Portable stair climber – Stairs are a basic element of architecture when it comes to joining several floors. They have always been considered according to their function, and seldom serve for anything more than they are. A climbing ladder truck makes it easier for a person to take a heavy load up or down stairs, compared to using a regular car. A climber does this with a unique triple wheel design that rotates and levers its load.
Some carriages have a mechanism in the wheels that locks them in a position where only one of the three wheels touches the ground, which makes the maneuvering of the truck easier. The wheels of a portable stair climber carriage are arranged so that as the user pulls the carriage down the ladders, the gap between the two wheels engages the corner of the ladder.
A lever wheel effectively on the upper ladder and the user applies pressure to pull up the carriage. The wheels then rotate to the next step. From a car portable stair climber levers a load on the stairs, it takes a little pressure from the person using the car. He does not have to completely lift the cart and its contents, which reduces stress on his body and lowering the possibility of injury.
