The Charles Machine Works Inc.; 800/654-6481; The TPS800 series of total stations is for a variety of surveying and construction applications. The new models are easy to learn and optimized for field usage, the maker says. The TPS800 products come in three levels of accuracy–2 in., 3 in. or 5 in., and feature a minimum reading of 1 in. They offer ease of use, fast start-up routines, a large high-resolution display and alphanumeric keypad with mobile-telephone-style data entry. The TPS series is also equipped with an easy-to-use function that permits shots to a hidden point pole to measure inaccessible points. Two new wheeled excavators, the 180C W and 210C W, are designed to deliver the same reliability and powerful response of the C-Series crawler variety, but in a nimble wheeled design. One work mode allows the operator to work in a variety of applications, from trenching to fine grading, without having to change modes. The machines are also equipped with the Deere Machine Information Center, a data logger that records all machine information. The LM80 Layout Manager is designed for use with servo and robotic total stations. It gives concrete and general construction contractors the ability to carry, manage, work with and lay out jobsite blueprints right in the field, says the maker. Contractors can use the LM80 for layout of control lines, offset points, excavation lines, foundations, forms and footers, and anchor bolt placement. The new Ditch Witch subsite 300SR/ST is an electronic locating system designed to locate buried telephone, power, gas and other utility lines. It weighs only 5 lb and features a moisture-resistant construction that allows it to perform in a variety of jobsite conditions. The system includes a 300SR receiver and a 300ST transmitter. Both components operate up to 40 hours and 150 hours, respectively, on six C-cell batteries.
