Notes: Explanations to Lifting Load 1) The rated lifting load value given in the table is the maximum lifting capacity when the crane is set on solid and level ground. The load should not exceed 75 % of the tip-over load; 2) The total rated lifting load given in the table includes the weight of hook and slings; 3) The working radius given in the table is the actual value including the deformation amount of the boom, so lifting operation should be carried out as per working radius. 4) 75 % of the tip-over load takes into account wind force 6, i.e. lifting operation still can be carried out with fully-extended outriggers when the wind pressure reaches 125N/m2, but lifting operation with tyres or traveling with load are prohibited. Performance specifications of RT30 1. Superstructure 1) FRAME (Swing table) Anti-torsion, anti-fatigue, made of high-tensile steel, all welded construction with demountable counterweight, connection to the truck chassis by single row ball slewing ring designed for 360 degrees continuous ring rotation. 2) SLEWING GEAR Hydraulic axial piston motor driven through planetary speed reducer. Continuous 360° swing. With planetary gear. Four-points contact ball slewing ring. Hydraulic brake (spring-loaded static brake), swing speed: 2rpm. Motor: Axial piston fixed displacement motor 3) SLEWING RING Type: single-row four-points contact ball slewing ring, as the connection of the superstructure and the carrier, 360° swing.
