It employs motor of hoisting mechanism and reducer imported from Germany. The integrated and compact design of hoisting motor, reducer, reel and limit switch saves space for the user. Modular design increases the reliability of mechanism meanwhile reduces the time and cost for maintaining.
It has more and faster hoist speed and various pulley ratio which can be selected. The standard traveling mechanism of the trolley is controlled by converter, with speed of 20m/min, which makes a little swing and accurate position if hoisting items while trolley traveling as well as lifts precision and valuable items reliably.
The design strictly carries out the relevant standards of FEM. With aluminum alloy shell of the reducer; steady running and low noise; Lifetime lubricating (within safety service circle); Double-disk electromagnetic brake.
The reel is made of high quality seamless pipes and processed by numeral control machine, after the special finishing, the rope groove on reel works coordinately with rope guide to efficiently prevent rope loose and tangling.
Employ import steel rope with high strength which has tensile strength of 2160 KN/mm², with good safety performance and long service life.
Standard rope guider is made and processed by engineering plastics with strong abrasion resistance and good self-lubricating performance, which greatly reduces the wear of the steel rope as main force safety components and then enhances safety of hoisting mechanism. Meanwhile, direct to different use condition, the heavy-grade rope guide made of nodular cast iron is also allowed.
The hoisting mechanism employs double-winding squirrel-cage pole-changing motor to achieve speed ratio 1:6. Shell of motor is made of aluminum alloy by extruding, which has good dissipation. The fan is installed to the end of motor in order to enhance cooling effects. Thermal resistor (or the thermal switch) is embedded in to winding group of motor to prevent probable motor overheating.
The motor has F insulation level and protection level IP54.
As to the variable---frequency motor of hoisting mechanism, encoder is allowed to install, which is ordinarily installed to fan shaft end of motor.
The motor of hoisting mechanism is provided with double-disc electromagnetic brake. Brake integration locates at the end of motor. The brake will automatically close if the motor powers off in order that avoid load slipping off. The brake clearance does not need to be manually regulated (which can be regulated automatically by brake spring) after being initially set; if the thickness of brake pad is lower than the setting, it will automatic alarm through additional monitor switch in order to remind user to replace it. Double-disc electromagnetic brake is safe and reliable, the brake torque is higher than 1.8 times of rated torque, the number of braking gets to 1,000,000 times and it does not need maintenance in the safety service circle.
Have fast movement and high reliability.
It's maintenance-free and self-regulated.
Employ dustproof design and long service life.
Shell of the reducer uses aluminum alloy material, with weight and corrosion resistance. Semi-grease lubricant in full sealed box gets all gears lubricated fully and should not be changed within the design circle for safety service.
Every gear which gets the process of surface hardening and high-precision grinding ensures stable running of reducer.
It has small size and light weight.
Run smoothly and steadily and have low noise.
Have corrosion resistance and maintenance-free.
