1. Security monitoring system equipped with overload limiter, and displayed on the display with load tonnage, prompts the operator to prevent overloading.
2. Inspection system will automatically do self-test before crane start, including the power supply voltage level, phase inspection, zero protection and each safety device protection, etc.
3. Set lift limit switch, issued alarm when the hook near the upper and lower limit, automatically cut off the power when reach the upper and lower limit and automatic reset, so that the motor is running only in the opposite direction, to ensure that hook not breaking through the top.
4. Origin imported steel wire rope, breaking force not less than 2160N / mm², safety factor not less than 5.
1. The overall layout is parallel-type (C-type structure), which roll arranged in parallel with motor through the gearbox, with small limit size, compact structure.
2. Using German import driver module, matched with different pulley ratio, contributed to rich product series.
3. Electrical interface adopt aluminum alloy standard plug-in, safe and convenient.
1. Hoist and main girder operation adopt variable frequency motor, to reach stepless speed control, used in precision installation, with PLC programmable logic controller for anti-swing positioning and other functions.
2. The electric hoist with a light weight, low height, sophisticated configuration, high transmission efficiency, low noise, energy saving, modular manufacturing process, high maintenance-free rate and less wearing parts.
3. Remote control equipped with emergency stop switch, it is safe and simple to operate, adopt humanization design, accord with ergonomics principle, operating sensitivity is moderate, operation feel good, which can reduce fatigue during operation.
4. Hook design accord with ergonomics principle to improve the safety and operability.
1. Germany imported motor, insulation class F, protection class IP54. And has overheated protection and alarm functions, motor housing made of aluminum alloy molding, with excellent heat dissipation.
2. Use of maintenance-free electromagnetic disc brake, it is braking when power off to ensure safety. Brake pads material is environmental and asbestos-free, its built-in electronic modular system allows the brake fast and agile. Minimum braking safety factor is of 1.8, safety brake of not less than one million times. Even at high temperatures and during long operation, it can also ensure safe braking.
3. Germany imported reducer gear and gear shaft using 42CrNiMo materials, low carbon alloy steel hardened by carburizing and tooth grinding processing technology, gear surface hardness is above 60HRC, and gear manufacturing precision level is above 6.
4. Main electrical components use Schneider, Siemens, ABB and other international brands, electric control box protection class IP54.
Lifting motor adopt squirrel-cage cylindrical type 2/12 pole double-speed brake motor, fast and low speed ratio of 6: 1, electric hoist working level can be reached M6. Traveling mechanism adopts frequency control, the traveling speed of 2-20m / min.
Electric reverse braking, and then brake braking, making braking more quickly and smoothly, and also greatly reduces brake wear. Due to little wearing, no need to adjust the brake to improve the service life and reliability, 10 years maintenance-free.
Reducer adopts 10-year maintenance-free design. Gear precision is more than seven grades, with low noise, smooth operation. Internal gear set magnet for the adsorption of transmission wearing scrap iron, reduces gear wearing. Reducer is seal design, no drain and ventilation holes, lubricating use mineral oil, 10 years free replacement.
Sensors collect operational status and fault information, and real-time save memory, transferred to troubleshooting in the computer, optimizing the operation parameters.
