What’re the Cautions for hoisting mechanism of Gantry Crane(PartI) ?
1, It must do the low-hanging test every time to check the braking performance. If necessary, adjust the brake clearance to meet the lifting requirements of gantry crane.
2, Under no circumstances, prohibit overload operation.
3, Making some protection measures to prevent spread stranding while cutting off the steel rope.
4, The steel rope installation should be in a clean environment. The dragging, construction need to prevent the program, grinding, rolling and excessive bending. The steel rope should be kept well lubricated, the lubricant should be consistent with the requirements and standards of the steel rope and don’t affect the visual inspection. The lubrication should pay special attention to the parts which have difficulty in checking and approaching, such as the balanced position at the wheel.
5, When replace the old rope with a new rope, ensure that there is no wear and tear on the pulley working guide slot and reel. If there is such condition, repair the guide slot to the original shape. During the steel rope replacements, check that there is no damage to the bearings and bushings to verify the pulley free running and no too much offset.
6, When the steel rope wound on the reel, the first layer should be close by and tension to maintain the minimum tension to wrap around the steel rope to finish.
7, If you are using the old rope to pull the new rope on the pulley, be careful to avoid any operation kinks on the old rope and be passed to the new wire rope. The condition will endanger the life span of the rope, more seriously, it will cause strand breaking or shape into the net.
8, The daily using steel rope should be checked every day including the fixed connection of the end part, the balanced wheel and make the safety judgment.
9, For safety consideration, the rope on the drum circle should be greater than 3 laps.
