| New mini hydraulic excavator from Caterpillar  The Caterpillar 302.5C Mini Hydraulic Excavator features more power, greater digging forces, a more comfortable operator station and easier access for service than its predecessor, the 302.5. The new C-Series model features 10 percent more bucket digging force and 10 percent more stick digging force than the previous model. The new mini excavator gets more work done faster through an engine power increase of about 8 percent—to 18.6 horsepower. The engine meets US EPA Tier 2 and EU Stage II emissions standards. The 302.5C retains the variable displacement hydraulic pump, which eliminates stalling and enables the excavator to dig through the toughest conditions. Operating weight of the excavator is 2850 kg when equipped with a cab and 2745 kg with a canopy.The C-Series Mini Excavator cab is large and spacious for an expansive viewing area and good air circulation. When compared to the previous model, the uncluttered, flat floor is larger and the door is wider. For ventilation the cab has a retractable front window that can be stowed easily in the roof space with a gas strut assisted linkage. Air conditioning is available on the 302.5C. A suspension seat, console-mounted implement controls and adjustable wrist supports help reduce operator fatigue. Pilot hydraulic implement controls are low effort. Switches incorporated in the joysticks provide easy control of boom swing and auxiliary hydraulic functions. The two-speed travel system is controlled by a switch on the dozer lever, which makes speed changes easier while dozing. The dozer float function makes grading tasks easier. The machine monitoring system is mounted near the operator's line of sight to ensure that gauges and warning lights can be seen easily. The operator station includes a mobile phone holder and 12-volt power source. For lower owning and operating costs, the new machine features high strength side panels, polyurethane paint finish and a large swing-out rear door for service access. A lifting side panel provides access to the hydraulic tanks and main implement valve. The 500-hour oil and filter change interval helps keep operating costs down. The front linkage is a fabricated box section, built for performance and long life. The independent swing boom enables the machine to work next to a wall or obstruction. The 200-degree bucket rotation ensures good material retention at height as well as flat trenching capability. A choice of stick lengths and a wide range of Cat Work Tools add versatility to the 302.5C. write your comments about the article :: © 2005 Construction News :: home page |
