Glory pushes the national machine heavy industry high horsepower bulldozer

Luoyang Company is one of the earliest manufacturers in China to develop and manufacture bulldozers. Over the years, with its superb military technology, it has continuously developed a series of high-performance bulldozer products that meet the national conditions and market demand.
Recommended for everyone today: YD320 hydraulic drive crawler dozer.

●Powerful power system

It is equipped with Cummins' three-emission engine, which has large output torque, strong power, low fuel consumption rate, and energy saving and environmental protection.

● Mature transmission system

The single-stage single-phase three-element hydraulic torque converter can realize the non-stop shifting and effectively improve the working efficiency; the hydraulic transmission improves the vibration absorption and shock absorption performance, optimizes the adaptability of the torque output and the external load, and improves the equipment. The service life.

● Convenient control system

The control system adopts the most advanced servo mechanism, which has fast response and high precision. It can effectively reduce the labor intensity of the driver and fully meet the refinement requirements of the operation.

●High-intensity host structure

The welding of the core structural parts (frame) adopts the special tooling fixture + machining center method, which effectively controls the influence of welding deformation. The box body processed by the machining center, the left and right inner and outer half shells also ensure the critical size of the end drive. The reliability of the whole machine is significantly improved.

● superior security

Equipped with an electronic monitoring system to achieve fault alarm display, fully ensuring the safety of driving.

●High cab

The new cab has an open view, beautiful and stylish appearance, reasonable interior layout, good sealing and shock absorption effect, and comfortable driving.

● Convenient maintenance

The hydraulic filter increases the alarm device, promptly reminds the user to clean the filter element or replace the hydraulic oil; the oil, water and other daily maintenance points are humanized, and the inspection and maintenance are convenient.

YD320 meets the construction requirements of harsh working conditions and is suitable for the operation of large construction sites such as mines, coal yards, water conservancy, road construction, airports and ports.

"Gravity Die Casting. A permanent mould casting process, where the molten metal is poured from a vessle of ladle into the mould, and cavity fills with no force other than gravity, in a similar manner to the production of sand castings, although filling cn be controlled by tilting the die."

Gravity Die Casting

Sometimes referred to as Permanent Mould, GDC is a repeatable casting process used for non-ferrous alloy parts, typically aluminium, Zinc and Copper Base alloys.

The process differs from HPDC in that Gravity- rather than high pressure- is used to fill the mould with the liquid alloy.

GDC is suited to medium to high volumes products and typically parts are of a heavier sections than HPDC, but thinner sections than sand casting.

There are three key stages in the process.

  1. The heated mould [Die or Tool] is coated with a die release agent. The release agent spray also has a secondary function in that it aids cooling of the mould face after the previous part has been removed from the die.
  2. Molten metal is poured into channels in the tool to allow the material to fill all the extremities of the mould cavity. The metal is either hand poured using steel ladles or dosed using mechanical methods. Typically, there is a mould [down sprue" that allows the alloy to enter the mould cavity from the lower part of the die, reducing the formation of turbulence and subsequent porosity and inclusions in the finished part.
  3. Once the part has cooled sufficiently, the die is opened, either manually or utilising mechanical methods.

Advantages

  • Good dimensional accuracy
  • Smoother cast surface finish than sand casting
  • Improved mechanical properties compared to sand casting
  • Thinner walls can be cast compared to sand casting
  • Reverse draft internal pockets and forms can be cast in using preformed sand core inserts
  • Steel pins and inserts can be cast in to the part
  • Faster production times compared to other processes.
  • Once the tolling is proven, the product quality is very repeatable.
  • Outsourced Tooling setup costs can be lower than sand casting.
