A LEADING HYDRAULIC AND ELECTRONIC SYSTEMS MANUFACTURER OFFERS FIVE WAYS
TO OPTIMISE WORK FUNCTION PERFORMANCE ON A COMPACT WHEEL LOADER
Compact wheel loaders are the workhorse of
the construction jobsite. Each machine must
adapt to a wide variety of tasks, often for critical work
and with little advance planning. Designing a compact
wheel loader that’s adaptable to various demands,
including different operator preferences, variety of work
and range of attachments, can help gain an advantage
over the competition.
Here are five things to consider to optimise work
function performance on a compact wheel loader.
Program with predeveloped software features
For small- to mid-size OEMs, programming all the
intricate work functions in an advanced compact wheel
loader can take significant amounts of engineering time,
not to mention that even when the machine is
functional the systems themselves may not be
optimised for the best performance.
Utilising software with preprogrammed features can
help get a machine to market faster with the latest
high-performing functionalities, and with less effort
from the design team. These software-enabled solutions
cover basic compact wheel loader functions — such as
boom and bucket control, bucket shake, and boom float
— to more advanced features like electronic flow
sharing, electronic end-stroke cushioning, boom
kick-out, maximum boom height limitation, bucket
positioning (aka “Return to Dig”) and electronic torque
limitation for work hydraulic pump.
Design machines with flexibility
Compact wheel loaders are remarkably multifunctional
and flexible machines on any jobsite. They need to be
designed to adapt to a wide variety of working
situations. What is more if the machine design is
inherently versatile, the development process can be
optimised and time to market improved.
One way to achieve this is by integrating components
designed to work together in one cohesive system. This
includes everything from human machine interface
(HMI) to hydraulic systems like vales and pumps, as well
as electronic components such as sensors and
microcontrollers
Furthermore, machine structure can be designed to
easily work with multiple attachments. Implementing
auxiliary hold and prioritisation allows you to hold the
flow and prioritise it above all other valve functions to
ABOVE: According to Danfoss Power Solutions, a compact
wheel loader will operate more efficiently when preprogrammed,
designed with flexibility and simplicity,
aligned to safety regulations and when it offers an
optimised power management system
ensure a constant flow to your attachment, improving
operator control and reducing operator cognitive and
physical stress, while increasing machine productivity.
Optimise power management
Utilisation of electronic torque limiting (ETL) enables the
optimisation of engine power and speed. This can
increase flow capacity while reducing engine RPM, in
turn reducing the machine’s noise footprint and
enhancing the worksite experience for everyone.
Reducing engine speed by 200RPM can reduce fuel
consumption by 5% and cabin noise by 2dB(A).
Making improvements like these are critical not only
to optimise performance but also for creating a positive
operator experience. Minimising noise and vibration will
increase operator comfort and productivity, offering a
competitive edge in the marketplace.
Components with safety features
Once work functions have been designed and
optimised, no one wants to get caught up in safety
certifications. This is a resource drag and can slow time
to market with impact on the bottom line.
Starting with solutions aligned and positioned to
comply with a wide range of safety standards can
significantly reduce the time and complexity of the
development process. Customers will enjoy advanced
machine capabilities without sacrificing safety.
Work with one-stop shop provider
Last, rather than putting resources into fitting all the
varying pieces together without help, work with a
comprehensive partner to simplify the machine design
process. An expert solution provider can help
implement an ideal solution based upon individual
needs. This can help achieve even greater efficiencies
— both in machine performance and in the
development process. iVT
