This technical drawing presents a side elevation view of a 250-tonne capacity crawler crane with a lattice boom configuration. The main boom assembly consists of bottom and top sections with a total extended length of approximately 30.8 meters at a 70° operational angle. Key dimensions include a 19.1m primary boom section, overall, and 12.609m secondary section. The drawing details critical components such as the track undercarriage layout, counterweight positioning, and operator cabin. The boom features multiple radius measurements (R6, R13, R18) indicating swing clear and obviousances. The crane’s tracked base provides stability for heavy lifting operations while maintaining mobility across construction sites. The lattice structure optimizes strength-to-weight ratio, essential for handling the specified 250-tonne lifting capacity while minimizing structural weight.
