Synthesis of Elevator Mechanisms in X with Complex Triad Type Kinematic Chains

Abstract

The mechanisms of the elevators in X usually have a simple structure with hinged, scissor-type bars, having one or more levels. In the last period, models of elevators with articulated bars in X with complex structure with triad type kinematic chains were made. For such an elevator with triadic chains, a construction diagram (dimensioned drawing) is presented, after which the kinematic diagram of the plane mechanism with articulated bars and guided rollers is executed. The structural-topological analysis aims at the mobility calculation and is complemented by a frictionless static calculation.
