April, 2015 at the NAB Show in Las Vegas Konova showcased a new K-Cine Video Camera Slider designed to take the heavy payload of high end professional camera systems. This new K-Cine Video Slider has officially opened up for sale today.
Imagine taking two heavy duty sliders and turning them on their sides. Now double up the carriers on each rail (total 4), so that you're moving on a total of 12 steel roller bearings. That should give you a basic idea on it's design, but here's an NAB Show interview with more details (video below).
Konova K-Cine Heavy Duty Cinema Slider
The K-Cine Video Camera Slider is offered up in two lengths from 47" (120cm) to 60" (150cm). Variable drag can be set to allow friction during your slide, and two independent brakes can lock the car from movement.
The Max Payload the K-Cine can support is up to 154lbs, and each Kit will also include a rolling hard case for travel. The K-Cine Camera Video Sliders are available now via eBay (click here).
