Abstract
An elevator installation and a method of operating the elevator system for temporary transportation of an overload within the elevator installation includes a car and a counterweight interconnected by one or more suspension ropes engaging a traction sheave that is driven by a motor. The traction between the suspension ropes and the traction sheave is enhanced independently of the counterweight for intended overload operation.
