The integrated compact design of the hoisting motor, reducer, reel and lifting limit switch saves the user's space. Modular design enhances the reliability of the organization while effectively reducing maintenance time and cost. The design of the lifting mechanism strictly implements the relevant standards of FEM.
Standard lifting motor is the two-speed variable-level motor (variable frequency hoisting motor for users to choose), all motors are cylindrical rotor. The standard degree of protection for the motor is IP55 and the insulation rating is Class F. The motor housing is made of aluminum alloy, the heat dissipation is good, and the hoisting motor is equipped with a fan to enhance the cooling effect. All winding of the hoisting motor are fitted with a thermistor (or thermal switch) to prevent possible overheating of the motor. The use of thermistors (or thermal switches) is in line with VDE0631 standard. Before the motor assembly, the stator winding must be 100% rigorous testing, test content and method in accordance with DIN EN60204-1 (VDE0113) related standards, including:
The rated motor is also tested according to the VDE0530 standard: (test duration is 1 second) U test voltage = (2 x U rated voltage + 1000V) x 1.2 For variable frequency lifting motor can be installed according to the requirements of the installation code The encoder is usually mounted directly on the fan shaft end of the motor.
Reducer shell with aluminum alloy material, light weight, corrosion resistance. The semi-grease-like lubricant in the fully sealed box allows all gears to be adequately lubricated without the need for replacement of lubricants during the design of the safe life cycle.
Each gear subjected to surface hardening and high precision grinding ensures smooth operation of the gear unit.
The lifting motor is equipped with a two-disc electromagnetic disc brake. The brake is integrated at the end of the motor and the brake is automatically closed when the motor is de-energized to prevent the load from slipping. Brake brake clearance after the first set without a manual adjustment (the gap can be adjusted by the brake spring), when the brake pad thickness below the set value through the additional monitoring switch can automatically alarm, prompt the user to replace. Two-disc electromagnetic disc brakes safe and reliable, the number of braking up to 1 million, in the safe use of the cycle without maintenance. According to the safety regulations, the braking torque of the selected brake not less than 1.8 times the rated torque of the motor.
The drum is made of high quality seamless steel pipe through CNC machine tool. After finishing, the rope groove on the reel can effectively prevent the occurrence of loose rope and rope.
Wire rope with a tensile strength of 2160 N / ㎡ of high-strength imported wire rope has good safety, long service life.
Standard guide rope with strong wear resistance and good self-lubricating engineering plastics processing, which greatly reduced the wear of the main force safety component of the wire rope is reduced, thereby enhancing the safety of the lifting mechanism. At the same time, for the use of different conditions, this will be provided by the ductile iron production of heavy-duty guide rope. Large, car operating agencies years of experience have shown that trolley travel mechanism can adapt to a variety of different working conditions, such as voltage instability or even worse conditions. Frequency conversion car running mechanism is the standard configuration of wire rope hoist, frequency conversion greatly reduces the lifting weight in the running process of shaking, and enhance the safety of the operation, while reducing the need for the operation cycle time and improve production efficiency.
Limit the size of small: increase the effective work area to reduce the height of the plant, saving construction costs
