Please contact Thomas for quote.Thomas has designed its Round Bottom with theuser in mind. We have incorporated larger heat-treated sprockets into our designs to reducenoise, vibration and chordal action while increas-ing chain and sprocket life. Our goal is to reducemaintenance and operating costs for the user.We offer the Round Bottom Drag with either a rail return or optional Flight Saver Idlerreturn system. Both systems assure long life and quiet operation. All drag flights are a (food safe) white UHMWpolyethylene material attached to welded steelchain, with exception of the 6" drag conveyorwhich uses combination chain.ROUND BOTTOM CONVEYORCapacity FPM/RPM NOTES: 1. Capacities are based on 100% loading with free-flowing grains at 48 pounds per cubic foot.2. Selection of conveyors should be based upon material characteristics.3. Capacities and speeds will vary for other types of materials and for materials conveyed at an incline.Please consult factory if you have any ques-tions concerning your application.NOTES: 1. Tail and head weights shown include bearings, shafts, and standard sprockets.2. Intermediate weights include return rails and bolted covers.900 9? 2040 33 2600 41 3050 50 3500 58 4080 661200 12? 3475 33 4300 41 5200 50 6075 58 6950 661400 14? 4750 33 5900 40 7100 50 8300 58 9500 661600 16? 6050 32 7600 40 9150 48 10600 56 12100 641800 18? 8100 32 10150 40 12300 48 14300 56 16200 642000 20? 10500 23 13000 29 15650 35 18200 40 21000 462400 24? 14800 23 18150 29 22000 35 25750 40 29600 46100 FPM 125 FPM 150 FPM 175 FPM 200FPMCFH RPM CFH RPM CFH RPM CFH RPM CFHSeries Size900 3/16 367 3/16 89 3/16? 187 14 ga. 185 3/16 255 14 ga.1200 3/16 394 3/16 127 3/16? 210 12 ga. 285 3/16 420 14 ga.1400 3/16 412 3/16 140 3/16? 221 12 ga. 310 3/16 460 14 ga.1600 3/16 475 3/16 160 3/16? 257 12 ga. 365 3/16 520 14 ga.1800 3/16 575 3/16 238 3/16? 281 10 ga. 507 3/16 640 12 ga.2000 1/4 856 3/16 295 3/16? 486 10 ga. 578 3/16 705 12 ga.2400 1/4 899 3/16 370 3/16? 665 10 ga. 742 3/16 870 12 ga.Material Thickness and Approximate Shipping WeightsIntermediateStandard Duty Weight2 Specifiic Duty Weight2CoverSeries Adj.

Conveyors shall not be operated unless all coversand/or guards for the conveyor and drive unit arein place. If the conveyor is to be opened forinspection cleaning, maintenance or observation,the electric power to the motor driving the convey-or must be LOCKED OUT in such a manner thatthe conveyor cannot be restarted by anyone;however remote from the area, until conveyorcover or guards and drive guards have beenproperly replaced.2. If the conveyor must have an open housing as acondition of its use and application, the entire con-veyor is then to be guarded by a railing or fence inaccordance with ANSI standard B20.1-1993, withspecial attention given to section 6.12.3. Feed openings for shovel, front loaders or othermanual or mechanical equipment shall beconstructed in such a way that the conveyoropening is covered by a grating. If the nature ofthe material is such that a grating cannot be used,then the exposed section of the conveyor is to beguarded by a railing or fence and there shall be awarning sign posted.4. Do not attempt any maintenance or repairs of theconveyor until power has been LOCKED OUT.5. Always operate conveyor in accordance withthese instructions and those contained on thecaution labels affixed to the equipment.6. Do not place hands or feet in the conveyor.7. Never walk on conveyor covers, grating orguards.8. Do not use conveyor for any purpose other thanthat for which it was intended.9. Do not poke or prod material into the conveyorwith a bar or stick inserted through the openings.10. Keep area around conveyor drive and controlstation free of debris and obstacles.11. Always regulate the feeding of material into theunit at a uniform and continuous rate.12. Do not attempt to clear a jammed conveyor untilpower has been LOCKED OUT.13. Do not attempt field modification of conveyor orcomponents.14. drag conveyors are not normally manufactured ordesigned to handle materials that are hazardousto personnel. These materials which are haz-ardous include those that are explosive, flamma-ble, toxic or otherwise dangerous to personnel.Conveyors may be designed to handle thesematerials. Conveyors are not manufactured ordesigned to comply with local, state or federalcodes for unfired pressure vessels. If hazardousmaterials are to be conveyed or if the conveyor isto be subjected to internal or external pressure,Thomas should be consulted prior to any modifi-cations.Thomas insists that disconnecting and lockingout the power to the motor driving the unit providesthe only real protection against injury. Secondarysafety devices are available; however, the decisionas to their need and the type required must be madeby the owner-assembler as we have no informationregarding plant wiring, plant environment, the inter-locking of the drag conveyor with other equipment,extent of plant automation, etc. Other devices shouldnot be used as a substitute for locking out the powerprior to removing guards or covers. We caution thatuse of the secondary devices may cause employeesto develop a false sense of security and fail to lockout power before removing covers or guards. Thiscould result in a serious injury should the secondarydevice fail or malfunction.There are many kinds of electrical devices forinterlocking of conveyors and conveyor systemssuch that if one conveyor in a system or process isstopped other equipment feeding it, or following itcan also be automatically stopped.Electrical controls, machinery guards, railings,walkways, arrangement of installation, training ofpersonnel, etc., are necessary ingredients for a safeworking place. It is the responsibility of the con-tractor, installer, owner and user to supplement thematerials and services furnished with these neces-sary items to make the conveyor installation complywith the law and accepted standards.Conveyor inlet and discharge openings aredesigned to connect to other equipment or machineryso that the f low of material into and out of theconveyor is completely enclosed.One or more caution signs (as illustrated below)are attached to conveyor housings, conveyor coversand screw elevator housings. Please order replace-ment caution labels should the labels attached tothis equipment become illegible.The label shown below has been reduced insize. The actual size is printed next to the label.
