The innovative jib system adopts embedded block, plug-in boom head and international advanced U section jib, which has excellent lifting performance and safe and reliable lifting work.
• The unique stretch and retract technique avoids the bend of the core pipe and cylinder and the break of the boom caused by misoperation, improving the safety of the operations.
• Eight patent techniques ensure the smooth, high efficiency and energy conservation of the lifting, rotation, and luffing systems.
• The torque limiter adopts colorful LCD display, realizing the intelligence of the failure diagnosis. The precision is ahead of the industry.
• Adopt the new hydraulic motor with big torque starting point, making the secondary lifting safer.
• The humanity design makes the cab and control cab more spacious, and easy to operate.
• Six unique manufacturing technologies ensure the high quality. • The working condition expands twice. Newly add 5t counterweight. | Unit | QY70K-I | | Overall length | mm | 13930 | | Overall width | mm | 2800 | | Overall height | mm | 3575 | | Weight | | | | Total weight in travel | kg | 43000(without 1t vice counterweight) | | Front axle load | kg | 17000 | | Rear axle load | kg | 26000 | | Power | | | | Engine model | | WD615.338(domestic III) | | Engine rated power | kW/(r/min) | 276/2200 | | Engine rated torque | N.m/(r/min) | 1500/1400 | | Travel | | | | Max. travel speed | km/h | 80 | | Min. turning diameter | m | 24 | | Min. ground clearance | mm | 327 | | Approach angle | ° | 19 | | Departure angle | ° | 13 | | Max. grade ability | % | 40 | | Fuel consumption for 100km | L | 45 | | Main performance | | | | Max. rated total lifting capacity | t | 70 | | Min. rated working radius | m | 3000 | | Turning radius at turntable tail | m | 3.55 | | Max. lifting torque | kN.m | 2303 | | Base boom | m | 11.6 | | Fully extended boom | m | 44.5 | | Fully extended boom+ jib | m | 59.5 | | Longitudinal outrigger span | m | 6.1 | | Lateral outrigger span | m | 7.3 | | Working speed | | | | Boom luffing time | s | 60 | | Boom full extension time | s | ≤150 | | Max. swing speed | r/min | ≥2.0 | | Max. speed of main winch (single rope) (no load) | m/min | ≥130 | | Max. speed of aux. winch (single rope) (no load) | m/min | ≥108 |
