They move loads ranging from a few hundred kilograms to tens of tonnes reliably and safely through countless cycles across equipment lifetimes measured in decades. The most fundamental requirement of any hoist or crane drive &#8212; beyond torque capacity &#8212; is the unconditional prevention of uncontrolled load descent under any condition, including motor trip, power failure, and mechanical fault.<\/p>\n<p style=\"font-size:1.05em;margin-bottom:18px;\">\u306e <strong>\u30a6\u30a9\u30fc\u30e0\u30ae\u30a2\u6e1b\u901f\u6a5f<\/strong> is uniquely positioned to meet this requirement.
