SE Horizontal Slew Drive Worm Gearbox With Gear Motor For Solar
Tracking System
Slew Drive Worm Gearbox Description
SE slewing drive utilizes hourglass worm drive technology and
adopts a multi-gear contact hourglass worm structure with good
impact resistance and is suitable for more precise applications to
achieve maximum gear torque and the most stable rotation. A
standard swing drive is equipped with an enclosed housing and a
single self-locking hourglass worm. When the power input is
returned to neutral, the worm will lock the load in place without
any external braking. This design makes the SE slewing drive an
ideal solution for matching the relative rotation of two objects.

Transport, Handling & Storage
Transport only in horizontal position, impacts should be avoided.
Wear work gloves and be careful when handling the slew drive.
Use the holes of the rings in the slew drives to fix bolts for safe
hoisting, handling and placement.
Store only in a horizontal position and in closed rooms, keep it
away from getting wet, the surface corrosion protection of exposed
mating surfaces lasts approximately 1 month in closed packaging.
Longer period storage requires special protective measures.
Transporting unpacked slew rings
Use suitable lifting gear/ never transport product vertically
Unpacked slew drives can be transported with lifting gear under the
following conditions:
- The lifting gear must be configured appropriately for the unit
transport load.
- The ring bolts must be configured appropriately for the weight of
the transport unit.
- The slew drive shall only be transported by itself.
- Transport within the company shall only be executed horizontally.
