After cracking the hardened sulfur, the miners put them into bamboo baskets. 70-80 kilo is the average for one go. Some miners might carry up to 120 kilo. Cracked collarbones aren't unusual. When the sun rises they start carrying it up to the craters rim where they parked a trolley. With the trolley they roll up to 3 loads of sulfur down to the checkpoint. The checkpoint is 3 km away.
