JCB 437 Chargeuse sur pneus

Un processus de qualité

The JCB 437 wheel loader’s articulation joint has a heavy-duty box section, a heavy-duty centre pin and oversized bush, as well as twin taper roller bearings on the bottom box joints. This setup can easily tolerate vertical and horizontal loadings.

Finite element analysis, as well as extensive endurance and rig testing ensure superior structural strength and durability. Cold cell testing guarantees starting performance down to -20°C.

High tolerances and accurate location of pins and bushes are assured with JCB’s precision machining techniques. State-of-the-art manufacturing processes like robot machining, precision paint technology and innovative assembly techniques help to achieve the very highest levels of build quality.

A solid cast rear counterweight protects the rear of your JCB 437 wheel loader – including the rear lights and cooling pack – from damage. Hoses are neatly routed and clamped through the articulation joint, well away from any pinch points.

The new front chassis is more durable than ever; it's been strengthened with additional ribs and gussets for maximum service life. For additional protection, there are impact-resistant fender edges and trims fitted.

This wheel loader has integral steel fluid tanks for the ultimate in leak protection: a far superior solution to the plastic tanks favoured by some competitors.

COMMANDE PLUS

The ROPS structure on the 437 wheel loader is redesigned; A pillars are the same width as the rear of the cab, providing a larger interior and panoramic front windscreen. Switches and auxiliary controls are now on the right-hand A-pillar.

There are two full colour LCD screens to navigate the operating menus, one of which can double as a monitor for the optional rear-view camera. Using your JCB’s simple, dedicated menu interface is easy with an intuitive optional rotary controller.

As standard, the JCB 437 wheel loader is equipped with heated external mirrors that can be electronically adjusted from inside the cab. Convex mirrors are also available to give the best possible field of vision.

An all-new air venting system boasts nine demisting vents and six operator vents to maintain visibility and operator comfort at all times. It also operates at a reduced noise level.

All controls are seat-mounted, even moving with the seat suspension. You can also select the control system that’s best for your operators: choose from single lever joystick or multi-lever configurations, all using electro-hydraulics for the ultimate in precision.

After extensive research into operator ergonomics, we’ve devised the Command Driving Position, which boasts the very optimal control layout for a multitude of different driver shapes and sizes.

CONDUIRE EN SÉCURITÉ

On the new JCB 437 wheel loader, you’ll find the rear-view mirrors mounted in front of the A-pillars for improved visibility. Interior mirrors, heated exterior mirrors and bonnet mirrors combine to offer excellent views all around your wheeled loading shovel.

Access steps on this loader are inclined and equally spaced, complemented by well positioned grab handles for three points of contact at all times. Non-slip walkways and additional grab handle options allow for safe movement around the machine.

Door hinges are now mounted on the A-pillar of the JCB 437; this simple change has created much better access via a larger and wider door aperture. It also means you can access the rear of your loader more safely.

Full fender coverage flaps have been carefully designed to keep forward spray to a minimum for all tyre options. This increases safety and decreases debris build-up on your wheel loader.

Engines fitted with a DPF can pose an increased fire risk because extreme heat can be created in regeneration mode. The new 437 doesn’t use DPFs, so this is no cause for concern.

The cab is isolator-mounted, compliant with ROPS/FOPS standards, and positively pressurised against dust. You can choose from fresh air or carbon filters as well.

EFFICACE PAR CONCEPTION

The JCB 437 wheel loader's Auto Idle feature returns the engine to 700rpm after 30 seconds of inactivity. Eco Mode caps engine speed at 1800rpm for reduced fuel consumption. Productivity nonetheless remains formidable.

A hydraulic cooling fan automatically reacts to ambient temperature and adjusts the fan speed to optimise energy and reduce fuel consumption. An additional benefit of this setup is lower noise levels.

Our torque lock-up 5-speed transmission option gives 100% efficiency in gears 2 to 5 for improved fuel consumption on your wheeled loading shovel. Closer gear ratios provide lower engine speed in each gear.

Wheel speed braking means brakes rotate at the same speed as the wheels for heat and drag reduction, as well as improved economy. Unloaded spool valves in the valve block, meanwhile, mean that arms lower under gravitational forces, improving efficiency.

JCB’s innovative variable displacement pumps feed a load-sensing valve block which only consumes power on demand, providing precise, efficient loader control.

JCB Smoothride load suspension limits shock loadings and therefore reduces material spillage and structural stress, as well as increasing operator comfort. The speed of engagement is adjustable from within the cab using the latest state-of-the-art Command Plus controls.

INTERVALLES LONGS DE FAIBLE ENTRETIEN

It’s easy to get to the engine on a new JCB 437 wheel loader with a large automatic opening single-piece bonnet. Accessing the diesel and DEF tanks is similarly straightforward via the lockable grille at the rear of the machine.

Heating and ventilation filters are conveniently located behind an external access panel. You can check washer fluid level, engine oil and coolant from inside the cab, with all other routine checks and grease points located at ground level.

A cyclonic engine fan scavenge filter provides four times the filtering capacity of a standard air filter. It's a longer life system, with fewer components and a higher level of efficiency, making for better engine protection.

Most Tier 4 Final/Stage IV engines use a Diesel Particulate Filter (DPF) that can cost a lot of money and time when it needs replacing. The Cummins engine is DPF-free, reducing your servicing and running costs.

By using top components in the JCB 437 wheeled loading shovel (Cummins engine, ZF transmissions and axles, Rexroth pumps and Parker valve blocks), we’ve built in long service life as standard.
