New Caterpillar Waste Handler Designed for Confined Spaces

03 May 2012 Caterpillar has launched a new wheel excavator for the waste and recycling industry designed specifically for use in work areas with limited space - the M318D MH Waste Handler. The manufacturer said that the new configuration - which meets with accepted industry criteria to ensure safe operation and high production when working in close quarters - incorporates significant undercarriage and boom modifications, while retaining the proven features of its conventional M318D MH. The machine features a C6.6 ACERT engine that meets EU Stage IIIB emission standards, as well as load-sensing hydraulics, dedicated swing pump, heavy-duty axles, stabiliser configurations and a spacious cab with optional joystick steering. Caterpillar added that the new Waste Handler features a purpose-built undercarriage that preserves the rugged strength of the conventional M318D MH undercarriage, but adapts the structure to the machine's specialised application. The heavy-duty swing-bearing tower is now centred on the undercarriage, placing it equidistant from axles and stabilisers, which the company said aids symmetry and optimises balance, whether working over the front or rear. In addition, the tower is larger to accommodate the hydraulic cab-riser swing bearing. According to Cat, the boom for the new machine also has been significantly modified to fit the machine to its tasks. The new boom has a shorter pin-to-pin length of 5.35 meters (17.55 ft.), compared with the conventional M318D MH's dimension of 6.4 meters (21.00 ft.). This compact material-handling boom, designed for use with the 4200 millimeter (13.80-ft.) stick, features a welded, box-section design with thick, multi-plate fabrications in high stress areas for superior durability. The company said that these modifications ensure that the new machine meets all dimensional requirements and allows the new configuration to maintain a competitive edge in reach, height and lifting capacity, providing the highest raised-cab position. The M318D MH Waste Handler also delivers more working power than its competitors, having a net engine-power rating of 124 kW (168 PS), main hydraulic pressure (implement circuit) of 350 bar (5,076 psi), and a rated hydraulic flow of 290 L/min (77gpm). Waste options In addition to features that allow the Waste Handler to work in confined areas, the company said that an optional Waste Handling package specifically equips the machine to work efficiently in waste transfer stations or other extremely dusty applications. The Waste Handling option features an automatic, hydraulically driven fan that cleans debris from the radiator by periodically reversing airflow after a specified interval (from 2 to 60 minutes, set manually at the monitor). A dense wire-mesh hood complements the automatic fan by facilitating optimum cooling and reducing radiator clogging. For added engine protection, the company said that a Sy-Klone brand pre-cleaner separates and ejects debris from engine intake air before the air reaches the machine's primary air cleaner. Furthermore the machine's C6.6 engine is electronically controlled to maintain consistent net power in all operating situations, which the company said optimises efficiency and reduces running costs. Cat claimed that added fuel savings result from the reversible cooling fan, which is also an electronically controlled, on-demand type that automatically adjusts its speed based on coolant and hydraulic-oil temperature. For increased durability, the cab uses heavy steel tubing around its exterior bottom perimeter for resistance to fatigue and vibration. The company said that this design also allows a falling-objects guard to be bolted directly to the frame, but the guard can be raised easily for convenient windshield cleaning. A rearview camera is standard and displays images on the in-cab monitor. The manufacturer added that as with all of its Wheeled Material Handlers, the M318D MH Waste Handler can be equipped with a quick coupler and a range of specialised work tools.

But there are disadvantages too - not least of which is the fact that most are primarily designed for construction, or agricultural applications. But as Malcolm Bates explains, JCB has achieved a modest 'first' - the new 'Wastemaster' telehandler was launched ahead of construction or agricultural market versions. New K-Series Wheeled Loader Range Launched Caterpillar Corporation chose the south of France as the location to host the first in a series of 'Waste Days' aimed at enabling busy customers - or more importantly, 'prospective customers' - to see the latest Waste Handler models 'In the Iron'.
