Method and elevator

A method for controlling movement of an elevator car in an elevator, wherein the elevator comprises the elevator car arranged to travel vertically in a hoistway along at least one guide rail, and a suspension roping for suspending the car during travel thereof in the hoistway, the elevator car comprising an openable door in a doorway leading to an inside space of the elevator car, and a park brake for holding the elevator car immovable at a landing, the park brake being mounted on the elevator car, the method comprising:

• driving the elevator car vertically to a landing;
• activating the park brake mounted on the car;
• holding the car immovable at the landing with the park brake mounted on the elevator car, said holding comprising compressing at least one guide rail by compression members of the park brake with a compression force having a first value;
• opening a door for allowing loading and/or unloading of the elevator car;
• maintaining the door open for allowing loading and/or unloading of the elevator car while the car is held immovable;
• starting closing movement of said door;
• and
• after said starting closing movement of said door:
• relieving the park brake for allowing the elevator car to start to move vertically, said relieving comprising reducing the compression force of the park brake to be smaller than said first value, such that the compression members start sliding vertically against the guide rail;
• maintaining compression with the compression force having a value smaller than said first value, allowing the compression members to continue to slide vertically against the guide rail;
• and
• thereafter removing the compression force.
