The present invention is a device for ascending masts that are designed with a longitudinal groove (mast track). The invention comprises two foot plates (shoes) with specially designed toe mounts and one or two hand grips, all of which are entered and slides in the mast track and by means of which a person climbs up the mast, not unlike the ascending of telegraph pole by means of pole shoes. Sliding and locking of the toe mounts and the hand grips are controlled by the friction between the mast and fittings attached to the mounts. The function of the hand grips is primarily as a fix point for the cord to the safety harness of the climber. |
