Crawler Crane (QUY70)

Basic Info.Model NO.QUY70SpecificationCEOriginJiangsuProduct Description Crawler CraneHigh cost-performance and outstanding lifting capacity: Leading the trade and exceeding your imagination!1. The control system applied to this type of crane is an electronic management system, which adopts CAN bus technology, has intelligent fault diagnosis function and is equipped with intelligent color display.2. The pendant plate made of high-strength plate, which has taken the place of traditional wire rope, has the advantages of excellent rigidity, light weight, great load-bearing capacity and low wind drag etc.3. The crane is equipped with a self-assembly/dismantling system. No auxiliary crane is required for loading, unloading, assembly and dismantling.4. The actuating time of brakes and the opening time of valves fitted in winch mechanisms can be adjusted freely to optimum matching state. The applied advanced PLC controller can make every speed parameter be adjusted within specified range in accordance with the user's habit, which embodies the ergonomic design of our crane.5. The closed slewing mechanism has controllable free swing function which can reduce the impacts on the crane and ensure that superstructure starts/stops slewing more stably. The internal slewing ring and slewing reducer with great load-bearing capacity and high precision can ensure stable and precise slewing motion.6. The traveling mechanism can make the crane have high maneuverability and perform such motions as traveling in straight line, one-side crawler steering, differential steering and turning on the spot as well as traveling with load.7. The main pump control system, which has the functions of advanced load feedback and electrically-controlled power adjustment, makes the crane have good jogging performance so as to satisfy the demands in different working conditions required by customersItem Value Remarks Max. lifting capacity × Radius       t × m 70×3.8  Deadweight with basic boom           t 61  Main boom length                   m 12~57  Fixed jib length                     m  6~18  Max. lifting capacity of fixed jib        t 6.4  Offset angle of fixed jib               ° 10,30  Max. length of main boom with fixed jib m 42 + 18  Max. speed of single rope on drum Main winch          m/min 120 The 4 th rope layer Auxiliary winch      m/min 120 The 4 th rope layer Derricking winch     m/min 45 The 4 th rope layer Slewing speed                     rpm 0~2.4  Traveling speed                    km/h 0~1.35  Gradeability                         % 30  Ground pressure                   MPa 0.074  Overall dimensions (L×W×H)          m 11.2×3.3×3.2 Incl. mast, boom bottom section Engine Rated power/ rotational speedkW/rpm 153/2200  Max. output torque/ rotational speed                Nm/rpm 929/1300  Emission standard                   TIER 3  Crawler gauge × ground contact length × track shoe width                    mm 2540×5040×1000 Crawler carrier retracted 4000×5040×1000 Crawler carrier extended       Lifting Capacity Table of Main Boom                                                             Unit: tBoom length (m)      Radius (m) 12 15 18 21 24 27 30 33 36 39 Radius (m) 3.8 70          3.8 4 65 65 58.2/4.1 51.2/4.6       4 5 53.6 52.3 51 49.8 44.2/5.2 37/5.7     5 6 40.5 40.1 39.3 38.5 37.7 36.9 34/6.2 30.4/6.7   6 7 32.1 32 31.8 31.2 30.6 30.1 29.5 28.9 27.1/7.3 24.3/7.8 7 8 26.6 26.5 26.4 26.2 25.8 25.3 24.8 24.3 23.9 23.4 8 9 22.6 22.5 22.4 22.3 22.2 21.8 21.4 21 20.6 20.2 9 10 19.7 19.5 19.4 19.3 19.2 19.1 18.7 18.4 18 17.7 10 12  15.4 15.3 15.1 15 14.9 14.8 14.6 14.3 14 12 14  12.6 12.5 12.4 12.2 12.1 12 11.9 11.7 11.5 14 16   10.5 10.4 10.2 10.1 10 9.9 9.8 9.6 16 19    8.3 8.1 8 7.9 7.8 7.6 7.5 19 20     7.6 7.5 7.3 7.2 7.1 7 20 22     6.7 6.5 6.4 6.3 6.2 6 22 24      5.8 5.7 5.5 5.4 5.3 24 26       5 4.9 4.8 4.6 26 28        4.4 4.2 4.1 28 29        4.1 4 3.9 29 30         3.8 3.6 30 32         3.4 3.2 32 34          2.9 34
