KFX GF-Slider Motor
The drive under every GFM slider.
Built for the moves a slider gets asked for: car shots, slow controlled push-ins, pack shots. KFX Technology engineered the motor for the GF-Slider; it drives every GFM slider length, and it runs underslung.

What it pulls
Mounted on a car rig, taking the camera up a steep incline, or running underslung beneath the rail: 60 kg horizontally, and 15 kg at full speed on a 20-degree incline.

You stay in full control
The handheld remote keeps speed, smoothing and feathering on physical controls — intuitive enough to hand to anyone on set. Repeat software is available for simple, frame-accurate saved moves, and a KFX remote head turns the rig into full three-axis motion control, time-lapse included.
