Le Elevator Lifting Mechanism Mechanical Structure is the core assembly responsible for the safe and efficient movement of the car within the hoistway. This technical dessin provides an in-depth look at the traction system, often referred to as the “power heart” of the elevator. It features a high-performance electric motor—either geared or gearless—integrated with a precision-machined drive sheave. The design is meticulously engineered to manage the friction-based relationship between the multi-strand steel hoist ropes and the sheave grooves, ensuring a reliable grip that prevents slippage even under maximum rated loads.
By utilizing this professional dessin, engineers can examine the structural bedplate that supports the entire weight of the traction machine, as well as the electromagnetic braking system designed to fail-safe and lock the motor in place during power interruptions. The layout also includes detailed geometry for the overspeed governor and the guiding pulleys, which work in tandem to direct the cables toward the car and counterweight. This CAD model is an indispensable resource for understanding the load distribution and torque requirements necessary for modern vertical transportation, whether for high-speed passenger lifts or heavy-duty freight elevators.
Integrating this pre-engineered mechanical structure into your project reduces the risk of alignment errors between the motor shaft and the hoistway center line. The drawing adheres to industrial safety standards, providing clear specifications for component materials and fastener locations.
