Putzmeister Develops "Reusable" Base Plates to Free-Stand Placing Boom Towers
Putzmeister Develops "Reusable" Base Plates to Free-Stand Placing Boom TowersPutzmeister America has developed "reusable" base plates as an affordable means of freestanding a Putzmeister placing boom tower up to 50 feet (15.2 m) on a standard foundation.
Contractors can realize substantial savings as the four Putzmeister base plates are priced under $2,000. Plus, unlike other methods, they are "reusable" for future projects. The plates also accept common "off-the-shelf" threaded rods, which can be conveniently purchased from local suppliers anywhere in the country.
The base plates work with all Putzmeister placing booms from 24 to 34 meters, as all models pin connect to the same modular TG 10 tower. In addition, contractors can install the placing boom with very little site preparation, as the foundation can accommodate very low soil pressure conditions of 1,500 psf - a figure that most ground exceeds.
Each octagonal-shaped base plate weighs 216 pounds (98 kg) and easily bolts to the bottom of the tower. However, instead of the normal two-bolt connection on each leg, 10 additional 1.25-inch (32 mm) threaded rods are embedded into a concrete pad around each plate. This means that the placing boom can be conveniently installed at the project's onset compared to other techniques, which require openings in the building after three to four floors are already poured.
Since the introduction this spring, Putzmeister base plates have proven popular due to their highly versatile design and very affordable approach of freestanding up to 50 feet (15.2 m). Putzmeister standard foundation anchors or fixing angles are also available to achieve greater freestanding heights up to 80 feet (24.4 m).
