With manufacturers keen to meet new regulations and deliver greater performance to customers, an array of new soil compactors are now coming to market.
One of the new developments from the
Customers can select two optional ACE packages, which are said to help optimise performance. These systems can provide accurate measurement and documentation, precisely measuring and evaluating material stiffness. The ACEpro continuously adjusts frequency and amplitude depending on compaction measurements, as well as eliminating drum bouncing and minimising the risk of over-compaction. Meanwhile the ACEforce system shows compaction progress and includes ADS documentation software, with an office analysing feature. The firm claims that this package allows customers to use smaller, more efficient machines to deliver compaction force typically associated with larger units.
In use, the display provides the most relevant information and shows the optimal rolling speed. The unit displays compaction data which can be printed if required, while the package also helps ensure a homogenous compacted area and can highlight trouble spots early in the process
The technology can be used with machine control technology from all the major suppliers to provide mapping and operator guidance. The machine is also equipped with Ammann’s vibratory system, which offers different amplitude settings and is designed for efficiency, by driving compaction forces into the material and away from the operator
Weighing in at 11.6tonnes, the machine has a 2.13m-wide drum while other benefits include a high visibility seating position, ergonomic controls and easy access for maintenance.
Key features are the compaction measurement systems, the compaction meter value (CMV) or the firm’s sophisticated machine drive power (MDP) unit, with smooth drum variants being offered with both. The CMV package is accelerometer-based, while the sophisticated MDP indicates soil stiffness by measuring rolling resistance.
A wide range of models is offered, with both smooth drum (CS) and padfoot (CP) variants available. The machines range from the 7-20tonne classes, with the CS66B particularly popular in Europe while the CS79B is designed specifically for use in lesser regulated markets.
The smallest of the three is the SP-3 model, which weighs 17.5tonnes and can deliver a load of 81,156Nm. The mid-range unit is the SP-5, which weighs in at 22.7tonnes and delivers a load of 91,212Nm. The top of the range SP-8 weighs 33tonnes and delivers a load of and 99,877Nm. All three machines share the open-ring wheel design, which is said to allow the wheel rings to sink into the ground due to static weight. The design is said to deliver compaction from the bottom up, unlike more conventional solid padfoot drums. Customer options for the Rexpactor models include a standard semi-U blade or an optional tilt blade.
Power for the H10i comes from an 85kW diesel that offers high output, meets the latest emissions regulations and is said to offer low fuel consumption. The H10i, as well as the updated H12i and H14i class models, all feature the firm’s proven three-point articulation system, which is said to optimise traction on poor terrain by allowing the drums to stay in better contact with the ground.
All three machines benefit from Hamm’s latest telematics technology, while being offered with the choice of a version with the vibration-oscillation (VIO) compaction system. Customers can also select options including a combiscraper, dozer blade and various other additional features.
All of the H series machines come with three-point pivot articulation, to maximise drive on rough ground and feature ergonomic work stations and improved visibility. An important feature is the Easy Drive operating system, which has been designed with language-neutral controls while the compactors can be adapted to suit different operating conditions.
JCB is introducing its 116D single drum soil compactor, which is designed for customers in Africa, Asia and the Middle East. With its Tier 3 compliant 85kW JCB engine, the 11.35tonne 116D is said to offer low fuel consumption, high compaction performance and improved operator comfort.
The proven JCB DieselMax four-cylinder engine has mechanical fuel injection, and can run with lower quality fuels, offering fuel savings of up to 15% against competitive machines in field trials. The machine also uses a JCB drive axle, with a limited slip differential, to boost traction.
The soil compactor comes as standard with a canopy or an optional ROPS canopy. It also comes as standard with the JCB LiveLink telematics system which allows managers to remotely access working hours, vibration and travel data. The system also provides a tracking service for improved machine security.
Drum widths range from 1.37-2.13m and the three machines are all offered with a choice of smooth or padfoot drums, as well as with the padfoot with shell-kit variants. The SV204T weighs from 4.7-5.45tonnes, depending on specification, while it is driven by a 3.3litre
The SV204T is being imported from Japan; however for the US market, production of the SV414TF and SV544 will commence shortly at the firm's US facility in Georgia. These will be powered by Tier 4 Final compliant Cummins diesels, the QSF2.8 and QSF3.8 units respectively. The SV414TF is a 7.8tonne class machine and takes the place of the earlier SV412. The SV414TF weighs 8.4tonnes when fitted with the padfoot drum and shell kit and has a 1.7m-wide drum, while it offers a variety of frequency and amplitude combinations. There are two frequency options: 1,800vpm and 2,280vpm, while there are two amplitude options of 0.5mm and 1mm. Ground clearance is 340mm while its kerb clearance is 440mm and side clearance is 101mm. Meanwhile the SV544FB takes over from the SV540. Users of the special SV414TF model can benefit from a choice of varying drum vibration rates, with high-frequency settings as well as a choice of two amplitudes. Aimed at the 8.4tonne class, the SV414TF is also equipped with Sakai’s novel proprietary drive system.

The machine is said to be able to cope with working on gradients due to a traction system that improves gradeability and prevents the wheels or drum from spinning out. Meanwhile the design of the articulation system maximises stability and manoeuvrability on uneven terrain. Versatility is offered as the smooth drum can be switched to padfoot use by clamping on a padfoot shell. Power comes from a Tier 4 Final compliant diesel delivering 110kW and said to deliver high torque at low rpm, as well as high fuel efficiency. Passive regeneration cleans the DPF unit automatically, while the machine’s cooling system is said to be efficient and only runs when required.
Other improvements include the large cab, with good all-round view as well as the ergonomic controls. Designed to be highly durable, the machine can cope with extended operation according to the firm, meanwhile access for maintenance is also said to be good, helping reduce downtime for servicing. Diagnostics further reduce the time needed for maintenance and allow customers to better plan service intervals.
