Land defence Systems

Domestic and International Defence will have increasing dependency on systems that support tenants of ground warfare. Components of the highest quality for integration into high performance precision instruments will play a key role here. WIN plans to leverage its competencies in precision designing and machining, hydraulic and hydro pneumatic components and systems to introduce products/ systems for land defence systems such as:

• Recoil systems for guns
• Elevation & Traversing mechanisms for guns including the power pack
• Hydro Pneumatic suspensions for armoured vehicles

WIN offers deep capabilities, domain knowledge in precision machining, manpower and managerial resources, access to the Indian market and global business practices.

Mining techniques can be classified into two types of excavation - Surface Mining and Sub-surface (underground) Mining. This segment consists multiple equipment like Haulage, Tunneling, Drill and Rock Drills. Wipro is closely associated with global leaders like Sandvik and Atlas Copco for delivering hydraulic cylinders suited to their various Mining equipment.

As the application is severe, and safety being the primary requirement, Wipro's deep expertise in hydraulic cylinder's domain and partnership with global OEMs in design and execution constitute the key to our success.

Features

s well as the standard models, NUMMI has many tipping cylinders designed for specific tasks.

Chip and peat cylinder

LT cylinders are suitable for use in chip and peat transport solutions. Cylinders are available both as single and double acting, for example a model with 4 stages of which the two smallest ones are double acting. This makes it possible to pull back the body after it has passed the tipping roll center. To provide the necessary safety, model range also includes 9 ton hydraulic support legs supplied with locking valves for truck or trailer.

Taylor made cylinders

The starting point of the design is a customer specific need in different operating conditions, in industry vehicles or lifting devices.Typical applications are mining machines, concrete moulds and special vehicles.

Tilt angle can vary from 45 degree to 85 degree.

The famous NUMMI twin ram tipping cylinder is a very strong model, where two cylinders provide a heavy duty lifting power as well as a good lateral stability for tipping.

The most important advantages:

- weight saving compared to front end tipping gears

- small oil volume = fast and safe operation and weight saving

- provides great tipping stability

- low center of gravity = improved stability in the traffic and in the tipping

Stability for multi-purpose bodies

When long bodies with drop-sides are used, or when the rigidity of the vehicle doesn't allow enough lateral support, the strength and sturdiness of NUMMI twin ram type, RT, is the best solution. It is also ideal for long trailers.

Wide range of use

NUMMI RT cylinders are available in various sizes, from two-axle utility vehicles to heavy trucks with 13-metre trailers and to the heaviest earth moving tasks. The maximum load allowed for these models vary from 16 to 50 tonnes.

Approved Nummiquality

To prevent wear and tear, friction on the seals has been minimised by having all ram tubes hard chrome-plated. Each ram has twin seals which keep the ram leak-proof even at extremely low temperatures.

Range:12V & 24V Tank Capacity: 10 to 35 ltrs

NUMMI non-stabilising front-end cylinders are designed for vehicles where lateral stability during tipping is not required from the cylinder and there are no sideloads directed to the tipping cylinder. They have been designed with lifting power as the only aspect. Thus the gear is light, durable and fast.

Moves together with the body

With the ETV model, the cylinder is installed upside down. It is attached to the body with a special jointed bracket in such a way that it is best suited for vehicles equipped with a tipping tank container. ETV-cylinder can be also used in tipper trucks with short body and rigid subframe.

For the most extreme operation conditions

To ensure long working life, all ram tubes are hard chrome-plated.

Stabilising NUMMI front tipping cylinders have been designed not only for lifting but also for giving stability during tipping. For this reason, they are well suited for vehicles with long bodies or tipping semitrailers.

Maximizing front axle payload

In the NUMMI JTC and JTD models, the cylinder is attached to the body with lifting arms which absorb vibrations during transport and allow the flex between the body and the chassis. Because of this attachment method only a small space is needed for the tipping cylinder between the cab and the body. This allows the body to be brought further forward to fully utilise the front axle capacity. The difference between the JTC and JTD models is the type of the attachment on the bottom end.

The NUMMI DFC model is equipped with a cover tube with which it is attached to the body. The cover tube prevents inpurities entering the cylinder during driving. TheDFC model is suitable for long bodies and large loads. The patented cover tube construction and the long overlaps of the cylinder tubes provide a stabilising effect during the tipping.

The NUMMI DFE cylinder is attached from the top directly to the front wall of the body and the front wall needs to be sloped. This attachment method enables the tipping cylinder to be lightweight, giving maximizing payloads. TheDFE model has the similar cylinder tubes as the DFC model so it is also suitable for heavy-duty work which requires increased stability.
