Selection by load

Slew drive selector

Describe your application in plain terms, or enter its loads if you know them. Every drive in the catalogue is checked against its ratings and the ones that carry them are ranked, tightest fit first.

Simple Advanced

Application Service factor: 1.25

Tell us about the load and where it will work; we'll work out the forces.

Start from a typical case

How is the drive mounted? Lying flat: it turns like a turntable Standing upright: it tilts the load up and down

How much does the load weigh? kg How far is the load's centre from the centre of the drive? m 0 if it sits centred. How high is the load's centre above the drive? m It will be outdoors, exposed to wind How long should one full turn take? s Leave it empty if speed doesn't matter. It must hold its position when stopped or with the power off

For engineers: enter the loads on the drive directly.

Loads on the drive

Forces in kN, moments and torques in kN·m (1 tonne ≈ 9.81 kN). Leave a load empty if it does not apply.

Axial force kN Radial force kN Tilting moment kN·m Operating torque kN·m Peak torque optional kN·m Holding torque optional kN·m

How the check works

Each load is multiplied by your application's service factor and compared with the drive's catalogue rating; 100% means exactly at the limit. Axial force and tilting moment are added linearly, a conservative stand-in for the load-limit curve. Fatigue life (dynamic ratings) is not evaluated.

Drives that carry these loads

Preliminary selection. Service factors are provisional, and our engineers confirm every application before quoting.
