The wheel loaders are seeing fresh traction due to the Indian government’s infrastructure push that includes proposed monetisation of public infrastructure assets, including national highways, power grids, freight corridors of railways, airports, and oil and gas pipelines. Wheel Loaders are now designed to handle a variety of jobs on your worksite from material handling and truck loading, general construction, tunneling to stockpiling. The heavy-duty quarrying production work in mining is also adding to the demand. The buyers now want wheel loaders that deliver higher productivity and lesser operating costs, along with enhanced servicing across their machine’s work cycle. The 3-ton class and 5-ton class of wheel loaders are in most demand in the Indian construction market. The manufacturers of wheel loaders are keeping a keen eye on the advancements for higher machine availability and fuel efficiency. Discussed below are different types of wheel loader being manufactured.
Different types of wheel loaders manufactured in India
Wheel loaders with hydraulic pressure measuring points
Modern wheel loaders come with centralized hydraulic pressure measuring points for easy checks and troubleshooting. These models come with variable displacement pumps and with different types of mode selectors [Automatic, Semi-Automatic and Manual] which make them more productive and fuel-efficient. The optimized design of the buckets provides a greater loading capacity and lesser operating cycle time with the synchronized flow. Pilot control single lever makes the machine easy to operate. The machines are also equipped with GPS which provides accurate data which helps the owner evaluate the performance of the machine. Added to the loading usefulness is that the machine comes with a long lifecycle and low operating costs. The machines have a standard bucket capacity of 1.7 cu m. Ergo-power electric control gearbox in the machines enables smooth and comfortable shifting. The cooling fan with temperature control in the machine is driven by a hydraulic motor.
Wheel loaders with an increased shovel capacity
Newer wheel loaders come with an increased shovel capacity of 1.1 cum that are befitting for earthmoving applications. With a hydraulic oil change period of 2000 hrs, these machines not only take care of your earthmoving applications but also use very less fuel. It has got a maximum bucket capacity of 3.1 cum for crusher application and 5 Cum for coal mining application. In addition to its maximum operating weight of 17,880 kg, the machine is also equipped with a Loader Coach and a Loader Productivity Management System. The limited-slip differential in this machine is ideal for working in tough terrains. The Z-bar loader geometry facilitates enhanced penetration into the pile, as well as delivering high breakout forces, good roll-back angles and faster cycle time. In addition, the Electronic Management System allows for a progressive clutch cut-off giving effective loader control while the powerful twin variable displacement piston pumps enhance multi-function capabilities. The large cabin offers a stylish, modern central dash display that combines analogue dials and a color LCD screen that displays the health status of the machine, service requirements and operating information.
Wheel loaders for face loading, heavy-duty block and log handling
New generation wheel loaders come with N load sensing hydraulics that have been designed to enhance the responsiveness of the attachment and reduce cycle times by improving the lifting and lowering speed of the boom. The machine’s range of purpose-built attachments makes it fitted for applications such as block handling, logging and slag handling. Form one solid and reliable unit with attachments that are ideally matched by size and design to your machine’s parameters – including link-arm geometry, and breakout and lifting forces. For tunneling applications, the wheel loader can also be equipped with a Side Dump Rock bucket. To increase your productivity, the long boom configuration enables the loading of a 65-tonne truck in no more than six passes. The bucket is easier to fill and minimizes spillage, due to new convex sides and the improved spill guard. To enhance productivity and absorb shocks, you can use Boom Suspension System, which automatically engages depending on gear and speed. The cab has a rear-view camera and new rearview mirrors
Wheel loaders with Hydrostatic Transmission
Modern wheel loaders use hydrostatic transmission (HST) for ease of use and controllability. The main advantage of hydrostatic transmission is the exceptional fuel saving offered over its hydrodynamic transmission. Minimal force is required to operate levers and pedals, enabling improved controllability. The machine has better gradability on hills, improved digging capability, and maximum visibility enables the most comfortable operation possible. The operators can choose between 2 modes according to job site requirements. Standard mode is preselected and sufficient for ordinary work. On the other hand, the power mode gives extra power when needed. It is particularly useful on sites where strong traction or acceleration is required. The “Active Engine Control System” in the machine plays a key role in achieving economical operation. Strategically positioned sensors detect movements throughout the machine and adjust engine speed accordingly to eliminate energy losses to maximize fuel conservation. The cab is both comfortable and functional with a series of features aimed at reducing operator fatigue.
Medium-sized wheel loaders for material handling
Newer models are designed specifically to handle all the jobs on your worksite from material handling and truck loading, to general construction, to stockpiling. These machines are designed to handle all the jobs on your worksite from material handling and truck loading to general construction. Engine Idle Management System (EIMS), Auto Engine Idle Shutdown (EIS), variable speed fan and load sensing hydraulics help result in the low fuel consumption on this machine. Intuitive controls and excellent visibility provide a comfortable working environment for efficient all-day operation. Electronically controlled, hydraulically driven variable speed fan adjusts to meet the varying cooling requirements of the machine. This results in a reduced average fan speed, lowering fuel consumption, noise levels, and radiator plugging. The spacious cab in these machines features easy, intuitive controls and excellent visibility which provides a comfortable working environment for efficient all-day operation. Pilot-operated hydraulic implement controls deliver comfortable, low-effort operation. Two single-axis levers or one joystick are available. Both arrangements are equipped with kick-down switches.
Conclusion
Discussed above are different types of wheel loaders being manufactured. Manufacturers are looking to minimize unnecessary loss of power, thereby, boosting efficiency and generating sufficient power for digging, steering, and combination movement.
