Whether deployed in primary or secondary materials loading tasks, Caterpillar’s new Cat 986H large wheel loader delivers with low cost per tonne production in varied sectors ranging from opencast mining, underground loading, to granite block handling, steel mill applications, and quarrying.
The first Cat 986H models rolled out of Caterpillar’s Tongzhou factory in China from the fourth quarter of 2013andarenowavailable in the Southern African market.
“The development of the Cat 986H comes in response to global customer demand for a purpose-built machine that fills the gap between the Cat 980H and Cat 988H, with a major emphasis on simplified and safe operation, ease of maintenance and improved bottom line operating margins, key considerations in today’s mining environment, especially when it comes to diesel fuel consumption,” explains Barloworld Equipment group product application specialist, Brandon Stonefield. (Barloworld Equipment is the Cat dealer for Southern Africa.)
In the field, the Cat 986H has a rated payload of 10 tonnes in standard lift and 9,5 tonnes in high lift specification when equipped with a rock bucket, with a breakout force of 328kN. In turn, the general purpose bucket (standard lift) has a 12 tonnes rated capacity, and 10 tonnes in high lift. (By definition, rated payload is the material weight in the bucket that the loader is designed to carry, excluding the weight of the bucket itself, GET and wear material.) Equipped with standard lift configuration, the Cat 986H is a four pass match for the Cat 740B articulated truck andCat770Goff-highway derivative (the approximate payload in both instances being around 39 tonnes.)
In turn, and equipped with a high lift linkage, the Cat 986H will load a Cat772G(47,7tonnes) and 773G (56 tonnes) rigid truck in five and six passes, respectively. At the heart of the Cat 986His its six cylinder turbocharged Cat C15engine, generating an output(ISO9249) of305kW.Thisisoneof the most fuel efficient engines in its class, underscored by competitive tests conducted by Caterpillar. During a recent controlled truck loading study, for example, the Cat 986H burned between 30 and 35 litres per hour, in the process loading around 650 tonnes during system production.
