Motorized Drums (WDD)

Motorized Drums (WDD)

Dinamic Oil’s Motorized Drums (WDD) empower our customers to design their own hoist. The WDD is composed of a planetary winch drive (WD Series) and a cast or fabricated drum and external bearing support. The drum length and flange diameter are customer defined along with the drum style (grooved or smooth) reduction ratio and input motor and brake configuration. The end product can be supplied with the hydraulic motor and valve or without, all according to the customer’s requirements.

With our Motorized Drum Series, your ability to imagine it is the only limiting factor.
