Hoisting Motor
● Reserved for squirrel-cage inductor motor and the outer casting is made of gray cast iron. Insulation class E (6HP under), class B (6HP above). When the temperature reached 125°C (class H can bear high temperature till 180°C). Overheat protection of the motor coil will be started to prevent the motor from burning up.
● 250% of high-performance starting torque. The electric horsepower can be used with high frequency for long periods of time and quietly.
● Hoisting motor is classified as 30%ED with 180 times/hour switch frequency. (60%ED is optional.)
● The minimum protection is IP53. (IP55 is optional.) Standard single speed motor: 4P, 1740RPM;
Double speed motor: 4/8P, 1740/870RPM; Micro speed motor install dual motor on the both side
of gear box.
Gear Box
● Small size of all-planetary deceleration gears can run with a larger torque and low noise.
● Using enclosed oil type lubrication. It is made of processed alloy steel, as a consequence, the heat treated hardness is HRC45 degrees at least. All the shafts are used with anti-friction bearing.
● Noise level <=85dba @ 1M.
Wheel
● Turning from S45C material, heat-treated surface, bearing high pressure and good abrasive resistance.
Wire Rope
● The rope has at least 5 times safety factor, high tensional strength, wear-proof flexible
steel can endure bending fatigue.
Dual Overload Device
● There are 2 stages of upper limit switch. The first stage failed to cut off the circuit and the second stage cut off the main power, the emergency limit switch would insure security.
● When the hook touched the emergency limit switch, it cuts off main power supply instantly.
(Hoist would still under control when electromagnetic connector jammed.)
Brake System
● DC electromagnetic brake disc links up with the motor movement , faster reaction, better heat
dissipation and well braking force. While cutting off the power, it brakes automatically and
avoids to burn out. High safety ranking, easy adjustment .
Eccentric Shaft
● Auto-adjustment, granted with CNS new model no.40602, can run on uneven and still sustain the load evenly.
● Applicable for the medium tonnage operations (20~30 tons), low failure, and easy to maintain.
Control System
● Using famous brand of high volume electromagnetic switch which is designed by inching standard. It could be continuous used and high duty cycle. .
● Electromagnetic switch attach the mechanical linkage, coil is installed surge protector, safety and stable.
● Control voltage standard is 220V ( Option: 110; 48; 24 V). Inverter is available.
Drum
● 16 times greater than the diameter of cable reel. It meets the safety standard of fixed crane.
Sheave
● Made of gray iron casting. It is 18 times of wire rope diameter.
Push-Buttom Switch
● Reinforce plastic shell, one piece design, good insulation and long operating life. Able to endure the impact and resists fire.
● Control cable attached to high-strength steel wire to strengthen the security of installed suspension.
Hook Set
● Forged and heat-treated by alloy steel with high strength, high resistance against wear. With
thrust bearing enabling hook to swivel 360 degrees. The safe carrying capacity is more than
4 times. Equipped with safety latch to ensure operational security.
