BRIDGE CRANE LOAD TROLLEY Russian patent published in 2008 - IPC B66C11/00 

FIELD: material handling equipment.

SUBSTANCE: proposed load trolley of bridge crane has two longitudinal beams interconnected by cross beam and resting on running wheels with fitted-on load lifting drive and trolley travel motion drive members mechanically coupled, respectively, with load drum and running wheels, mounted in pairs on shafts. Load trolley has load gripping member connected with trolley by means of wire ropes and tackle block. Load trolley blocks are made in form of roller arranged on one of shafts connecting running wheels. Cross beam which connects two longitudinal beams is installed parallel to shafts connecting running wheels in the middle and higher at a distance providing stable position of longitudinal beams, thus relieving said shafts from bending stresses.

EFFECT: simplified design, reduced metal usage, cut down required building.
