Is the Blokart based on 14" Tyres? If so that limits ground clearance if you stick to using them regardless of power or drive options on uneven or soft ground. So a more heavy duty solution that lifts the rear axle up might be needed?

If you can be happy with the height over ground then a simple option will be to drive the front wheel with a hacked Electric Scooter (so tyre on tyre). I have been casually keeping an eye out for a local used one as a parts donor as a walk of shame avoider for longer beach runs. Tuck it in behind the seat in a bag for a just in case and a simple clip/clamp for the front forks and a lever back to the driver for contact pressure and speed control. Driving a single rear wheel will almost certainly fail on sand.

Even buying bits new of AliX or Evilbay isn't that prohibitive. For a Club owned option this sort of thing might be ok for $$ vi.aliexpress.com/item/1005008140963283.html? then an over centre lifting frame for the axle?

Me and a mate were doing a run up the Coorong many years ago and the plan was to get to 28 Mile Crossing from Blackfords and call that done and get picked up. Going great fully powered on 5.5m kites then a tiny shower of rain and then the wind STOPPED at around 20 Miles up. Waited for 30 minutes and still nothing so we decided to trek out over the Dunes to the Road through the scrub.

Dragging and or carrying a 1.4m axled buggy, three kites and basic supplies for what was nearly 2km really was not cool and the Beers were well deserved later on.

More walk of exploration than one of shame. Ran across a Sunshine harvester long forgotten in the Dunes and other assorted farm junk being careful not to step on moving sticks.

Beach Tractor for Buggies but worth a look for your LY job.

You should find those heavy bar treads on small self propelled Tillers or farm gear. I checked Interlink but they have cut down their tire range but shouldn't be to hard to find.

Same Crew but another build without the bar wheels.

Just park a vehicle with a winch at the top of the ramp and drag the karts up. Failing that fit one to the Club trailer (maybe modified to gear it up a bit) and do the same

Unfortunately it's a fair hike from the top of the ramp to the carpark, so that's not an option. Someone did bring along a ride-on mower one day, with a winch fitted and cutter deck removed. that worked, sort of. but involved a fair bit of faffing around. Hoping to find a better solution; we do have some ideas but it'd be good to adopt other people's proven solutions.
