Levelling sets handle heavy machines

The GN350 series are ideal for permanent levelling of machine tools, production line machinery, process equipment or gravity transport systems where very accurate degrees of slope may be required.

Accurate levelling of equipment and heavy machinery is facilitated by a new range of levelling sets from Elesa.

With individual load ratings from 4000 to 49,500kg static load, the GN350 series are ideal for permanent levelling of machine tools, production line machinery, process equipment or gravity transport systems where very accurate degrees of slope may be required.

Normally used in a configuration of three or more per equipment piece, the static load capacity created is sufficient to deal with even very large machinery.

The GN350 levelling sets are available in sizes from 25 to 80mm diameter, and are generally used in conjunction with spherical levelling washers, which take up angular differences in ground or equipment faces to ensure stress free positioning.

Each GN350 set comprises a threaded upper sleeve with a fine thread, which allows a stepless and precise setting and locking using a standard C spanner.

Normally, this screw is permanently and securely locked by the static load generated when the mounting screw is tightened - however if this is not considered sufficient then suitable locknuts are available.

Armory getting concrete parking for heavy machinery

Heavy machinery such as construction equipment and tanks are coming to the Keokuk National Guard Armory when a $323,000 project is completed around Labor Day.

A 70-by-85-foot section of the parking area behind the armory is getting an eight-inch concrete surface to handle the heavy machinery, according to Curtis Grant, project manager for First Construction Group, Inc. of Burlington, the general contractor. Another 100-by-40-foot portion of the parking lot will have a rock surface.

In addition, a 30-foot-long, 28-foot-wide concrete ramp is being built to load and unload the heavy machinery, Grant said.

The machinery is stored now at the National Guard Armory in Mount Pleasant, which also is scheduled to get a parking lot upgrade. No bids have been let yet on the Mount Pleasant project. Once the Keokuk armory project is finished, the National Guard will be able to store heavy machinery at each location, Grant pointed out.

A trench drain also is being installed near the metal maintenance vehicle storage building behind the Keokuk armory to handle water coming off the building’s roof and the improved parking lot.

Five trees were removed during the work in Keokuk, and they will be replaced with five new blue spruce trees or some other variety, Grant said.
The Keokuk armory’s parking lot will be enclosed with fencing with barbed wire on top for greater security. Light poles also will be installed.

First Construction Group, Inc. was the general contractor for the construction of the nearby Keokuk Aquatic Center.
