Where are 2:1 systems always re-roped?

In a 2:1 suspension system, the relationship between the hoisting ropes and the elevator car is such that two segments of rope support the weight of the car while a single segment connects back to the machine room. Roping a 2:1 system at the top of the hoistway is essential for proper operation because it allows the system to effectively distribute the lifting forces among the pulleys and the hoisting mechanism.

When re-roping at the top of the hoistway, the technician can ensure that the ropes maintain the proper alignment and tension required for smooth operation. This re-roping practice also allows for adequate inspection of the pulleys and hardware associated with the system. Proper tension and alignment are critical in reducing wear and minimizing the risk of rope failure, which could lead to unsafe operating conditions.

Choosing to re-rope at either the bottom of the hoistway or at the car's floor level may not provide the necessary access to adjustments and proper alignment required for the 2:1 system. Re-roping in the machine room would not typically allow for direct interaction with the suspension for proper adjustments. Thus, re-roping at the top ensures that all necessary factors are accounted for in maintaining the safety and
