Hydraulic shovel support frame - centre fitted to side members of plate bent to inverted V and closed

摘要

The support frame for a hydraulic shovel has a central part (14) fixed to two side longitudinals (15). Each longitudinal is a sheet bent into a reversed V shape and has a closing plate at the lower ends of the V. The fixing is by welding (30). The closing plate has a central part of certain thickness flanked on each side by a strip of thickness greater than that of the central part. The edges of the V are in contact with the upper faces of the side strips. The lower strip edges form a roller contact face.
