Method and arrangement for moving a heavy load

A method for moving a load, comprising the steps of:

• lifting and/or lowering the load with an elevator, which elevator comprises an elevator car and a hoisting machine, which hoisting machine is arranged to move the elevator car from one level to another in a normal operation of the elevator for moving passengers;
• connecting a hoist to the elevator car for moving the load, the hoist being separate from the hoisting machine;
• removing the elevator from the normal operation;
• moving the load into the elevator car, wherein the load is to be supported by the elevator car, and moving the elevator car by means of the hoist until the load is at a desired height;
• and
• removing the load from the elevator car,
• wherein, before moving the load supported by the elevator car, free play of a hoisting rope connected to the elevator car is removed by lifting the hoisting rope until the hoisting rope is taut, via which hoisting rope the hoist is connected to the elevator car, and
• wherein, before transferring a machinery brake from a braking position to a non-braking position, an upwardly-directed force is exerted on the elevator car by the hoist, which force is a magnitude of an imbalance of the elevator.
