The flexible stainless steel bands and crawler are light enough in weight that one person can complete installation.

Bands are sized in two inch (50 mm) increments from 6 to 60 inches (152.4 – 1,524 mm). Special bands for odd sizes and extra large pipe can be made on request. Bands for 6 inch to 12 inch (152 – 305 mm) pipes are made from 14-gauge stainless steel and bands for pipe 14 inch (356 mm) and larger are made of 12-gauge stainless steel. Bands for pipe sizes 18 inch (457 mm) and larger have band stiffeners that assist in centring the band on the pipe wall.

There are no tedious adjustments when installing the band – the band latch provides quick and easy locking and release for easy positioning anywhere on the pipe. The band provides a track for the crawler to precisely follow the pipe wall arc keeping the torch at a pre-set distance off the pipe.

One band crawler fits all band sizes regardless of the pipe diameter. The crawler is quickly and easily adjusted to the band radius by rotating the crawler legs, and the grooved wheels of the crawler attach to both edges of the band. The band crawler is used in conjunction with a 1 3/8 inch (35 mm) diameter oxy-fuel torch and torch angle head adaptor to produce a precise cut and bevel. An eccentric torch holder is used to vary the torch tip to pipe height. The crawler is available with 2.7m or 4.3 m flexible drive cable and 115 vac motorising kit.

The right angle drive adaptor permits the 2.7 m or 4.3 m flexible drive cable to pivot 180° on the crawler lowering the overall profile of the crawler on the pipe to 6 inches (153 mm) in tight areas. This feature facilitates the operation of the manual band crawler from either the front or back of the crawler or from above or below the pipe.

The rack adjustable torch arm permits the cut to be started away from the cut line and moved to the cut line to reduce notching of the cut bevel. This feature fits into the eccentric in place of the oxy-fuel torch and permits the adaptation of a 13/8 inch (35 mm) plasma torch to the band crawler. It also allows the use of an oxy/fuel torch without the torch angle head adaptor.

Bands and band crawler are most commonly used on vertical pipe, larger diameter pipe, out of round pipe and when there is very little clearance. Pipeline contractors around the world use the bands and band crawler for large diameter pipe due to the ease and speed of setup and cut.
