2.Long-time and high-power operation
YUTONG Hydraulic Crawler Dynamic Compaction Machine YTQH450
1. Wideapplication range of strong tamping construction:When there''s noattachments used, the tamping capacity can reach up to 400 t.m tomeet the requirement of most strong tamping construction. Thetamping capacity can reach up to 800 t.m when gantry isused.
2.Excellent performance of power unit: The 179 kW Cummins dieselengine with "GB Ⅱ" emission has strong power as well as reliable,economical and environmental performance; the 140 kW variable mainpump with high transmission efficiency.
3. Highstrength, high reliability and good stability of chassis: Theretractable chassis mechanism hoisted by the 70 t grade creeper hasan extendable folding bracket. When working, the creeper lengthwill be 6, 055 mm, and the width can reach up to 4, 830 mm, mediumdiameter of slewing bearing adopted is 1, 806 mm, and with a highstrength and excellent overall stability; the built-in planet gearreducer and large torque running motor has a large driving force,strong grade ability and high reliability regardless of externalinfluence. The ground clearance of chassis is larger than 360 mm,and grounding pressure is only 0.067 MPa to facilitate a strongpassing capacity.
4. Highstrength of boom:The boom formed by welding of high strengthstructural pipe has a main chord pipe specification of φ76X9, andhas good rigidness, light weight and strong carrying capacity. Theupper section of boom has a projected "Goose head" structure whichis more applicable for strong tamping construction; the ratchet canlock the derricking winch mechanism to further ensure a safe andreliable positioning of boom.
5. Largepulling force of single rope of lifting winch:For the lifting winchwith free hook falling function and M7 working level, the maximumpulling force of single rope can reach up to 10–13 t, and maximumrope speed can reach up to 110m/min. The built-in normally closedbrake can ensure a reliable braking of tamper.
6.Convenient and agile operation:The hydraulic control system adoptsarmrest box type pilot handle control and load sensor withmicro-motion function which is convenient and agile; the swingmechanism has controllable free slipping mechanism to facilitate astable operation without impact.
7.Working with long time and large power:The hydraulic system isequipped with an independent cooling system to ensure the engineand hydraulic system can work for a long time with large power notresulting in over-temperature. The useful volume for the enlargedfuel tank can up to 500 L to efficiently guarantee a day''sworking.
8. Highsafety:It is provided with electronic combination instrument,integrated control device of engine data, and automatic warningdevice; it is also equipped with safety devices such as rotarytable swing locking device, boom anti-overturn device, winchover-rolling protection device, lifting ultimate micro-motiondevice etc to make sure safe and reliable working.
9.Comfortable operation:The shock absorbing connected cab has a widerange of view and beautiful appearance, and is equipped with aguard screen. The human-oriented design inside the cab such asshock absorbing seat, fan, heater and optional MP3 audio player canprovide a comfortable operation and good workingenvironment.
10.Convenient transportation:The external dimension for the mainmachine is 7, 240 X 3, 300 X 3, 400 mm. When transporting, only theboom and balancing weight is necessary to be removed instead ofdisassembly of the whole machine, and the maximum weight for asingle piece is 36.5 t to facilitate a low transportation cost. Thesupported type balancing weight with the maximum single pieceweight of 6.2 t is more convenient for the installation, disassembeand transfer.
