Working Machine Cylinder Arrangement for Compact Transport

The patent applies dimensionality change by transitioning the cylinder arrangement from a vertical stacking configuration (same width position, different heights) to a horizontal distribution configuration (different width positions, same or overlapping height ranges). Specifically, the internal boom cylinder is disposed at a first position in the width direction, while the arm cylinder is disposed at a second position in the width direction, allowing both cylinders to occupy the same height range without interfering with each other. This spatial reconfiguration in the width dimension resolves the contradiction by eliminating the need for vertical separation while maintaining structural simplicity.

The patent resolves this contradiction by utilizing the width dimension to accommodate both cylinders simultaneously. By disposing the internal boom cylinder at a first width position and the arm cylinder at a second width position, both cylinders can be properly positioned and operated without requiring increased vertical space. This allows the working attachment to maintain a compact height suitable for truck transport while ensuring adequate space for both cylinders at their respective width positions during operation.

The patent addresses the safety concern by redistributing the cylinders in the width direction rather than stacking them vertically. This configuration allows the working attachment to be folded into a compact triple-folded state with reduced height, enabling operators to perform disassembling operations at a lower, safer position on the ground. The internal boom cylinder and arm cylinder are positioned at different width locations, allowing both to function properly while maintaining a low overall height that enhances operator safety and accessibility during maintenance operations.
