JCB shows Stage Tier 4-compliant skid steers
JCB has introduced its first Tier 4 compact tracked loader
A Tier 4 Final-compliant tracked loader has been unveiled by JCB at Bauma 2013.
The 225T machine is powered by JCB’s Ecomax engine that uses up to 9% less fuel than the previous Dieselmax version, which was, itself, said to be up to 16% more efficient than some competitor machines.
In addition to the new engine, the large platform models in JCB’s 17-strong skid steer/compact loader range also get electro-hydraulic controls as used on small platform machines. This allows companies to specify H-pattern controls rather than the standard ISO pattern and provides the operator with three levels of response from slow (for fine trimming work) to faster and more responsive controls for digging and loading work.
Both the latest skid steers and compact track loaders are equipped with a scavenging pre-cleaner, which extends air filter service life up to 500 hours (depending on application). A reversing cooling fan is an option for machines working in particularly dusty environments.
Other options include an electric quick-hitch for faster attachment/bucket changes (JCB offers 31 attachments) and the system also reduces the chance of hydraulic oil leakage during change-over.
The company’s single loader arm design allows for a cab door on the left of the machine, meaning the operator does not have to climb over the bucket/attachment. It also says its skid steer cab is 33% larger than competitive models (46% larger on small platform models) and offers better service access.
Larger models (300 and 320 skid steers and the 300T and 320T compact track loaders) are equipped with an on-demand, pressure compensated, variable flow hydraulic pumps.
