FITOP Hoist

HOIST BRAKE

● DC disc brake with two flat-faced brakes discs(asbestos free) with a life of more than 1 million actuations, patent pending.
● Oversized brake disc’s lower surface stress and prolong brake life, frequent adjustments are not necessary.
● Holding brake can be manually released to lower the load in the event of a power failure or malfunction without special tools.

OVERLOADLIMIT

● New Design: The load-limiting clutch does not break the kinetic bond between the holding brake and the lifted load , patent pending.
● External Access: The hoist gearbox does not have to be disassembled to service the load-limiting clutch.

EXTRA HEAVY DUTY HOIST CONTROL

● Telemecanique ( Square D ) magnetic contactors chosen specifically for extra heavy-duty service have a rated life of more than one million cycles.
● Reversing contactors are mechanically interlocked for added safety.
● 24 Volt , low voltage control transformer standard. (48 Volt option.)

GEAR BOX

● Multi-Stage high performance gear train , gear teeth are precision machined for long life and quiet operation.
● Planetary gear drive used for the final high torque reduction , all forces are balanced.
● Permanently lubricated for life.

PUSH BUTTON STATION

● Molded reinforced high insulation plastic housing is impact , weather , corrosion and fire resistant.
● Double insulated design.
● Push button switches are mechanically interlocked for added safety.
● Strain relief cable is molded into the pendant cord.

TRUE MODULAR DESIGN

● Hoist motor can be removed with the hoist fully loaded. Chain sprocket can be removed without disassembling the gearbox . Load limiting clutch can be serviced without opening the gearbox .
● Plug in the push button and power cord.

CHAIN SPROCKET

● CNC machined alloy steel lifting sprocket is heat treated for maximum performance.
● High precision chain sprocket has more than 5 times the life of an investment casting sprocket.
● Advanced modular design enables replacement of the lifting sprocket without dismantling the hoist gearbox and without the use of special tools.

LIMIT SWITCH

● Upper and lower limit switches can be adjusted to stop the hook in any position.
● Limit switch has built in chain guides to safely stop the load in the event of twisted or damaged chain, also prevents non-vertical lifting.

LOAD CHAIN

● Grade 80 super alloy load chain is precisely calibrated and heat-treated for long life.
● Safety factor is more than 6-1.
● Surface hardened chain standard.
● Non-Acid processing galvanized plating chain can be choosed for resistance against corrosion.

HOOK

● Drop forged from alloy steel and heat-treated for strength and toughness , will not fracture but open slowly when overloaded.
● Equipped with safety latch and 360° swivel hook.

HOIST MOTOR

● Squirrel cage parallel rotor motor designed specifically for hoist duty.
● Modular design facilitates maintenance , the hoist motor can be removed with the hoist fully loaded for testing and or replacement.
● Separate mounting of the motor and brake prevent local heat buildup.
● Motor housing is extruded from aluminum alloy.
● Cooling fins increase surface area for maximum heat radiation.
● Class H insulation standard 180°C rise from 40°C ambient.
● Thermal protection via 145°C rated N.C. overload switch embedded in motor windings.
● Duty rating is 60%ED, 360 starts per hour for single speed three phase hoist , equal to HMI Classification H4.
● TENV and IP54 totally enclosed construction can withstand harsh environments. (IP55 option)
● Single speed 4 pole (1800 RPM) motor standard, two speed-two winding 4/12 pole(1800/600 RPM) 3/1 ratio motor and control optional.
