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.
