Crawler wheels from Cua Claws can help improve footage in wet slippery PVC or another plastic pipe. The wheels have tungsten carbide furnace brazed to the wheel. An extended range of modes is available that can be retrofitted to the customer’s crawler. The company also offers a service to apply its carbide to crawler wheels. Some wheels are stainless and cannot be processed so Cua Claws has a line of replacement wheels of exact fit in mild steel so the grit can be applied. This way the customer can harvest the savings to re-grit instead of replacing the wheels when necessary. 714-697-8697; www.cuaclaws.com.
