Features and benefits
Small tail swing
The narrow swing area is well suited for operation in confined areas with only a 325 mm protrusion over the tracks.
Against wall
PC88MR-10 can work in confined spaces with its swing boom design
Large vertical pin and steel bushing
A large vertical pin and steel bushing are used at the boom foot for improved durability. An abrasion-resistant steel bushing further improves service life.

Tier 4 engine KDPF regeneration
As the technology of diesel engines has progressed from Tier 3 to Tier 4 Final, design aspects of the engines have been fine-tuned to comply with regulations to cover regulated diesel engine exhaust pollutants.
The result is that these new diesel engines are cleaner than ever before, and in many cases more fuel efficient too. Along with this comes the need to properly manage and maintain these new generation of machines to make sure that operating costs are minimised.
