Abstract: The present disclosure relates to a crusher mantle lifting device. Attachment elements are configured to be attachable to a crusher mantle. Each attachment element includes a main portion having an inner surface facing the mantle and an outer surface. A locking portion projects from the inner surface and is configured to protrude into a corresponding opening in the mantle. One or more lifting portions project from the outer surface. A tightening means is configured to press the attachment elements towards the crusher mantle. The disclosure also relates to an arrangement and a method.

Abstract: The present disclosure relates to a sealing member for a gyratory crusher having a main shaft and a mantle. The sealing member includes a first side and a second, opposing, side and the first side is arrangeable on a circumference of an inner wall of the mantle of the gyratory crusher and at least a portion of the second side is at a distance from the first side, the distance being not less than the difference between a radius of the inner wall of the mantle where the sealing member is arrangeable and a radius of the outer wall of the main shaft where the sealing is to contact the main shaft for sealing a space between the mantle and the main shaft. The sealing member provides an efficient and safe way of installing a mantle of a gyratory crusher.
