Certified Crane Care How to Choose Hoists & Cranes for Offshore Applications


In the world of Bridge Cranes and Electric Hoists the configurations are highly customizable. The need for customization arises from the various conditions dictated by application and environment. Suppose your warehouse may be a refrigerated storage space and your machines must operate at freezing temperatures or your warehouse has low ceilings and your head room is limited, there are options that can help you maneuver around these obstacles. One of the most custom option intensive industries is the Oil & Gas industry. The environment that most Oil & Gas applications are dealing with can be extremely dangerous and it is critical that the proper equipment be sourced for such operations. "It is important that the individuals responsible for specifying and purchasing material handling equipment for use in these environments can properly identify any hazardous locations or areas per the U.S. National Electric Code (NFPA 70), IEC Standard 60079, and other applicable local, national and international standards to ensure compliance with these regulations and safe operation," (Joe Runyon, Columbus McKinnon)." In most off-shore operations there is a much higher potential for flammable gases and chemicals to be present. The presence of these hazardous materials means all off-shore applications are highly regulated and call for stringent guidelines to be followed to ensure the safety of the employees and the operation and to help prevent avoidable disasters from happening. 
In most hazardous applications, the use of mechanically spark-resistant materials should be strongly considered. Here at Ace, we stock and source spark resistant and explosion products from a host of vendors. One of the brands we carry, Chester Hoists, produces products that, “utilize solid spark-resistant materials such as bronze hooks, trolley wheels and brake ratchets as well as stainless steel load chain, hand chain and hook latches,” (Joe Runyon, Columbus McKinnon)
In some cases, the application may be a temporary installment or a process that is executed extremely infrequently and the budget for the project may not justify spending extra on completely stainless steel components, such as chain. Chester offers, nickel-diffused chains or copper-plated hooks for projects with, “…headroom constraints or to reduce costs for equipment that will be used infrequently or in temporary applications. In these cases, Chester also can provide plated components to reduce costs. For equipment that is relied on heavily and is required to maintain spark and corrosion-resistant qualities for the life of the equipment, we actively promote the lasting protection of solid spark and corrosion-resistant materials rather than plated components.” (Joe Runyon, Columbus McKinnon).
For all off-shore and hazardous hoist & crane applications, Ace Industries Inc. recommends the purchaser for the project consider,
  • The use of solid spark and corrosion resistant components including stainless steel load chain, wire rope, and hook latches; and solid bronze hooks, hook locks, and trolley wheels, with aluminum or stainless steel hand chains.
  • The use of plated chains, hooks, and wheels for temporary protection against sparking and corrosion.
  • The use of U/L, CSA labeled explosion proof control enclosures and explosion proof/spark resistant motors can be provided for Class 1, Division 1 and 2, Group C&D hazardous locations. (These motors and enclosures are also available from Chester Hoist with weather proofing for outdoor use and in offshore environments)
  • The use of Explosion proof NEMA 7 control pendants. (However, by utilizing intrinsically safe controls, Chester Hoist is able to provide NEMA 4 control pendants and limit switches which are not only weather resistant, but are also lighter and more compact than NEMA 7 pendants and limit switches.

If you are looking for a hoist for your Off-Shore/Hazardous application you may want to consider the Explosion Proof Cable King or Global King hoists.
