Instead, Rise Robotics uses electric motors for the robot, which wind and unwind belts via deflection pulleys and thus develop the immense force required to lift heavy weights. The system has even ...

while a movable pulley reduces the amount of force needed to lift a weight. By using multiple pulleys in a system known as a block and tackle, the force required to lift a weight can be ...

In an effort to address this, the AVA consortium, a group of UK engineering SMEs funded by Innovate UK and Network rail, has developed a novel modular footbridge and lift system that is claimed to be ...
