Abstract
The invention relates to a mast arrangement for a construction machine with a mast having a mast guide, along which a mast carriage is supported in a movable manner which is connected to a hydraulic source and has a first hydraulic coupling part for hydraulically connecting a tool unit to a hydraulic source on the mast carriage. According to the invention provision is made for the tool unit to have a tool guiding device. On a frame of the tool unit a second hydraulic coupling part is arranged. Upon movement of mast carriage and tool unit towards each other along the mast guide the first hydraulic coupling part of the mast carriage can be linked up hydraulically to the second hydraulic coupling part on the tool unit. A locking device is provided which is spaced from the hydraulic coupling parts and has at least one hydraulically operable latch bolt.
