Method for start-up of mobile telescopic crane, involves forming extension arm portions by partial extension portions arranged at distance to each other with bending-resistant connectors, and latching partial arm portions of lower arm

摘要

The method involves forming extension arm portions (11-13) by partial extension arm portions arranged at a distance to each other with bending-resistant connectors (28-31). The extension arm portions are mechanically locked in a longitudinal direction (L) to each other. The arm portions (12, 13) are telescoped relative to the arm portion (11). The arm portions are latched such that the partial arm portions of upper partial extension arms (17, 18) are latched. The partial arm portions of a lower partial extension arm (16) are latched. The partial extension arm portions are designed as hollow cylinders. An independent claim is also included for a mobile telescopic crane.
