ZOOMLION Small 25Ton Mobile Crane ZTC250E552 In Stock For Sale   product descriptionThis type of truck crane, one of the classic products in the same trade, has earned a good reputation from the customers. The truck crane adopts self-made special-purpose chassis with 6×4 drive. The ergonomic streamline semi-mounted driver's cab with double wing door, which has obtained a national patent, makes it convenient for rear rider to get on/off cab.The crane adopts WEICHAI Steyr engine which is specially developed for those cranes that often travel at low speed. This kind of engine not only can produce large output torque when it starts and increase the traveling speed quickly, but also has excellent starting performance and good gradeability.The crane is equipped with 8-speed gearbox which changes gear smoothly and is of simple structure and makes maintenance convenient.The crane is fitted with a 33.3m long hexagon-section boom which is made of high-strength steel, so the boom has strong resistance to bending and torsion. The distinctively-designed circular arc sliding block (having obtained a national patent) makes the stress distributed more evenly, the load carrying capacity stronger, and the adjustment easier. The local rigidity in boom supporting point is good, which has improved the lifting capacity on boom with same thickness and achieved the goal of greater lifting capacity on lighter boom. The unique manual full proportional control incorporates the advantages of traditional lever control and pilot controlelectric-hydraulic . It not only reserves the merits of safety & reliability of original control structure and low maintenance cost, but also realizes that the working speed of actuating mechanism is only proportional to the opening degree of control valves rather than affected by the load. Furthermore, it has improved the speed-regulation performance. The slewing mechanism has the functions of protecting the crane automatically when the crane is overloaded, reducing the impacts, and activating hydraulic brake when the hydraulic control valve is in neutral position as well as free swing. In addition, it can automatically make boom, wire rope and lifted load slew simultaneously, and minimize the sway of boom and load while the crane starts or stops quickly, and accelerates or decelerates slewing.We have made constant improvements on our products, for instance, adding radiator for hydraulic system and mounting hydraulic oil tank of large capacity on the slewing table. Therefore, the radiating performance of hydraulic system is improved and the continuous working hours are 2~3 times of that of the same trade's products.The crane is fitted with outrigger lamps which can facilitate operation at night.The crane is equipped with high-quality load moment limiter which has such advantages as great precision and complete information shown on the display. In this way, the safe lifting operation can be guaranteed.Technical Features Working performance specificationMax. rated total lifting capacitykg25000Max. load moment of basic boom kN.m980Max. load moment with max. main boomlengthkN.m573Max. lifting height of basic boomm11.5Max. lifting height of main boomm33.8Max. lifting height of fly jibm41.6Working speedMax. speed of single rope on main winchm/min120Max. speed of single rope onauxiliary winchm/min105Derricking time of booms40Telescopic time of booms60Slewing speedr/min0~2.2Traveling specificationMax. traveling speedkm/h72Max. gradeability%40Min. turning circle diameterm20Min. ground clearancemm220Limits for exhaust pollutants and smokeGB3847-2005 GB17691 -2005(Stage III)Oil consumption per hundred kilometersL46Mass specificationDeadweight of crane in traveling conditionkg28930Complete vehicle kerb masskg28800Front axle loadkg6300Rear axle loadkg22630Dimension specificationOverall dimensions(L×W×H)mm13000×2500×3450Base on outriggersm5.36Distance between outriggersm6.1Main boom lengthm10.5~33.3Main boom angle°-2~80Fly jib lengthm8Offset angle of fly jib°0 , 30ChassisModelZLJ5314ClassIIFeature No.ZLJ5314D3.1EngineModelWP10.270Rated powerkW/r/min199/2200Max. output torqueN.m/r/min1100/1200~1600product image/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
