Henan mine crane co., LTD., oubiao hoist trolley, introduction
Oubiao hoist with German import car lifting motor, reducer.Lifting motor, reducer, drum, and the ceiling position switch integrated compact design saves the user's use of space.Modular design in enhanced the reliability of the institutions at the same time effectively reduce the maintenance time and cost.
Has faster lifting speed and more variety of pulley ratio to choose from.Standard car running mechanism is controlled by inverter, speed up to 20 m/min, make the car walks when lifting objects small swing, accurate location, can be lifting precision valuables safely and reliably.
drum
Drum made from high quality seamless steel tube by CNC machine tool processing and become, after finishing the rope on the drum groove with guide line which can effectively prevent slack rope and disorderly rope.
Steel wire rope
Wire rope using nominal tensile strength of 2160 kn/was imported high strength steel wire rope, good safety, long service life.
Rope guide
Standard guide line by the high resistance to wear and lubricating good engineering plastics processing and become, greatly reduce the wire rope wear the main stress components, thereby enhancing the safety of the hoisting mechanism.At the same time, according to different usage, can also provide the nodular cast iron production and manufacturing of heavy guidance on the rope.
Lifting motor
Lifting adopts double winding cage the change pole motor, realize 1:6 speed ratio.Motor shell composed of aluminum alloy control, good heat dissipation performance, hoisting motor end install a fan to enhance the cooling effect.All lifting motor winding is embedded with the thermistor (or thermal switch) in order to prevent the possibility of motor overheating.The motor insulation class is F, the protection class is IP54.For frequency lifting motor can be mounted to the encoder, the encoder usually installed directly on the motor fan shaft end.
brake
Hoisting machine is equipped with double disc electromagnetic brake disc.Brake integration, at the end of the motor when the motor power brake automatically closed, to prevent slip load.Brake the brake clearance after the first set of manual adjustment (clearance can be adjusted by the brake spring itself), when the brake lining thickness is lower than the set value through additional control switch can automatically alarm, prompting the user for replacement.Safe and reliable double disc electromagnetic brake disc, brake torque is not less than 1.8 times the rated torque, braking number up to 1 million, in the use of safety period without maintenance.
reducer
Reducer shell using aluminum alloy material, light weight, corrosion resistance.Fully half of grease lubricant sealed box to make all the gear can get sufficient lubrication, the use of safety in the design cycle without change of lubricating oil.
Every after surface hardening and high precision grinding processing gear reducer smoothly running.
Security and protection
Taken the steel wire rope electric hoist up and down limit stop using precise gear transmission type, when the hook is in (or below) when the limit position can reliably cut power circuit makes the motor stalling.
Taken the overload protector, wire rope electric hoist adopts electronic overload protector (with security monitors), to ensure total lifting hoisting will not exceed rated lifting weight bridge;When the wire rope tension is greater than the 105% rating, the overload protection device will automatically cut off the circuit.
European standard hoist trolley characterization
European standard hoist the car overall
