SubscribeRemote-Controlled Machine
GENERAL DESCRIPTION
The MVD Mini Dozer is designed as a very low profile remote controlled machine for multiple use such as; underground mining application, building and construction industry, military and defence missions. Because of its low profile, and remote controlled operation it is suitable for multi purpose tasks and missions.
Based on the South African mining sector expressed need for a small machine, it was initially designed for operations of cleaning slopes after blasting. The operating tool for digging and pushing in front of machine was designed as a dozer blade. It is controlled by a single operator using a simple and convenient hand controller.
The MVD Mini Dozer system weights around 4 tons, and the tests and evaluations in South African mines have showed that the machine is capable of handling a 20 tons of ore per hour, which means that the productivity has been increased by seven times, and in the same time it is greatly increasing the safety of mineworkers.
Strict requirements have been set in the development of this machine, such as: intensive use in the most severe working conditions, ability to work in extremely high temperatures, high performance, modular design, lowest possible maintenance requirements, and environmental protection.
The machine has been developed exclusively according to real demonstrated requirements and user needs for maximum performance and versatility. Because of its dimensions, very good maneuverability, high engine power, and low track-ground pressure, the MVD Mini Dozer can work year round in almost all conditions. The MVD Mini Dozer is easily accessible for inspection, maintenance, trouble-shooting, repair and/or replacement. Maintenance and repairs can be carried out on the field or in workshop conditions. The tools required for repairs and maintenance are standard wrenches and some specially modified tools.
The major components not produced by DOK-ING such as motor and hydraulics are produced by large, international firms thus ensuring long-term availability of spare parts. We have our own in-house service capabilities and can send a team at short notice to any location in the world. We maintain adequate stocks of parts on our premises – both those produced by DOK-ING and outsourced ones.
The MVD Mini Dozer is extremely simple to operate by remote control. Our experience has shown that most people can learn within a period of several days to operate the machine.
The main functional characteristics of MVD Mini Dozer:
- Original design & construction based on extensive experience and study of user needs,
- Sound technology based on an integral approach,
- High mobility and flexibility,
- Safety of personnel,
- Cost-effectiveness and rationalism,
- Excellent efficiency and productivity,
- Low operating and maintenance cost
Test and evaluation program conducted at the Townlands Anglo Platinum Mines in South Africa during 2004 have resulted in 9,610 tons of ore pushed in 500 working hours, while the MVD Mini Dozer was working just in one shift, and with 40 – 50% of it’s capabilities.
