Trolly driving apparatus of crane system for mobile harbor

摘要

PURPOSE: A trolley drive system of a crane system for a mobile harbor is provided to facilitate a manufacturing work and to improve stability. CONSTITUTION: A trolley drive system of a crane system for a mobile harbor comprises a frame (301) and a first trolley drive assembly (310). The first trolley drive assembly is movable to the frame along a first direction. The first trolley drive assembly comprises a first transfer part (315), a first cylinder (311), a second cylinder (316), a first cylinder drive wire (312), and a second cylinder drive wire (317). The first transfer part is relatively movable to the frame. The first and second cylinders have cylinder rods moving in a direction parallel to the first direction. The first cylinder drive wire transfers the driving force from the first cylinder to the first transfer part to translate the first transfer part to the frame in the first direction.
