Indoff, Inc provides solutions to some very special applications. The latest such solution involves handling drums of nuclear waste. The drums of waste in this application needed to be lifted & manually conveyed into a processing trailer. Drums enter on front end of trailer, where the nuclear material is processed, and then exits at the end of the trailer. Indoff, Inc engineered the following solution:

 1.   (2) Stainless Steel Hydraulic Scissor Lift Tables, totally rated for outdoor use. Both operated by (1) common Hydraulic Power Unit.

2.   (2) Stainless Steel heavy-duty gravity conveyor sections mounted to the top of the scissor-lift tables. Conveyor includes: Double-sealed roller bearings, roller tube, hex axles, and frame, all fabricated from 330 stainless-steel.

3.   Stainless steel pneumatic operated roller brakes, blade stop, and side guides.

Indoff, Inc also has precision crowned rollers primarily used as return rollers in belt conveyors. These rollers are precision ground to desired degree of taper from centerline of roller to bearing seat. (Both sides) Crowned rollers are normally used in belt conveyors with speeds exceeding 100 FPM. The main purpose of the crowned conveyor roller is to aid in belt tracking for higher speed belt conveyors.

• Sulfamate Nickel: an affordable electroless nickel coating, machinable for effective component repair
• Nye-Kote™: robust corrosion protection with thickness accuracy, friction protection and hardness performance
• Kanigen®: A well known corrosion protectant that bonds especially well to interior dimensions and intricate, hard-to-plate parts
• Electralloy™: a thin dense chrome finish that fights corrosion and wear better than traditional plating
• HVOF: Coatings applied with a technologically advanced spray system that maximizes density of deposits, bond strength, deposit thickness and surface smoothness

Wide Variety of Rollers and Components 

In order to properly convey the product smoothly and efficiently, it should be supported by a minimum of three rollers. To calculate the center to center roller spacing required, divide the length of your package by 3. The dividend is your required spacing. For example, a package 12" long when divided by 3 yields a dividend of 4. Therefore, the required spacing would be 4" center to center. Flexible bottom surfaces require four or more supporting rollers per package, calculating spacing would require the same procedure.

 

Driven Rollers with Slip Drive

Series 3800 driven rollers were designed to provide a very economical wayof building chain powered conveyor systems with accumulation capability. Products can be stopped and released at any point on the conveyor without stopping the chain drive. The slip drive relies on friction between two coaxial members. The inner sleeve rotates continuously as it is chain driven. The outer shell, the conveyor roller, is in sliding contact with the inner member through a bushing. The torque applied between the inner and outer member is proportional to both load and speed.Rollers are available in 1.900” and 2.500” diameters. Aluminum, stainless steel,and galvanized steel tubes are available in the 1.900" diameter driven rollers, only galvanized steel is offered in the 2.500" diameter rollers. Both are assembled with commercial grade ball bearings.

Several sizes of our rollers are available with ABEC-1 precision roller bearings.

ABEC-1 precision bearings are available for carbon steel tube in 1.900” x 16 Ga, 1.900" x 12 Ga, 2.500” or 2.625” inch diameter. Precision bearings offer a superior load rating, and higher speeds, while operating at a much lower decibel rating (Quiet Rollers). Rollers are suited for both gravity and powered applications. These precision bearings are grease packed & sealed.

• Tube Diameter: 28, 40, 50, 60, 63.5, 70, 89mm
• Spindle Diameter: 8, 10, 12, 15, H 11mm
• Spindle Ends: smooth, with springs, with flats, with holes
  with male thread, with female thread.
• Made of zinc plated steel upon request.

Rollers: 3.500" diameter x .300 wall heavy-duty tubing, with 1.000" hex cold rolled steel axles, cotter pin retained. Standard Heavy-duty bearings are grease packed. Double Shielded. 2000 lbs. roller capacity.
