build-ups, reclaim lost material and restore design capacity and fl ow rates. In most cases Martin Silo Solutions eliminate the need for confi ned space entry and hazardous cleaning techniques such as explosives, water and air lancing, typically allowing the material to be recaptured and returned to the process stream. Technicians from Martin Engineering use remote-controlled equipment from the top of the vessel to safely address blockages. With nearly 70 years of experience in solving material fl ow problems, the company employs highly-trained specialists who are safety-certifi ed to current OSHA and MSHA standards.

Most cleaning projects are performed with the Martin Heavy Duty Whip, a portable, remote controlled tool that can be lowered into storage vessels through a manhole opening. Powered by compressed air, the Heavy Duty Whip can be equipped with a variety of fl ails and cutting edges to knock down accumulated material without damaging storage vessels. Abrasion- resistant steel chain is best suited for most

applications, with non-sparking brass chain for combustible materials. Urethane fl ails can also be employed to protect lined vessels that could be susceptible to damage from metal tools. “With this technology, the need for confi ned space entry is greatly reduced”, observed Martin Engineering silo sales specialist Marty Yepsen. “The equipment can be set up quickly outside the vessel, and it’s portable enough to move easily around various bin sizes and shapes.” The Martin HD Whip uses a modular boom arrangement that extends from 2 metres (7 feet) up to 8.5 metres (28 feet) and can clean vessels up to 18 metres (60 feet) in diameter and 68.5 metres (225 feet) tall from a single central opening of just 450 mm (18 inches). The pneumatic cutting head delivers powerful whip action from the rotating head to remove buildup from walls. The hose reel easily separates from the boom assembly for transportation and set-up in tight spaces.
“There are competing systems that utilise hydraulics, but they tend to be heavy and cumbersome,” said Martin Engineering territory manager Jim Densberger. “And they present the possibility of a fl uid leak, which could contaminate otherwise-

salvageable material. The whip requires no hydraulics; it needs just 90 PSI and 100 CFM, which can usually be supplied from a plant’s existing air system.”
