Hitachi ZX260LCH-3G excavator: meet the various working conditions
Hitachi built ZX260LCH-3G excavator is an outstanding representative of Hitachi -3G series of medium-sized excavator. The appearance of sturdy appearance and the construction performance of various harsh environments are particularly noticeable.
Hitachi ZX260LCH-3G excavator: meet the various working conditions
Hitachi built on the Chinese machine condition has been thoroughly studied, the pursuit of power can improve the productivity of ZX260LCH-3G excavator configuration Isuzu CC-6BG1 type four stroke engine, using a large turbocharger with a central combustion chamber and the intercooler, large output power. Moreover, through the perfect combination with the HIOS II hydraulic system, the optimal control of the engine speed is achieved, thereby effectively reducing the fuel consumption.
125kW (167HP) combined with high-power engine and HIOS II hydraulic system, the hydraulic and the engine power can be efficiently used to generate strong mining capacity: the maximum digging force of the bucket, the bucket rod 180kN (18400kgf) maximum digging force 125kN (12700kgf), to achieve a high production efficiency. Excellent turning performance, 12.6rpm can achieve rapid truck loading operations, powerful traction can make the machine in the rugged terrain easy steering operation, but also can walk strongly in the inclined area. In order to minimize the downtime, the components of the hydraulic device and engine are used with excellent performance to enhance reliability.
In order to adapt to the harsh conditions of the Hitachi ZX260LCH-3G operating environment, the lower part of body to walk and work front device used to strengthen the design, improve durability. The H type 6.00m arm, H type bucket with protection plate and stiffener, and H bucket with bottom reinforcement are used. The service life of the front end working device is improved as a whole. WC (tungsten carbide) dissolution was applied to the contact surface of the front end of bucket bucket and bucket, which greatly reduced the wear of contact surface. 2.96M long H bucket pole with protective plate and stiffener. The enhanced B link helps to improve rigidity. At the same time, the hammer hammer threaded seat is installed to facilitate the installation of accessories such as hammer hammer. The front connecting part adopts HN bushing, and the high hardness sintered metal with carburizing and quenching can keep a large amount of grease, and can obtain excellent lubricity and durability. The H bottom bucket is reinforced with 1.3m3 bottom, and the welding parts are protected by wearing plate. Moreover, the transverse wear plate is installed at the bottom of the bucket to improve the durability of the bucket.
In the bad working conditions, the lower part of the walking body bears great stress. In order to improve the long-term reliability of the machine, it is very important to strengthen the lower part of the walking body. Therefore, ZX260LCH-3G excavator walk on the lower part of the structure of the implementation of the strategy of strengthening a greatly enhanced carrier wheel and a tension wheel bracket, reinforcing rail chain guide mechanism (2 per side), H type pedal, a bolt connection reinforced type track plate. By increasing the box size of the X beam and improving the structural design, the performance of the section is increased by 35%. Moreover, the upper and lower plates adopt a whole plate bending forming structure. By reducing the welding position, the strength and quality of the X beam structure are improved.
ZX260LCH-3G excavator pursues the time-saving, labor-saving and low cost maintenance performance, using long life components and filters, helps to reduce maintenance costs, achieve efficient maintenance operations and good economy.
The high performance filter is used to prolong the replacement time of the related oil; the air filter double filter core; the engine oil filter and the oil water separator are arranged on the ground to be checked and replaced.
ZX260LCH-3G excavator pursues more comfortable driving space, functional operating environment to reduce the burden and fatigue of operators, equipped with the function of improving safety, operators can rest assured operation. In the central part of the cab, a high strength closed section structure is adopted. In addition, the overall strength and rigidity of the cab are improved and the safety is enhanced by strengthening the post and thickening the thickness of the rear frame plate in the cab. High quality fiber seats, equipped with headrest and handrails. Set adjustment can be detailed on the tilt and sliding seat, regardless of physical operators, like sitting in the seat as own tailor-made for a long time, even in the face of the work, is not easy to fatigue, achieve superior comfort.
The monitor is set up where the operator does not have to move the line of sight frequently to confirm the machine's condition. The water temperature meter and fuel meter adopt orange pointer and text display screen which are easy to be read instantaneously. Liquid crystal display on the central part of monitor can display hour meter and odometer. Operating mode switch selectable mining and attachment modes. In general mining, hydraulic control will be corresponding switching, in order to achieve smooth operation performance. Easy to operate and reliable switch disks are configured to switch positions immediately after the hand is left the joystick. The mounting surface of the cab is supported by a strengthened frame and mounted on the liquid sealed vibration damping rubber seat, which reduces vibration and cab noise, and achieves good mute performance.
Hitachi ZX260LCH-3G medium crawler excavator used in a wide range of applications with high durability, reliability and superior performance, continuous operation ability, can play in the field of various conditions of power.
Whether it is from the macro perspective, or micro perspective, Hitachi ZX260LCH-3G excavator can be said to be a versatile device, it is not afraid of rough pavement, it is not afraid of rain snow, summer Shaidong frozen it is not afraid, anxious customers, customers want to think, this is the Hitachi ZX260LCH-3G excavator.
