EMH, Inc., a Valley City, OH manufacturer of overhead cranes and components, has expanded its line of engineered wire rope hoists to allow the user to choose the most economical hoist with optimal performance for a specific application.
The HR line provides capacities up to 50 tons with 4/1 or 6/1 reeving. It is well suited heavy duty applications with high cycles, such as steel service centers. VFD control of hoist and trolley motors and a heavy duty gearbox make the HR hoist better suited for these applications than standard packaged hoists.
The HF line offers capacities to 100 tons with 8/2 or 12/2 reeving for True Vertical Lift. Like the HR hoist, it comes with VFD control and heavy duty gearbox.
Both the HR and HF hoist lines include:
o Half-depth drum grooves to eliminate the need for rope guides.
o DC disc brakes.
o Easy access to upper sheaves for maintenance.
o Class F motor insulation
o Three-position geared limit switch (lower and upper operational, upper security) with addition of upper weight operated limit.
o Standard closed Loop Flux Vector VFD hoist control.
o Standard VFD trolley control
o Standard Rotating axle trolley endtrucks.
o 40,000 hours of B-10 life (hoist motor gearbox).
o Rugged, durable motors and gearboxes with the added benefit of utilizing standard components such as drums, brakes, sheaves and wheels.
o High quality, efficient, quiet AGMA Class 11 gearing.
o Standard equalizer pin on trolley endtrucks prevent 3-wheeling
