Method for installing the hoisting roping of an elevator

A method for installing a hoisting roping of an elevator, the elevator comprising at least an elevator car that moves in essentially a vertical direction in the elevator hoistway, a counter weight, a hoisting machine, a traction sheave, and a plurality of diverting pulleys including a counterweight diverting pulley, said method comprising the steps of:

• locating a plurality of hoisting ropes around the plurality of diverting pulleys, the plurality of hoisting ropes forming the hoisting roping of the elevator after the installation;
• locating each of the plurality of hoisting ropes around the traction sheave by
• forming a loop with a segment of a corresponding one of the hoisting ropes;
• and
• guiding the loop from a first side of the traction sheave, over the traction sheave, to a second, opposite side of the traction sheave;
• increasing the length of the loop located on the second side of the traction sheave;
• and
• locating the loop around the counterweight diverting pulley after the step of increasing the length of the loop located on the second side of the traction sheave.
