USED JCB

JCB is launching the new 8085 ZTS midi excavator, offering increased torque, reduced fuel consumption, upgraded controls and a host of detail improvements. Though similar in overall dimensions to the JCB 8080 ZTS it replaces, the JCB 8085 ZTS is more productive, yet promises lower operating costs and reduced emissions.

Efficient Power

The JCB 8085 ZTS is powered by a Tier 3 compliant, turbocharged 2.2 litre Isuzu engine offering 43kW (57.6hp), a slight increase of two per cent compared to the JCB 8080 ZTS. Torque rises by 13% to 220Nm, yet arrives 200rpm earlier, at 1,600rpm. By providing more power and torque at lower revs, in tests the direct injection engine uses up to two litres per hour less fuel, reducing CO² emissions and cutting running costs.

Auto-idle and one-touch-idle functions contribute to a further reduction in fuel consumption, by dropping engine revs to idle speed when the machine is not in use. The machine also makes use of JCB’s Advanced Management System (AMS) and a three-mode power selection control, providing light, standard and heavy modes depending on ground conditions.

Robust Design

The 8085 ZTS has a similar digging envelope to the 8080 ZTS, with a maximum digging depth of 4,214mm and a maximum dumping height of 4,703mm.

Improvements have been made to the hose routing through the king post for increased protection. All hydraulic circuits on the digging end are supplied as standard with quick release connectors and dust caps.

In line with EN474 legislation the 8085 ZTS will be available with a choice of hose burst control valves on the boom and dipper, or a full hose burst kit on the boom, dipper and dozer piping. This ensures that customer machines will be factory-ready for all lifting applications and attachments.

Operator Comfort

In the cab, the 8085 ZTS has improved control pods with new wrist rests to provide increased operator comfort. Short travel joysticks are used and the machine is equipped with a two-speed tracking button in the dozer control lever. The tracking pedals and levers have also been redesigned to improve operator comfort, while the boom offset and auxiliary control have been redesigned into a single left-right rocker pedal to the right of the track controls.

The AMS system incorporates a large LCD display screen with three menu modes, for settings, diagnostics and calibration. Customers can specify optional air conditioning and the machine is available with a choice of three seats and a choice of ISO or ISO/SAE control patterns.

Service Access

The revised hydraulic valve block, which is now available with a choice of 9 or 10 spools, has been relocated into the side compartment alongside the engine. This results in shorter hose runs from the valve block to the dig end, reducing the number of hoses running under the cab floor. An access panel in the side of the cab ensures that technicians can get to hoses on both sides of the valve block.

The fan and air conditioning belts have been relocated for improved access, while all check and fill points are positioned for easy reach from ground level. The exhaust has been isolated from the engine, minimising vibration and reducing noise both in the cab (to 73dB) and outside the machine (to 98dB).

By moving the hydraulic valve block to the engine compartment there is now more room in the rear access panel for remote service points and the cooling pack. Main service intervals remain at 500 and 1,000 hours.

Increased Control

The 8085 ZTS is one of the first compact excavators in the industry to be offered with the option of electronic proportional auxiliary controls. These thumb operated controls provide greater precision in a number of applications and with a variety of attachments, including a tilt rotator which increases the versatility of the machine.

Customers can choose between a nine spool valve block, for single or double acting hydraulic flow, or a 10 spool block for attachments that require the additional low-flow circuit. Those machines that are fitted with double acting pipework have a single to double acting ball valve tap control to prevent accidental operation of a single acting attachment in the wrong direction.

The 8085 ZTS also has the option of bucket to grab changeover valves on the auxiliary high flow circuit for those customers who require a hanging grab or similar attachment.

Modern Appearance

As befits its top of the range status, the 8085 ZTS will be one of the first machines to feature JCB’s new corporate branding and identity. The curved pod profiles provide excellent visibility all around the machine, while maintaining a family appearance with other JCB mini and midi excavators.

The machine bears the latest JCB decals, which have been designed to increase the visibility of the brand, while allowing customers more space for their own livery. As part of a 15 machine compact excavator line-up, the 8085 ZTS provides customers with increased productivity and performance, while reducing running costs and emissions.
