Benefits of Edge Roller Technology (ERT) 250 Conveyor
Dorner’s precision edge roller pallet and tray handling conveyors provide efficient, non-contact zoning for medium & heavy load assembly automation applications. They feature a clean, open roller design and are ISO Class 4 approved for cleanrooms.
Best For:
- Pallet & tray handling
- No & low back pressure accumulation
- Cleanroom applications
- Large & medium assembly automation
- Medical Product Manufacturing
- Packaging
- Medical Device Manufacturing
- Automotive Assembly
- Electronic & Consumer Goods Assembly
- Appliance Manufacturing
Sizes & Measurements
- 120 mm to 960 mm wide
- 150 mm long tray minimum
- 38 mm diameter rollers on 50 mm centers
Loads & Speeds
- Loads: up to 114 kg (250 lbs) per pallet or tray
- Up to 6.8 kg (15 lbs) per roller
- Speeds: up to 37 m/min (121 ft/min)
Pallets
- 320 to 800 mm pallets
- Static conductive HPDE skirt
- Proximity sensor pick-up on side and bottom
- Optional pin tracking ball bearings for corner conveyors
Zone & Slip Roller Technology
- Non-contact zone control eliminates pallet stops and costly pneumatic valves
- Low back pressure slip rollers can be used for full length with conventional pneumatic pallet stops
- Individual rollers can be replaced without affecting the remaining portion of the conveyor
Easily Reconfigurable
- Gears, drive shaft, and gearmotor can be repositioned in the field
- Lower gears can be removed and gearmotor added to create new zones
- The drive shaft can be moved to any roller zone and relocated to the lower height for added product clearance
Patent Pending Gearbox Drive Design
- Durable, linear gearbox design provides a robust and flexible method of driven rollers
- Reversible motors for assembly automation
- 50 watt, 3.5 amp, low voltage brushless DC motors save space and provide improved efficiency
- All motor controllers are Ethernet IP, Modbus TCP or PROFINET for easy of control logic, wiring and communication
