The Melroe brothers, of Melroe Manufacturing Company in Gwinner, North Dakota, purchased the rights to the Keller loader in 1958 and hired the Kellers to continue refining their invention. As a result of this partnership, the M-200 Melroe self-propelled loader was introduced at the end of 1958. It featured two independent front-drive wheels and a rear caster wheel, a 12.9 hp (9.6 kW) engine and a 750-pound (340 kg) lift capacity. Two years later they replaced the caster wheel with a rear axle and introduced the M-400, the first four-wheel, true skid-steer loader. The M-440 was powered by a 15.5 hp (11.6 kW) engine and had an 1,100-pound (500 kg) rated operating capacity. Skid-steer development continued into the mid-1960s with the M600 loader.
"Knowing the specific applications the customer would like to perform will help a rental business determine the size and power of machine needed to most efficiently complete the tasks," says Rostberg. "Asking questions and getting to the core of the customer's work will help determine this. Also, while inquiring about the customer's needs, a rental business might discover opportunities to rent attachments that will help the customer more quickly and efficiently complete their job."
Jobsite dimensions are one of the greatest factors to know to fit the skid steer to the job. "Understanding physical limitations of the work area often dictates the class that may be used in the application," says Dennis Turney, Hyundai Construction Equipment. "The next consideration would be the lifting height or dumping height requirement, along with the capacity of the job. Finally, hydraulic capacity needs to known in order to operate any hydraulic attachments.
The new Cat 272D skid steer and 299D compact track loader are joined by high-performance counterparts, the 272D XHP and 299D XHP, which are the largest, most powerful skid steer and compact track loaders Caterpillar has built. The electronically controlled Cat C3.8 engine, which meets EPA Tier 4 Interim and European Stage IIIB emissions standards, is equipped with the Cat NOx Reduction System.
Our four highly versatile skid steers, ranging from 68.4 to 70.7 hp, are up to whatever daunting challenge you throw at them. Each is built around one of YANMAR’s powerful, fuel-efficient Final Tier 4 diesel engines, so they won’t back down from even the toughest job. With rated operating capacities from 1,650 to 2,700 pounds, and two easy-to-operate QuickAttach™ mounting systems, these machines are also rugged enough to handle just about any attachment you need. Couple that with spacious, high-visibility operator’s areas – built for comfort and safety – and you can work a long day without feeling like you did.
This machine size's ROC allows it to lift the heaviest loads, such as moving pallets of brick or dumping loads of dirt into the back of trucks. "These machines also have the horsepower and hydraulic flow to tackle tough jobs and attachments," says Rostberg. "Attachments that perform best with a high-flow machine, such as a wheel saw or planer for road construction or a forestry cutter for site preparation, work best with these machines."
Some models of skid steer now also have an automatic attachment changer mechanism. This allows a driver to change between a variety of terrain handling, shaping, and leveling tools without having to leave the machine, by using a hydraulic control mechanism to latch onto the attachments. Hydraulic supply lines to powered attachments may be routed so that the couplings are located near the cab, and the driver does not need to leave the machine to connect or disconnect those supply lines.
