Pulte Homes is using Grove truck cranes to build hundreds of new homes in northern Virginia and Maryland. Five Grove TMS900E truck cranes and a Grove RT530E rough- terrain are working for the Washington Division of Pulte Homes. It expects to construct 500 houses across five counties in northern Virginia and Montgomery, Maryland, by the end of this year. The homes are spread across a six county area up to 65 km (40 mi) from the plant where Pulte Home Sciences manufactures concrete panels, floor trusses, exterior walls, and interior panels used in construction. Brian Delhagen, field operations manager with Pulte Homes Sciences, explained why he chose Grove truck cranes to build the new homes. “We chose the Grove truck crane mainly because of the cost of movement. Our jobs last only for about a year or so and during startup we moved the two cranes we had at that time quite a bit,” he said. “The decision also gave us flexibility to move to different jobs more easily. Our developments are paved streets and we rarely need to access the house from the other side of the curb.” The homes, which range in size from 185 m² (2,000 ft²) to 464.5 m² (5,000 ft²) each have different panel qualities. On average each home uses 25 to 38 concrete panels for the foundation, while the floor consists of another 10 to 13 panels. Pulte’s plant optimizes the panel weight and sizes to work with the crane capacity. Typically, 22.8 m (75 ft) to 26 m (85 ft) of radius is required to lift the panels in with the TMS900Es, depending on weights, where the house is staged and its size. Pulte rigs these cranes with 29 m (95 ft) of main boom and a counterweight that weighs 5,851 kg (12,900 lb) to handle the panels. Typical swing time using the TMS900E truck cranes is four to seven minutes per panel. Each panel measures 2.7 m (9 ft) to 11 m (36 ft) and weighs in around 1,814 kg (4,000 lb). An entire foundation can be set within eight to ten hours with a crew, including a crane operator, of seven workers. Pulte’s RT530E, a 4x4 rough-terrain crane which has a 27 t (30 USt) capacity rating, is rigged with a four-section 29 m (95 ft) boom. It is being used for installing exterior framing panels and roof trusses. In addition, the crane is harnessed as a general work horse and used for all manner of different lifting duties within its capabilities. “We went with the Grove brand because it is the industry leader of hydraulic cranes,” said Delhagen. Grove has the only 80 t (90 USt) crane that could handle the weights of our precast walls at the radius we need. Grove has also been very willing to build machines that meet our specific needs. For example, while we do not need a second hoist, the machines have been built to accept one should we choose to add it later. That’s service.” About the Manitowoc CompanyThe Manitowoc Company, Inc. is one of the world’s largest providers of lifting equipment for the global construction industry, including lattice-boom cranes, tower cranes, mobile telescopic cranes, and boom trucks.
