The brand new JCB 8029 CTS mini excavator is our first-ever conventional tailswing machine in the current 2.5-3.5 ton class. With a transport weight of 2.7 tons, it’s one of the largest excavators you can tow behind a 3.5 ton vehicle. It’s similar in many ways to our 8025, but it’s been uprated in key areas..
This JCB mini digger’s power is provided by the new Perkins 400 series Tier IIIa, a transverse 25hp (18kW) motor that delivers 21581lbf (96kN) of torque at 1800rpm. A tailswing of 1ft 5in (470mm) more than the 8025 ZTS, combined with a very low center of gravity, provides a 19% greater lift capacity than the market leader.
At the 8029 CTS compact excavator’s dig end, our box-fabricated boom and dipper is capable of 8ft 9in (2.74m) dig depth, 15ft 6in (4.77m) reach and 10ft 5in (3.22m) dump height. Excellent bucket rotation and class-leading tear-out forces mean great productivity. Versatility-wise, you can easily attach hammers, compactor plates and more.
A brand new undercarriage, meanwhile, uses 3 bottom rollers, 1 top roller, plus heavy duty track idler guides and grease tensioners.
All of which is just the beginning of the JCB 8026 CTS mini excavator’s benefits.
Durability and Serviceability
Just like our 8025, the new JCB 8029 CTS mini excavator is designed to meet customer demands for unrivaled service access and long 500-hour service intervals.
Externally, there’s now a robust black cast counterweight to protect the rear and we’ve lowered the turret height by 1.3in (35mm) for added stability.
We’ve also improved the tracks on the 8026 CTS JCB mini digger. 9.8in (250mm) Bridgestone short pitch tracks reduce noise and vibration, and are highly durable.
Single side grease points on the excavator arm pivot pins simplify greasing. Then there’s excellent access to the hydraulic valve block under the side-opening hood, plus we’ve used the latest O-ring face seals throughout this compact excavator’s hydraulic system for durability. The two gas assisted gull wing bonnets give excellent engine access.
Quality Above All
The lower door is made from steel, averting costly glass breakages.
Our top-mounted boom ram is perfectly protected when loading lorries and skips
The 8018 CTS uses the very latest sealing technology – O-ring face trapezoidal seal hydraulics minimise leaks.
To optimise durability and service life, we’ve fitted replaceable steel bushes to the kingpost, dipper nose and bucket tipping link. This also provides smooth and accurate operation.
The hydraulic hoses (including the auxiliary) are routed through the boom and dipper for ultimate damage protection.
Our latest low-wear steel bushes are highly durable and also reduce wear on pivot pins.
Productivity and Control
On the 8029 CTS, there are Nachi auto kickdown motors for smoother operation when spin turning and dozing. Tracking speed and single speed tractive effort are therefore class-leading, at 3mph (5kph) (11% improved over the 8025) and 5624lb (25.02kN) respectively.
For lifting power to match, we’ve fitted a Maxi-lift dozer ram to this JCB mini digger. You can actually lift the front of the machine on the dozer even at engine tickover, at maximum reach with a 1697lb (770kg) load. This is unique to our machine.
The 8029 CTS compact excavator also features our new EV31 hydraulic valve block, which gives 4 major benefits. Longer spools mean smoother controllability; load hold capability is increased; multifunctioning can be carried out while straight line tracking; and there’s full control isolation over all hydraulic services.
To save fuel, the 8029 CTS uses a lower power version of the 8025’s engine (torque is equal) but, because of our other innovations, productivity is still class-leading. That represents a 8% efficiency gain.
Unusually for a mini excavator, there’s plenty of room in the 8029 CTS’ cab.
Access is easy via a wide door, and the door itself latches back within the tailswing so you can work with it open. To make access to this JCB mini digger even easier, the left control pod hinges up and there’s no left foot pedal to get in the way.
There’s more leg room, a further 1.9 in (50mm) of seat adjustment and improved cab storage over the 8025. Not only that but new rubber cab mounts reduce vibration, and internal noise is just 77 dBa.
The seating position is fully adjustable for maximum comfort and there’s an efficient heating system. You can effortlessly store the gas-strut-assisted upper front screen overhead, and the lower front screen can also be removed. Plus, the whole cab structure is isolated from the slew frame for minimum vibration.
In all, the JCB 8029 CTS compact excavator is a comfortable favorite.
