Quality Standards<\/strong>\"Crane<\/td>\r\nEMH is a member of Crane Manufacturers Association of America (CMAA).EMH is certified to ISO 9001:2008 standards for design, manufacturing, installation, and servicing of overhead cranes.<\/td>\r\nHoist design conforms to all applicable national and local standard standards.You are dealing with an organization that continually reviews its management processes and meets internationally accepted standards.<\/td>\r\n<\/tr>\r\n
6 to 1 Hoist Speed Ratio<\/strong>\"6<\/strong><\/td>\r\nThe 6 to 1 ratio will provide better maneuverability, and using the slow speed can easily result in a fraction of an inch movement up or down. This will allow delicate positioning and precision spotting. In addition, the design is not load sensitive as the older variable speed control systems.<\/td>\r\n\r\n

  • Lifting and lowering can be\r\nexecuted safely and precisely<\/li>\r\n\t
  • Saves time<\/li>\r\n\t
  • Reduces load damage.<\/li>\r\n<\/ul>\r\n<\/td>\r\n<\/tr>\r\n
Severe Demand Hoist Motors<\/strong>\"Severe<\/td>\r\nOur pole-changing squirrel cage hoist motors are designed and built for operations that require frequent inching and spotting. They are totally enclosed and fan cooled and designed exclusively for crane and hoist duty. These 60 minute TEFC “F” insulated motors efficiently dissipate heat. Large braking surface ensures fast, precise stopping of load under all load conditions.<\/td>\r\n\r\n
