OWATONNA, Minn. – The SG7 SURFACEPRO™ edge grinder from General Equipment Company is a compact, versatile solution for targeted concrete removal in smaller areas. Lightweight and highly maneuverable, it provides the rigidity to remove material with more accuracy and control than larger machines, while features such as a self-adjusting skirt height, an upright ergonomic design and a flip-up shroud edge help operators work faster, cleaner and closer to walls.
Leading the SG7’s features is its self-adjusting skirt height, which is built into the dust shroud. The exclusive molded rubber housing of the shroud combined with replaceable nylon wear strips on the bottom edge allows it to float over the floor, rising and lowering to match the exact height of the grinding surface and the wear level of the grinding cup wheel. This maintains a constant, tight seal against the concrete, compensating as the grinding segments wear down or as the machine moves over peaks and valleys in the concrete. The result is better efficiency and a healthier job environment as operators no longer need to stop, bend and stoop to reset the shroud, and the majority of the dust is trapped at the source instead of spreading through the work area.
The heavy-gauge steel frame is ergonomically designed to allow the operator to work in a fully upright position. This greatly reduces the potential for lower back pain, strained knees or other occupational-related health issues, all while increasing productivity over hand-held grinders. The SG7 is also easy to take from job to job. With a detachable handle and weighing only 39 pounds (17.7 kg) without a blade, it is easy to lift and transport, fitting in almost any size vehicle and moving easily from one area of a facility to the next.
The SG7’s flexible dust shroud also incorporates a flip-up edge. This allows the operator to get a clear view of the front edge of the grinding cup wheel when working near walls and other obstacles.
“The SG7 is not a conventional grinder one would use to grind a floor flat and level,” said Dennis Von Ruden, president of General Equipment Company. “It’s best used to remove concrete for specific applications, such as feather leveling cracks where minimal concrete removal is desired, eliminating trip-and-fall hazards from door entrances, clearing away small areas of adhesive from concrete surfaces and profiling concrete floor areas around drains to better direct water flow.”
“What we’re finding is large retailers, warehouses and related operations are renting or buying the SG7 to act as a Swiss Army knife of sorts for smaller concrete maintenance jobs that commonly pop up from time to time,” Von Ruden added. “Instead of scheduling a contractor with a full-size machine, a maintenance crew can use the SG7 to take care of problems quickly as they arise.”
Other standard features include Anti-Vibe™ caster wheels, a 2-inch (50.8 mm) diameter dust connection port and hose to handle applications with dust control requirements, and a 7-inch (178 mm) diameter diamond grinding cup wheel.
In business since 1955, General Equipment Company is a family-owned manufacturer of hole digging, surface preparation, dust collection, plus portable ventilation and air scrubbing equipment.
