Spectra DM-20 Bulldozer Bolt-On Mount | 42-Inch Pole | LR Series Compatible
The Spectra DM-20 Bulldozer Bolt-On Mount is a robust structural accessory engineered for the seamless integration of Spectra Precision LR series laser receivers onto heavy machinery. With a fixed pole height of 42 inches, this mount provides the necessary elevation to ensure an unobstructed line of sight between the laser transmitter and the machine receiver, maximizing detection range and leveling precision.
What laser receivers are compatible with the Spectra DM-20?
This mount is specifically engineered for full compatibility with the Spectra Precision LR20, LR30, LR50, and LR60 laser receivers. The 6.5-inch hole pattern ensures a secure and standardized mechanical interface for these specific models.
How does the 42-inch pole height benefit leveling operations?
The 42-inch pole height offers an optimal vertical offset that clears machine components, allowing for a wider detection range of the laser beam. This elevation is critical for maintaining high accuracy in grading and leveling across diverse construction environments.
What are the primary mounting specifications for the DM-20?
The DM-20 utilizes a bolt-on design for simplified installation on bulldozer blades or chassis. It features a standardized 6.5-inch hole pattern and a durable construction designed to withstand the high-vibration and demanding conditions typical of infrastructure and surveying projects.
