Skid steers are arguably the most common, most popular and most highly utilized piece of equipment on a typical construction site. Along with their tracked brethren, they make up the largest percentage of construction machines sold in North America; there are over a dozen suppliers; and as of CONEXPO-CON/AGG 2011, you have even more models and brands to choose from.
Here are some of the latest entries into the skid-steer market. To obtain more information on these models, turn to the reader service card following page 20, or visit the Equipment Network at ForConstructionPros.com.
Bobcat M-Series models
Since its introduction nearly two years ago, Bobcat continues to build upon its M-Series loader line. The latest additions are the S750 skid-steer and A770 all-wheel-steer loaders, both of which boast rated operating capacities of over 3,000 lbs.
The S750 delivers 11 ft. of vertical lift — 3.5 in. higher than the S300 it replaces — and features a 23-gpm standard hydraulic flow, a boost of 11%. Its operating weight is 8,730 lbs., with a rated operating capacity (ROC) of 3,200 lbs. Power is supplied by an 85-hp turbo-diesel engine.
The 9,460-lb. A770, which replaces the A300, offers 132 in. of vertical lift height, 31.5 in. of reach and a 42° dump angle for easy truck loading. ROC is 3,325 lbs. and tipping load is 6,650 lbs. Power is provided by a 92-hp liquid-cooled Tier 3 diesel engine. The standard two-speed transmission provides a 12.3-mph travel speed in high range and 7.1 mph in low range.
All-wheel-steer (AWS) capability is designed to minimize ground disturbance, reduce tire wear and enable faster travel speed. For applications where it’s not needed, the operator can switch to skid-steer drive at the press of a switch.
In addition to the features found on all M-Series models — such as a cab-forward design and added creature comforts — the hydraulic system has been engineered for higher standard flow and pressure to give attachments more power for quicker operation. New job-enhancing features have also been added to the optional deluxe instrumentation panel. A 5-in., full-color LCD screen offers better readability and interaction, and easy-to-read virtual sweep gauges allow the operator to quickly read and understand machine performance.
Case Alpha Series and New Holland 200 Series
While initially unveiled at The Rental Show, CONEXPO-CON/AGG provided the first chance for contractors to check out the new Case Alpha Series loaders.
The series includes the SR130, SR150, SR175, SR200, SR220 and SR250 radial lift and SV185, SV250 and SV300 vertical lift models. They range from 46 to 90 hp, with ROCs from 1,300 to 3,000 lbs. and bucket breakout forces up to 8,585 lbs.
Improved visibility, operator comfort, climate management and operator controls are Alpha Series hallmarks. Cabs are 25% larger and feature an ultra-narrow wire side-screen design that improves operator visibility. The glass surface is increased to provide 360° visibility. Creature comforts have been added inside the cab, as well, to enhance operator productivity.
The new Power Stance chassis design includes a longer wheelbase combined with a 30/70 front/rear weight distribution. This keeps the center of gravity from moving when the loader arms are raised.
The L218, L220, L223, L225 and L230 are rated from 57 to 84 hp, and feature the vertical lift Super Boom design. The L218 has an operating weight of 5,850 lbs. and a bucket breakout force of 5,435 lbs. The L230 has an 8,300-lb. operating weight and a bucket breakout force of 8,585 lbs.
A self-leveling bucket feature allows attachments to maintain the preset location throughout the lift cycle. A 53° dump angle lets operators empty the bucket faster. And an optional Glide Ride feature delivers a smooth ride over rough terrain.
