Bulldozer trainer

P.N.:GTMT-0007

Product description

The hydraulic bulldozer is a self-supporting earth-moving transportation construction machine which is composed of a belt tractor or a tire-type basic vehicle as a carrier, equipped with a bulldozer working device and an operating mechanism. It is widely used in construction machinery, applicable for transport, accumulation, backfill, leveling, excavation and soil loosing and other operations in large-scale earthwork construction projects, such as construction sites, road construction, water conservancy projects, defense works, construction of road cuts, sites leveling and open-pit stripping, etc.

Basic experiment

A. Experimental program

1. The structure, working principle and disassemble experiment of hydraulic transmission components.

2. Hydraulic bulldozer mechanical demonstration control experiment.

3. PLC software simulation demonstration and control experiment.

4. Programmable logic controller (PLC) electrical control experiment: Machine-electricity-hydraulic integrated control experiment.

B. Experiment content

1. Structure, working principle and disassemble experiment of hydraulic transmission components.

1) Mapping and analysis of mechanical components

2) Learning and analysis of the principle of hydraulic control system

2. Hydraulic bulldozer mechanical demonstration control experiment

Shovel - Earthmoving - Unloading – No-load return

3. Programmable logic controller (PLC) electrical control experiment: Machine-electricity-hydraulic integrated control experiment.


Main feature

1. The experimental bench is made of cold-rolled steel plate (sprayed and treated with anti-corrosion treatment). With bench-top structure, control and operation are integrated.

2. The electrical operation control is under-mounted and the hydraulic station is placed in the main cabinet of the hydraulic platform. The overall structure is compact, coordinated, and the layout is practical, available for 4-6 people experiments.

3. The full-metal structure of bulldozer is reduced in proportion to the actual object. The hydraulic system is started during the experiment to simulate the operation of the machine according to the experimental requirements.

4. The bulldozing machinery is manufactured according to the structure of the physical object and the reduced proportion, which can truly reflect the actual working conditions of the machine, so that the students can profoundly understand the structure and working principle of each part of the machine in the experiment.

5. Experimental control: manual control and automatic control.

6. The experimental components use pressure resistant hose, the pressure up to 25Mpa.

7. With three-phase leakage protection, the output voltage 380V/220V, power supply disconnected when more than 30mA leakage happens;

electrical control uses DC 24V power supply with over-voltage protection, prevent the device damage by wrong operation.
