Gear Units for Overhead Trolley Systems HW/HK/HS Series

  • Special gearmotors with integrated coupling are required for operating overhead trolley systems. SEW-EURODRIVE offers a range of drives for overhead trolley systems. Drives for overhead trolley systems are divided into two groups:
    • Light load range: Drives for overhead trolley systems according to VDI 3643 guideline (C1 standard)
    • Heavy load range: Drives for heavy duty overhead trolley systems
  • These drives are designed for transport power, transport speed and working load.
  • Your benefits
    • High permitted overhung loads: highest working loads
    • Energy-efficient
    • Reproducible stopping accuracy
    • Fully capable of operating with an inverter
    • Can be combined with many SEW-EURODRIVE modular unit options

Light load range - HW series

Light-load drives are quiet and comply with C1 guideline standards (VDI guideline 3643). They work with a reliable disengageable coupling and provide the following benefits:

  • Low-maintenance for a high level of availability and productivity
  • Smooth running for vibration-free operation
  • Low-noise for use in skilled manual workstations
  • Compact for space-saving installation

Type Maximum torque [Nm] Permitted wheel load [N] Gear ratio Shaft d x l [mm]
HW10 20 2,500 6.75 to 16.5 14 × 28
HW30 70 5,600 8.2 to 75 20 × 35
25 × 35

Heavy load range – HK series

Particularly the heavy load range has seen a clear trend toward increasing permitted working loads. As helical-bevel gear units have higher efficiency than helical-worm gear units, SEW-EURODRIVE has expanded the HK product series. Overhead trolley drives with helical-bevel gear units (HK series) can now be used for wheel loads up to 40,000 N (8,992.4 lbf). Power consumption is reduced significantly, particularly when used in combination with the MOVITRANS® contactless energy transfer system. We ensure that your systems work with even greater profitability.
