The steering and lifting mechanisms are mainly applied to the forestry operations chassis. The steering mechanism can be used as an intermediate hinge structure for connecting a chassis having a towing property. The lifting structure can be used as a self-leveling structure to improve the road surface profile and obstacle stability.

In deep-ocean mining operation, the fatigue life of lifting pipe has always been the focus of field operators, and the fatigue failure mechanism has attracted more and more attention of scholars, but it has not been effectively disclosed. Therefore, in this work, a multi-field coupling and multiple nonlinear vibration model of lifting pipe is established, which can accurately …

Lifting mechanisms were used, less stressful and more effective than manual transportation. The first drainage mechanisms in mining were found in Egypt during the Ptolemaic era. Engineers from Alexandria's School designed some mechanisms made of wood, like a wheel to evacuate water from the inside of the mine. Later, the Romans used the

Efficiency calculation for a specific design of a gravity energy storage system is given as an example. High sensitivity of the system's RTE to the mechanical parameters of the lifting mechanism is demonstrated. The estimated RTE has comprised 86 % for a 900-kW lifting system that transports a weight at a nominal speed of 1.5 m/s.
