  • Building hoist life 2012/10/15 1, the to adjust building hoist guide rails on both sides of the guide rollers, the adjustment of the essentials: the rail side of the guide wheel adjusted to the soft reduction in rail hand toggle wheel body should be able to rotate, but significant block is appropriate ; the other side of the wheel and rails shall to keep 0.2 ~ 0.5ram asked gap;2 by the above method and sequence adjustment tower crane hoists, hoists drive mechanism as one of the lifts hoists s...
  • Building hoist safety inspection calibration 2012/10/11 Building hoist safety device testing calibration project:1, the calibration of the measurement of the speed of the operation, the operation speed should meet standard requirements;Safety gear, the centrifugal speed limiting device is mounted on the bench, the use of test equipment such as a variable speed device, when the safety device of the centrifugal speed limiting device action to open given the operation speed for the selected gear speed modulation.2,Safe b...
  • Building hoist installation project management 2012/10/7 1.1 grasping quality strictly in accordance with the normsOrder contract for building hoist installation engineering and installation contracts, installation drawings, technical data, and construction and acceptance of norms "clearly put forward the requirements of the construction quality of the installation work. The goal of the installation and construction quality, is through the to install scientific management in the construction process, drawing tec...
  • Tower crane driver operation details 2012/9/28 For operating the tower crane such a large machine, in order to protect the safety of the construction process, the construction workers in the manipulation of the process need to pay attention to the details of what aspects of it?Experts pointed out that the tower crane. Quantity can not be more than 20% of the total amount of concrete tower crane, tower crane concrete label C30-35 to reach at least 63 series and over the tower crane must C35 concrete below 63...
  • Considerations of safety building hoist 2012/9/27 Overvoltage, undervoltage, wrong phase failure protection device when the voltage drop in the wrong phase and phase failure, over-voltage, electrical wiring, protective devices, building hoist stop running. Some on site, construction elevator maintenance personnel, does not exclude cause undervoltage faults relative failure of protective devices in a timely manner, but to cancel or shorted protection device, so that it does not work, to leave potential accident...
  • Tower crane slewing the system motor off axis precautions 2012/9/25 Tower crane height because the installation area by wind, in order toprevent the tower crane and capsized due to strong winds hit the towercrane premise "(GB/T9462-1999) delineation the slewing mechanism shouldbe agreed, in a non-working state, the boom roll freely with the wind,winds invasion tower crane to reduce wind area. Content with therequirements of the national standard, tower crane slewing reducer thecycloid reducer or planetary gear reducer, planetary...
  • Building hoist bearing burns 2012/9/24 (1) Failure Analysis: bearing burns caused by the bearing overheating of results building hoist operation. Its performance: the bearing temperature is too high, the bearing rolling off or peripherals grilled blue phenomenon occurs; bearing and housing expansion, "stuck" phenomenon. High temperature bearing the annealing occurred glued or even killed. The reason: runout between the shaft is too small. lubricant (grease) failed or improper lubrication. o...
  • Tower crane simple deal with the problem 2012/9/24 1,tower crane does not start properly.(1) whether the linkage Taiwan in zero span.(2) the circuit breaker is closed (FG FH FX FU1 FU3 DL1 DL2, etc.).(3) three-phase power supply is missing phase or phase sequence is correct (the indicator is green).(4) Check the start (ZC) contactor coil is burned out or loose connections off.2, the action chaos and failure.(1) control cable water or moisture, dry or replacement.(2) contact power can not be ejected. Wipe core dirt,...
  • Considerations of safety building hoist 2012/9/23 The safety device is a part of the building hoist to rely on it to eliminate hoists fall accidents, and to ensure the safety of the lives of the crew. Therefore very strict factory test of the safety device on the factory torque measurement, the measured critical speed, the spring is compressed measurement of the amount of each is accompanied by a test report, assembled into a construction elevator the statutory inspection units it after the drop test under the...
  • Maintenance of the building hoist parts 2012/9/20 1, the building hoist drive mechanical maintenance requirements:(1) The motor and worm gearbox to the mounting plate of the connecting bolts are secure.(2) coupling rubber ring depending on the wear replacement, also check the motor, gearbox shaft concentric.(3) Check the gearbox oil level and oil leaks.(4) Check the condition and health of the electromagnetic brake.2, the maintenance requirements of the standard section(1) standard section rack gear tooth contact ...
