Tower
crane General introduction
Microelectronic technique, information transducer technique and telematic technique are used in tower crane safety monitoring management system, which breaks through routine safety limiters functions, has simplifies electric cabinet wiring, more convenient debugging, better humanization and high control precision. QAKJ tower crane safety monitoring management system is domestic advanced technically.
Tower
crane Main technical parameters
1. Load moment: 200-4000KN.m
2. Hoisting capacity: 2-18t
3. Hoisting altitude: limitless; Max. radius: limitless; Max. slewing angle: 1080 ¡ã
4. Electric cabinet AC contactor control loop voltage: 220V, 50HZ
5. Working temperature: -20 -60C
6. Combined accuracy error: <5%
7. Mean time to double failure: 3000h
Tower
crane Main functional characteristics
1. Control tower crane according to moment curve completely at any point.
2. 3 hours operation record of every 0.5s can be used for tower crane inspection, general repair and accident judgment.
3. Judge operation of driver, refuse overload operation, and give warning and record working data.
4. Shows tower crane working parameters on display screen, driver can understand tower crane active state and make correct operation.
5. Noncontact measurement technology, convenient installation and longer using life.
6. High measurement accuracy, correct working decision.
7. Compact construction, simple wiring, and convenient installation and debugging.
8. Advanced operating function, user can complete all safety debugging in driver cabinet.
9. Main control panel cut power when radius achieve Lmax of Lmin lead control point, and trolley winch stop moving.
10. Main control panel compares calculate hook height and Hmax/Hmin according to current position signal, cuts power when hook height achieve Hmax or Hmin lead control point, and hook stop moving.
11. Main control panel compares current slewing angle and setting value, cuts slewing power when slewing over setting value, max. slewing angle ¡Ü 1080 ¡ã .
12. Main control panel compares current weight value(G) with system setting value(Gmax), cuts hoisting control loop power when G ¡Ý 105%Gmax, high speed hoisting can not be done if G ¡Ý 50%Gmax, give warning if G ¡Ý 90%Gmax.
13. Main control panel compares current load moment value(M) with system setting value(Me), cuts trolley winch power when M ¡Ý 105%Me, give warning if M ¡Ý 50%Me, trolley and hoisting mechanism change to lower stage.
