spring of 1967 found Hytrol’s Research & Development area in pursuit of an accumulating conveyor to meet the demands set by distributors and customers. The request called for a conveyor of efficient yet basically simple design to minimize maintenance and cost. Requirements also stated it must be reversible and capable of being adjusted quickly and easily in the event of extreme changes in unit load.

After extensive experiments and trial runs, Hytrol perfected the Model 138-ACC and soon after, the Model 190-ACC. Both conveyors more than met consumer’s needs.

Today, with only slight modifications to the original design, these two models continue to be "best sellers" in the Hytrol line.

The 138-ACC is available in 4 bed widths, from 12 in. to 24 in. The 190-ACC can be supplied from 16 in. to 42 in. wide. A number of sizes are available for 24-Hour shipment from Hytrol’s Stockyards.

Conveyor sections are easily coupled together at either end to make up to 100 ft. long units. The drive is usually located near the center of the conveyor.


Hytrol Special -  Powered Wheel Conveyor

   

Ref. No's: 652744-652748

Designed specifically for air compressor tanks, but could also move a variety of tube-shaped objects, this "special" uses powered 6 in. dia wheels to convey the product. The tanks are moved to a certain location, stopped, and the lift is used to raise them for inspection. The tanks can be rotated while on the lift.

Speed of the unit is 30 FPM. Product weight in this particular case is 200 lbs. One interesting note is the OAW (overall width) of the powered wheel conveyor is adjustable to handle tanks with varying diameters.


Application Information
PULL. . .Don’t PUSH!

Many serious belt tracking and general conveying problems have resulted from trying to PUSH the belt rather than PULL it.

If a conveyor is supplied with an end drive, it is recommended that it be used in a one-direction application rather than in a reversing situation. Look what happens with an end drive in a reversing situation. . .

Recommended direction of travel with an END DRIVE:

Drive pulley PULLS the belt.

When a reversing application is required a CENTER DRIVE is recommended. The drive pulley is located in the center of the conveyor and pulls the belt equally at both ends. The belt will not buckle in this application.
