DEVELON

A NEW MODEL WITH NOVEL FEATURES

- Increased productivity and improved fuel economy are attributed to the electronic optimization of the hydraulic system and the DEVELON engine (Tier II).
- Improved ergonomics increases comfort and excellent all round visibility ensuring a safe and pleasant working environment.
- Improved reliability is achieved through the use of high performance materials combined with new methods of structural stress analysis. It leads to increased component life expectancy, thus reducing running costs.

PERFORMANCE & PRODUCTIVITY

- The new travel motor and transmission control in the drive line provide comfortable travel due to increased smoothness, improved hydraulic retarding and improved gear shifting.
- The front axle offers wide oscillating and steering angles. The transmission is mounted directly on the rear axle for protection and optimum ground clearance.
- The new disc brake system works directly on the hub instead of the drive shaft to avoid planetary gear backlash. This eliminates the rocking effect associated with working free on wheels. The new axle is designed for low maintenance and the oil change intervals have been increased from 1,000 to 2,000 hours further reducing owning and operating costs.
- A rigid, welded frame provides excellent durability. Efficient hydraulic lines routing, transmission protection and heavy duty axles make the undercarriage perfect for wheel excavator applications. Both outriggers and dozer blade are pin type for maximum flexibility. An optional work tool restraint bar is available.
- The pin type design allows the outriggers to be mounted on the front and/or rear for maximum operating stability when digging or lifting.
- The pin type design allows the dozer blade to be mounted on the front and/or rear and is used for leveling, clean-up work and for stabilizing the machine during digging applications. The large dozer bottom and parallel design provide minimized ground pressure.

DURABILITY & RELIABILITY

- A highly lubricated metal is used for the boom pivot in order to increase the lifetime and extend the greasing intervals to 250 hours. A rolled bushing, with very fine grooves, has been added to the arm, bucket, dozer, and
outrigger pivot; so greasing is only required every 50 hours.
- A polymer shim is added to the bucket, dozer, and outrigger pivot to promote extended pin and bushing life.
- Large reinforced protective covers have been adopted to completely protect the Dozer & Outrigger cylinders from falling stones etc, while the machine is operating.
- A cast counterweight has been adopted to minimize deformation by external impact. In addition, operating stability has been increased by use of a low center of gravity design.
- The use of LED type stop lamps ensures considerably improved average service life compared to the existing standard filament bulbs. Furthermore, the faster lighting speed helps contribute to accident prevention.

FUEL EFFICIENCY

- Engine & pump matching, the new technology of DEVELON, fully resolves problems; low respones time of the system, unnecessary fuel consumption. Matching response time between pump and engine efficiently reduces unnecessary fuel consumption as well as exhaust fumes.
- The pump continues to supply flow even when the maximum pressure on the system is reached due to severe working environments and large workloads. Relief cutoff technology of DX140W prevents transfer of unnecessary flow to maintain powerful working level at the maximum value while reducing consumption of fuel.
- When operator takes a break and leaves the control joystick fixed, both of the engine and the pump are kept in standby mode and prevents unnecessary fuel consumption.

EASY MAINTENANCE

- The engine oil filter offers a high level of filtration allowing the oil change interval to be increased to 500 hours. It is easy to access and is positioned to avoid contaminating the surrounding environment.
- The protection of the hydraulic system is made more effective by the use of glass fiber filter technology in the main oil return filter. This means that with more than 99.5% of foreign particles filtered out, the oil change interval is increased.
- The large capacity forced air cleaner removes over 99% of airborne particles, reducing the risk of engine contamination and making the cleaning and cartridge change intervals greater.
- High efficiency and large capacity water separator protect the engine by removing most moisture from the fuel.
- Since independent air-conditioner filter for internal and external machine, fresh air is supplied indoors.
- Radiator and oil cooler in high capacity and high efficiency are attached so that the best cooling function can be maintained all the time.
- Stainless tube is applied to oil cooler piping to prevent oil leakage.
- The muscular appearance and internal reinforced board in attachment type realize both good appearance and solid strength.
- As battery cover is applied, shortage is prevented and customer is protected from unexpected accident.
- As anti-skid cover punched in asterisk shape is added on the upper part, slippery is prevented for service to increase safety.
- Thanks to the fuel tank with the maximum capacity of 280 liter in the same grade, consecutive work time is elongated.
