SPAN-GUARD Industrial Power Systems for Crane Electrification are durable, reliable and safe even in the harshest climates and environments. Whether you require crane electrification on your shipping dock or over caustic tanks of acid, you need a rugged Power Supply System that won't let you down. The SPAN-GUARD Crane Electrification System owes its durability to its patented self-sealing soft vinyl cover which protects the conductor from cruel environments. Capable of running joint-free at lengths up to 2000 feet SPAN-GUARD eliminates the power loss and overheating associated with the unreliable joints of other heavy industrial power systems.
Our spring-loaded collectors use a carbon-graphite shoe and are more reliable and less costly to maintain than wheel based Trolley Systems because fewer moving parts require less maintenance. The Carbon graphite collector shoes are manufactured slightly softer than the conductor, which extends the life of the conductor bar and reduces maintenance needs. The spring loaded collectors automatically compensate for misalignments between the trolley electrification bars and the crane runway, and are engineered to handle the sag caused by temperature differentials of up to even 100o F.
Available in 250 and 520 Ampere models SPAN-GUARD can be cut to your specification and can accommodate all of your AC or DC Crane Electrification needs.
