Safe Ladder / Ladder

problem :
What is the most dangerous about working on a regular ladder is when you have to carry installations such as tools, signs, ventilators up. You have to hold the ladder with one hand but have a risk of falling off and getting injured if you lose balance. It is the same when you have to carry objects or tools down from the top.

Solution:
A pulley is installed on the ladder. You can turn its handle to lift objects up and down on a board. You don’t have to climb up or down the ladder while carrying the objects and can easily exchange them with your co-worker. The ladder is designed conveniently and safely for its users.
