JCB TORQUE LOCK (Optional)

An industry exclusive, JCB Torque Lock enables an operator to dramatically reduce travel time and improve fuel efficiency during roading operations.

Torque Lock incorporates a clutch which, when engaged, enables a direct connection between the engine and gearbox.

By “locking up” the torque converter slippage is eliminated. Torque Lock engages automatically in 4th gear (Powershift models) or “A” mode (Autoshift models).

Not available on Synchroshuttle models.



TRANSMISSION

The JCB Transmissions are designed and built specifically for JCB Backhoe Loaders. They feature synchronised shifting in all gears. Powershuttle between forward and reverse. Ground speeds are designed to maximise production.

JCB optional auto powershift 6 speed transmission features automatic upshift and downshift between 4th, 5th and 6th gear controlled by machine travel speed and incorporates a kickdown pedal to select first gear. The operator may use the Autoshift in manual mode when operator control of shift points is desired. The JCB Powershift transmission allows fast gear changing without losing speed or momentum on gradients. The integral torque converter and electrically operated reversing shuttle help this backhoe loader produce fast cycle times for real wheeled loader performance. Low 1st and 2nd gear ratios provide excellent tractive effort for loading and sitestripping.

CAB

Excellent visibility (and safety) is provided by the extra large tinted glass areas of 6.4 sq m (70 sq ft). Cab frame is ROPS and FOPS approved for maximum operator protection. ISO standard 3471 and 3449 (SAE J1040 and J231).

●

●

●

●

A fully adjustable seat with lumbar support combines with ergonomically positioned controls to minimise operator fatigue.

The in-cab noise levels are the lowest in the business for maximum operator comfort.

A radio location is provided as standard plus twin speakers for stereo sound.

Cab provides easy access through a two door frame. Rear side windows open either partially or fully for extra ventilation.

Standard features include: lap seat belt, 3 speed fresh air/recycle heater, front and rear screen wash/wipers, front and rear horn, exterior mirrors, and flat easy-clean floor.

●

●

●

The instrument panel is positioned to the right-hand side for ease of viewing from either the loading or excavating position and has an optional lockable cover for vandal proofing. Engine speed, fuel and coolant temperature gauges, (and clock on cab builds) are mounted in the panel.

A high performance air conditioning system is optionally available on turbo builds providing the operator with a cool working environment when working in high temperatures.

Mechanical suspension seat gives the operator a comfortable operating position.

An optionally available heated air suspension seat gives the operator the ultimate comfort with automatic compensation for weight.

JCB PRECISION CONTROL (Optional)

JCB Precision Control offers smooth, low effort and productive backhoe operation, while reducing operator fatigue. Excavator control joysticks are integrated into the seat, providing increased legroom, improved job visibility and hydraulic excavator ergonomics. A proportional switch is mounted in the joystick to operate JCB’s Extradig. An optional joystick mounted switch is also available to operate auxiliary attachments. The low effort mechanical loader control incorporates an optional proportional switch to operate loader mounted attachments.

Best in class hydraulic modulation combined with the greatest digging performance, means that the JCB Precision Control is unmatched in any backhoe loader. This option is available on open centre system only.

BRAKES

The JCB braking system ensures effective, fade-free braking. The self-adjusting, multi-disc arrangement is inboard mounted and is oil immersed for minimum maintenance and a long operating life.

●

●

Four wheel braking.

All machines are fitted with servo assisted brakes as standard for low effort braking.

●

●

●

●

Twin brake pedals provide tighter turning circle and enhanced steering control on slippery ground.

Automatic compensation ensures ‘straight’ machine braking.

Disc diameter: 220 mm (8.7 in). Friction area: 129,000 sq.mm (200 sq. in) per brake.

The integral park brake is a ball and ramp, oil immersed type located within the transmission and will hold the machine on

1:3 gradients. It is an over-centre type, adjustable within the cab, with transmission disconnect to prevent premature brake pad wear. There are 5 friction brake discs having an outside diameter of 127mm (5 in). Frictional area per brake disc is

47.65 sq. cm (7.39 sq. in) giving a total frictional area of 476.5 sq. cm (73.9 sq. in).

TYRES

HYDRAULIC SYSTEM

The standard Open Centre system uses twin gear pumps and Hydraulic Speed Control (HSC) with a power modulation valve that automatically varies hydraulic power to match digging conditions for extra performance and power.

The alternative Closed Centre system uses a single variable flow axial piston pump. This load sensing system matches flow to work demand improving productivity and efficiency.

Both systems incorporate:

●

●

Ergonomically positioned levers allowing excellent control of the loader and backhoe.

A full flow 10 micron filter ensures that oil stays free of contaminants.

SERVICE CAPACITIES

JCB SMOOTH RIDE SYSTEM (Optional)

The JCB Smooth Ride System (SRS) consists of a dry nitrogen and oil filled accumulator installed in line with the loader lift cylinders.

When activated, the Smooth Ride System allows the loader arms to float. This action counteracts variations in road or site surfaces and provides the operator with a smooth ride. The JCB Smooth Ride System is manually controlled, via a rocker switch on the instrument panel, for maximum benefit and user flexibility.

JCB POWERSLIDE (Optional)

Exclusive to JCB, this option enables the excavator’s sideshift carriage to be hydraulically powered across the rearframe by the operation of a pedal or joystick mounted proportional switch (Precision Control) in the cab.

With this feature there is no need to “push” the carriage across with the bucket avoiding ground damage and the need to relocate the whole machine.

This option is available on open centre system only.



BACKHOE BUCKETS – Standard Profile Bucket

JCB backhoe buckets are designed specifically for use on JCB machines with pin positions to maximise tearout, load retention and straight wall digging characteristics.
