Caterpillar debuts Selective Catalytic Reduction (SCR) equipped Tier 4 Final 926M, 930M and 938M wheel loaders at “World of Concrete”

Niels Tholen - 9 February 2015

Caterpillar showcased its new Tier 4 Final M-series wheel loader offering at the World of Concrete exhibition in Las Vegas, NV 3-6 February 2015. The new M-series replaces the previous K-series wheel loader offering and comes equipped with Selective Catalytic Reduction (SCR) technology, Diesel Particulate Filters (DPF) and a Cat 7.1 ACERT Tier 4 Final engine. SCR consumes diesel exhaust fluid (DEF).

Besides new technology and a new engine, three engine modes are designed to allow peak performance under diverse driving conditions. The Hystat mode enables aggressive engine braking while performing high-power requiring tasks such as lifting heavy objects. Torque Converter mode allows the machine to free wheel down hills while Ice mode is designed for low-power operations.

According to Caterpillar, the new engine, three engine modes and aftertreatment technology will result in a "hybrid-type" 5 to 10% fuel saving.
