Traction Elevator counterweight overbalanced percentage

[Parachute]

Hello everyone,

If a geared traction machine has a machine data plate that says CWT percentage 40%. is there any other design / safety concerns if the unit is balanced at 45% but the motor amps is within the motor data plate when operating at full load / no load and all the functional tests work correctly?

Welcome to PF.

At first reading, it might seem to be OK, but there will always be safety concerns during operation. It is very hard to be sure when an engineer does not know what the machine does, and cannot inspect the equipment.

Is that CWT 45% a maximum or a minimum?
