Standard Design Features

FMH built-up hoists are designed for HEAVY SERVICE APPLICATIONS.
Our company size and structure, including in-house machining capabilities, allow us to respond to your material handling needs.

Trolley Frame: One-piece welded structure with load girts heavily ribbed and gussetted to resist vertical, lateral and torsional stresses. Deck plate is provided across the top of the trolley to carry hoisting machinery. Equipment is readily accessible from this upper deck. Lifting lugs are also provided.

Hoist Reducer: High quality cast iron gearcase is foot mounted and horizontally split. Helical gears are alloy steel, carburized to 60Rc then finished ground to meet AGMA class 12 standards. Shafting is heat treated, high-alloy steel mounted on spherical roller bearings. Splash lubricated and provided with duallip oil seals. Other features include oil level dipstick, inspection access cover, air breather, magnetic drain plug and lifting lugs.

HOIST MOTOR: Standard motor is foot-mounted Vector motor, blower cooled for continuous duty rating with class "H" insulation, thermostats and encoder. Fully flexible geared coupling used at motor output shaft. Lifting eye and easily accessible junction box are also provided. Wound rotor and DC motors are available.

HOIST BRAKE: Shoe brake is a foot mounted AC thruster designed for 150% full motor torque. Brake shoes are made from non-asbestos materials and are self aligning. DC and AISE are also available.

HOIST DRUM: Welded steel construction. Machined right and left hand grooving for true vertical lift. Drums are sized for a minimum 20:1 cable ratio and provided with half-depth grooving for improved wire rope life.

UPPER SHEAVES: Located above trolley deck for easy access with drop-in feature. Equipped with antifriction bearings. Running sheaves offer a minimum 20:1 cable ratio. Idler sheave ratio is a minimum 12:1.

WIRE ROPE: 6 x 37 IWRC extra improved plow steel designed for hoisting service. Sized for a minimum 5:1 safety factor.

LOWER BLOCK: Heavy, one-piece steel weldment. Sheaves are enclosed and fully guarded for added operator safety. Forged alloy or carbon steel hook is mounted on a roller thrust bearing for 360 degree rotation. A spring-loaded safety latch is also provided.

LIMIT SWITCH: Each hoist is provided with a weight operated upper limit switch and a rotary upper and lower geared limit switch. Overload protection is standard on all Flux Vector applications.

Some of our specialty applications
inlcude sludge handling, scrap handling,
coil handling, and remote-controlled nuclear waste handling cranes.

TROLLEY TRUCKS: Rotating axle wheels are supported by double row spherical roller bearings mounted in modified MCB type housings. Fabricated from structural tubing or welded box sections and accurately machined for trouble free operation. Double flanged wheels are made from C1045 steel and flame hardened to 425 BHN. Lubrication fittings, rail sweeps and bumpers are provided.

TROLLEY DRIVE: The drive consists of an integral brakemotor mounted to a helical reducer. The drive unit is shaft mounted on the drive axles and is splash lubricated in an oil-tight gearcase. Standard features include continuous duty, class "F" insulation, motor thermostats and DC disc brake.

OPTIONS & ACCESSORIES:  Auxiliary hoists, flame hardened drums and sheaves, centralized lube systems, outdoor and hazardous locations, weigh systems, power limit switches, base-mount design, stainless wire rope, rotating lower blocks, anti-sway reeving, operatar cabs, mill duty brakes, hook rotation locks, hydraulic bumpers, custom forged hooks, hand railings, coupling guards and below hook devices such as grabs, buckets, spreaders and magnets.
