This gadget helps ski elevate operators connect chairs to the cable

Most ski lifts are fairly easy methods: they use large ol’ motors to drag cables with chairs or hangers connected. Extra superior removable designs let the chairs come off the cable quickly whereas within the terminal, so skiers can hop on at a leisurely tempo. However fundamental fixed-grip chairlifts don’t have that functionality and skiers have to leap on whereas the chairs transfer at full pace. To assist ski elevate operators house these chairs correctly, Marc Antaya designed the Ski Raise Spacer 2000.

Antaya was working as a liftie at an area ski space and observed that it was troublesome to connect chairs to the ski elevate cable at constant intervals that facilitate clean operation. So he constructed the Ski Raise Spacer 2000, which measures the cable pace and distance traveled, calculates the spacing, and stops the elevate on the proper instances to hold the chairs. It’s wired in sequence with the elevate’s present controls, so it may’t override their security measures. It merely supplies a distant begin/cease perform, which it may carry out when desired for attaching chairs.

The gadget consists of an Arduino Nano Each board, lithium batteries, relays, an LCD display, and a management interface. That interface is necessary, as a result of it lets lifties calculate the chair positions in a number of other ways based mostly on the info they’ve out there. For instance, they will begin with a sure variety of chairs and the cable size. In that case, the gadget will calculate the spacing between chairs. Or they will enter the cable size and desired spacing, wherein case the gadget will calculate the whole variety of chairs required.

To do its job, the gadget must know precisely how a lot the cable strikes. To attain that, Antaya constructed a wheel turned by the cable. It has magnets, which the Arduino can use for rotational encoding because of Corridor impact sensors. That is all configurable within the gadget menu system, the place the liftie can set the wheel circumference/diameter and variety of magnets.

Antaya has already examined an earlier model of the Ski Raise House 2000 at his native ski space. After updating it as proven within the video, it’s prepared for a second spherical of testing.
