To some, the concept would seem obvious. Just credit Case Construction Equipment with being the first one to use it.
The company's new 521D wheel loader features a mid-mount cube-shaped cooling system that, by eliminating stacked coolers, prevents debris from plugging between coolers and provides fresh air to all coolers. The cooling system's design allows the engine to be placed behind the rear axle, shifting the weight of the machine and providing improved stability.
The 521D is a new entry in the company's line of wheel loaders. Powered by a 110-horsepower turbocharged diesel engine, it offers 20,951 pounds of breakout force and has a lift capacity of 23,634 pounds. It is available in standard Z-bar and tool-carrier configurations ideal for a variety of material handling, construction, forestry and agricultural applications.
The unit's closed-center, load-sensing hydraulic system adjusts automatically and provides optimum flow and power to all hydraulic functions while the wide-angle flow-amplified steering offers smooth steering at all engine speeds.
Another big advantage of the 521D is its ease of maintainability. All maintenance points are at ground level allowing a technician to easily service the machine. The remote drains for engine oil, hydraulic oil and engine coolant are all grouped in one location and the machine's flip-up hood provides easy access for all engine parts.
