2.0 - GENERAL
The Mathey Dearman Band Crawler is engineered and designed to hold and rotate a 12” long 1-3/8” / 35mm
diameter oxy/fuel or plasma machine torch around 6” - 60” / 152 – 1524mm pipe to cut or to bevel pipe ends
producing a bevel for the welding two (2) pipes together. The Band Crawler, both manual and motorized, fits
all band sizes. Stainless Steel Bands are available with a standard latch for standard API line pipe sizes 6” to
60” / 152mm to 1520mm in 2” / 50mm increments. Special Stainless Steel Bands for odd size or larger pipes
available on request.
Mathey Dearman Band Crawler consists of two (2) main assemblies:
1. The Flexible Stainless Steel Band installs around the outside diameter of the pipe to be cut or beveled. The
Stainless Steel Band forms to the pipe outside diameter even under the most sever out-of-round conditions and
acts as a guide to insure consistent cut or bevel.
2. The Band Crawler, which attaches the flexible Stainless Band, moves around the pipe by means of a 9’ or 14’
Flexible Drive Cable. A 230vac Motorized Band Crawler is also available to rotate plasma or oxy/fuel torch
around the pipe.
