Especificaciones técnicas
Chasis
| Frame | Designed and manufactured by XCMG,it is made of high strength steel with optimized load-bearing structure design and anti-torsion box-typed structure. Outrigger boxes are separately located between 2nd and 3rd axles and at the rear of the frame.Front and rear towing eyes are available. |
| Outriggers | 4 Four outriggers arranged in H-shape are hydraulically controlled by control levers.There is an outrigger control station located on each side of the chassis,and there is a level gauge on each control station.The outrigger movements can be simultaneously or separately controlled on either side of the chassis.There is a check valve fitted in each outrigger cylinder,and a double-way hydraulic valve fitted in each jack cylinder.Outrigger float diameter:φ450 mm.Reaction force of outrigger at max.lifting load:490 KN |
| Engine | D10.38-50,in-line,6-cylinder,water cooled,electric control diesel engine,made by SINOTRUK,with rated power of 276 kW/2000 rpm and max.torque of 1560 Nm/1200-1500 rpm,compliant to China V emission standard. SC10E380Q5,in-line,6 cylinders,water cooled, electric control diesel engine.Shanghai Diesel Engine,with rated power of279 kW/1900 rpm and max.torque of 1620 Nm/1100-1400 rpm,compliant to China Vemission standard.Fuel tank capacity:320 L |
| Transmission | 9-speed transmission with synchronizer; flexible shaft mechanical control. |
| Axles | High strength axles,designed by using the foreign advanced technology and made by famous manufacturer, have reliable performance. |
| Suspension | Rubber spring suspensions with V-type push rods are adopted for rear suspension system,leading to improved chassis stability and reduced tire wear. |
| Tires | 315/80R22.5,×12 Spare tire 315/80R22.5,×1 |
| Braking system | Service brake:foot pedal operated double-circuit air pressure brake.The 1st circuit acts on wheels of Axle 1 and 2;the 2nd circuit acts on wheels of Axle 3 and 4.Parking brake:spring-loaded brake,acting on wheels of Axle 3 and 4.Auxiliary brake:engine exhaust brake,which is safe and reliable,and will prolong the service life of brake lining. |
| Steering system | Mechanically steering mechanism with a hydraulic booster. |
| Driver's cab | Full-dimension cab is equipped with radio,adjustable seat,steering wheel,large-view rear mirror and manual window lifter. Air conditioning and heating are standard. |
| Electrical system | 24VDC,two sets of 12 V battery in series. Generator:28.5±0.3V-70 A |
Superestructura
| Frame | Designed and manufactured by XCMG, made of high strength steel. |
| Hydraulic system | Hydraulic pump: quadruple pump driven by the chassis engine, fixed-displacement pump used for lifting, luffing and telescoping operations. Control valve: load sensitive proportional multi way change valve controlled by pilot hydraulic oil, which is integrated with impact resistance valve and cavitation-proof valve.Oil circuit: there is an air cooled hydraulic oil cooler equipped to effectively reduces the oil temperature. Oil filters: suction filter and return filter |
| Control way | Stepless speed regulation.Pilot hydraulic proportional control through the leftand right levers is used for controlling the superstructure. All crane movements are controlled by the hydraulic pump and proportional valve. |
| Main winch | Hydraulic control is used for speed regulation. The system is driven by a hydraulic motor through a planetary gear reducer, with a normally closed brake, a balanced valve and a Lebus-type grooved drum equipped.It features high speed with a light load and low speed with a heavy load. |
| Slewing system | A single-row, four-point contact-ball external toothed slewing bearing is driven by the hydraulic motor, with built-in planetary gear reducer and constant-closed brake equipped, and may continuously slew 360°. Power control and free swing function as well as stepless speed regulation are available. |
| Luffing system | A front support double-acting hydraulic cylinder is equipped for luffing operation, with a balance valve fitted. |
| Operator's cab | New steel cab with a full-view windshield, safety glass, sun shield, sliding door and adjustable operator’s seat. Crane control levers are integrated into armrests.A pull-out step is available to make it easy and safe to enter and exit the cab. Wipers are fitted for the windshield and roof window; standard controls and indicators are ergonomically arranged in the cab.Heating and air conditioning are available. |
| Safety devices | Hydraulic balance valve, hydraulic relief valve,hydraulic double-way valve, LMI, spring centering system for control levers, lowering limiter for preventing wire rope from over-releasing, and anti two block at boom head for preventing wire rope from over-winding. |
| Hook blocks | 50 t 4.5 t |
| Counterweight | 5.5 t+1t |
Sistema Boom

Las cargas nominales totales indicadas en las tablas de carga nominal corresponden a la capacidad máxima de elevación cuando la grúa está instalada sobre terreno firme y nivelado, incluyendo el peso del gancho y las eslingas. El peso de estos dispositivos debe restarse de la carga nominal de elevación.
El radio de trabajo mostrado en las tablas de carga nominal es el radio cuando la carga se eleva del suelo, y es el valor real incluyendo la deflexión de la pluma con carga. Considere la deflexión de la pluma antes de iniciar la operación de elevación.
La operación de elevación solo está permitida cuando la fuerza del viento es inferior a grado 5 (velocidad instantánea del viento de 14,1 m/s, presión del viento de 125 N/m²).
Antes de iniciar la operación de elevación, el operador debe conocer el peso de la carga a elevar y su rango de trabajo, y luego seleccionar las condiciones de trabajo adecuadas. Nunca opere la grúa más allá del límite indicado en la tabla. Utilice el valor inferior de la tabla cuando la longitud de la pluma o el radio de trabajo se encuentren dentro del rango de valores.
No extienda la pluma más allá de los ángulos indicados en los diagramas de alcance, ya que podría volcarse.
La pluma debe extenderse según el código telescópico indicado por dígitos, que representa el porcentaje de secciones de la pluma extendidas.
