JCB Hydradig Wastemaster breaks new ground

Written by: Editorial staff | Published:

Making its first appearance in Europe, the JCB Hydradig Wastemaster is reported to be a totally new material handling solution and is said to bring new levels of innovation and engineering excellence to the growing compact wheeled machine sector of the waste and recycling market.

According to JCB, the Hydradig Wastemaster is a ground-breaking digging, lifting, loading and tool-carrying machine for waste, recycling and municipal operations. The machine is said to deliver firsts on five important customer criteria to ensure maximised productivity and safety in waste and recycling operations:

  • Visibility – an operator view around the machine
  • Stability - a low centre of gravity to allow stable lifting while working at full reach
  • Mobility – up to 40km/h between job sites (20km/h with solid and semi-solid tyres)
  • Manoeuvrability – two and four wheel steer and crab steering delivers maximum usability on the smallest of job sites
  • Serviceability - ground level access to all maintenance points

Wastemaster specification

David Banks, JCB sales manager for waste & recycling, said: “With safety of paramount importance, the Wastemaster features a cab guard falling object protection system (FOPS). This fully protects operators while they enjoy the benefits afforded by the cab’s exceptional all round visibility. From ground level, the JCB Hydradig’s all-round visibility also allows ground staff to see the operator at all times. In addition the JCB Hydradig’s white noise reversing alarm and red and white chevrons improves site safety over conventional excavators.

“To maximise vehicle uptime, the JCB Hydradig Wastemaster has semi-solid tyres that eliminate the risk of punctures and an exhaust heat shield to protect the machine. Light guards are also fitted to ensure the Hydradig Wastemaster’s lights are in full working order for operation on site and when travelling between sites on the road. Climate control also contributes to the productivity advantage by allowing the driver to work in a comfortable environment.”

JCB Hydradig Wastemaster performance

The JCB Hydradig Wastemaster is reported to offer a sturdy all-wheel drive, four-wheel steer chassis, based on JCB’s loadall telescopic handler concept. This delivers three-mode steering for maximum manoeuvrability and stability when travelling at speed. Power comes from JCB’s Tier 4 Final diesel engines, delivering 81kW (108hp) and industry-leading levels of low rpm torque. The engine achieves the Tier 4 Final emission levels without an expensive diesel particulate filter (DPF), reducing cost and complexity for the customer.

The engine is side-mounted, which is said to place the centre of gravity far lower than conventional 10-tonne excavators, adding to the machine’s stability. Hydrostatic drive is provided through a combination of a variable piston pump and a variable piston drive motor, to a central transfer box and then to both axles. This driveline layout offers a step-less 0-20km/h speed range for solid or semi-solid tyres and a 40km/h option for conventional pneumatic tyres.

"Near 50-50 weight distribution between the axles and a longer wheelbase than competitive 10-tonne machines delivers improved stability, increasing confidence for the operator. A 2,650mm wheelbase provides a superior ride with secure handling. The lack of forward and back ‘nodding’ when driving means that the JCB Hydradig Wastemaster operators can maintain higher travel speeds between job sites, improving productivity, with JCB’s SRS boom suspension system available as an option to further improve ride comfort," added Banks.

"The machine is equipped with three steering modes as standard: two-wheel steering for security at road speeds and four-wheel and crab steering, providing maximum manoeuvrability on site. A front axle with +/- 8° of oscillation delivers excellent rough terrain traction and stability."

An optional reverse steering function is reported to allow the operator to always have conventional steering direction, negating the need to counter steer when facing the rear of the chassis.

The JCB Hydradig Wastemaster offers a minimum turning radius of just under 4 metres at 3,946mm on single tyres, and operating within four wheel steer.

The machine can be ordered with single tyres, extra-wide flotation tyres or twin tyres on each axle. Customers can also choose between any combination of dozer blades and stabiliser legs at either end of the machine, providing a modular design that can be tailored to an individual operation. Both parallel lift and radial lift dozers are available.

According to JCB, with the engine, driveline, hydraulic and diesel tanks mounted on the lower chassis, the upper structure has a reduced tailswing of 120mm, 29% less than any competitive machine, allowing the machine to work on the most confined waste and recycling centre. The lower centre of gravity is also said to make the JCB Hydradig Wastemaster incredibly stable when working with selecting and materials handling rabs at full reach, particularly over the tyres, even without stabilisers of dozer blade. The reduced tailswing means the JCB Hydradig Wastemaster reportedly can lift more than competitive conventional tailswing machines.

Bosch Rexroth electro-hydraulic controls allow the main valve block to be mounted beneath the side canopy and directly above the slew ring, so there is no hydraulic noise inside the cab. The closed loop hydrostatic transmission, with separate pumps for traction drive and boom power, is said to make it easy to multi-function the dig-end.

Customers can choose between a monoboom or a triple-articulating TAB boom, with three dipper lengths of 1,650mm, 2,000mm and 2,250mm to suit a range of applications. Over the side stability, when running tyres alone, is claimed to be 3% better than any competitive machine. All dig-end pins are equipped with impregnated bushes, allowing 500-hour greasing intervals. The dipper nose geometry matches that of JCB’s 3CX backhoe loaders and the firm’s larger midi excavator models, permitting the use of a host of buckets and powered attachments.

The JCB Hydradig Wastemaster can be used with a variety of tilt-rotator models and can be equipped with mechanical and hydraulic quickhitches from the factory. A high flow auxiliary circuit is standard and the machine can be equipped with two low flow circuits, plus dedicated hydraulic circuits for quickhitch operation. Fully guarded hose burst check valves are available on the boom, dipper and bucket rams, for optimum lifting safety.

A hand-held tool circuit is available as an option, allowing operatives to work with a range of powered hand tools, including breakers, road saws and pumps, utilising the hydraulic power from the Hydradig.

"The JCB Hydradig Wastemaster is an extremely versatile tool carrier and can be used with a range of around 50 JCB attachments – making it an ideal choice for a vast array of applications," stated Banks.

Cab with a view

According to JCB, the Hydradig Wastemaster’s ROPS certified cab and FOPS certified guard has been purpose designed and built for the machine. Constructed using the Command Plus design DNA first seen on the company’s larger wheeled loading shovels, the Hydradig cab has a huge amount of internal space. All-round 360° visibility is said to be "exceptional, delivering a real first for operators in terms of waste and recycling site safety and ease of use". The operator is said to be able to see within 1m of the machine’s footprint at ground level from within the cab.

With the engine mounted in the lower chassis, and no hydraulic operation within the cab, the internal noise level is an automotive 69dB(A), thereby said to reduce operator fatigue and make the Hydradig "an incredibly relaxing place to spend the day". A choice of mechanical suspension seat and optional heated air suspension seats are said to further improve the operator environment, while independent arm rests make it easy for all operators to find a comfortable driving position.

The machine benefits from JCB’s latest in-cab 7” full colour monitor, managed through a rotary controller. This configurable system allows the operator to set working modes and auxiliary hydraulic flows and pressures for both JCB attachments and other makes of work tool. Operators and managers can also programme engine auto idle timing, from 2-30 seconds, to maximise fuel efficiency.

All daily service checks and regular maintenance can be carried out from ground level, with a lift-up engine canopy providing access to the engine and filters.

"The JCB Hydradig Wastemaster offers the best SAE service rating in its class (33% better than its closest competitor) and there is no requirement for operators to climb on the upper structure for regular maintenance," said Banks. "The JCB Hydradig Wastemaster will be supplied as standard with a five-year LiveLink telematics contract, delivering improved uptime and allowing fleet managers to maximise utilitsation of the machine. LiveLink also delivers improved security, with the opportunity to geofence operation and to pair the machine’s ECU with the LiveLink system to prevent unauthorised engine starting."
