Working in waste and recycling facilities may be one of the more heavy-duty jobs for the purpose-built wheel loaders that we call waste handlers. These robust machines are outfitted with a number of features and performance enhancers suited specifically for work in these applications. An extensive availability of attachments from forks and grapples to buckets with rubber cutting edges make these machines extremely versatile. The right machine for each application will depend greatly on the available operating space, the type of material being handled and the operational demands put on the machine. In this article we’ll examine key factors to consider when evaluating waste handlers and new technologies that may help your operation run more efficiently.
Understanding your Tier 4 engine options
The buzz of equipment manufacturers talking about Tier 4 engine requirements is growing to a deafening climax, but there are important things you need to know when considering waste handlers. There are two primary solutions available in this equipment category: Selective Catalytic Reduction (SCR) and Cooled Exhaust Gas Recirculation (CEGR). SCR is an after-treatment system that creates a chemical reaction by adding diesel exhaust fluid (DEF). This transforms NOx into nitrogen and water, which occur naturally in the atmosphere. CEGR operates differently: exhaust gases are cooled, blended with recirculated exhaust and returned to the cylinder, which lowers combustion temperatures and reduces NOx. Particulate matter (PM) levels are then reduced through the use of an after-treatment diesel particulate filter (DPF) system.
