Draft 1 Draft 2 CRANE 起重机 ALHZ HSE_training 009a. rev.1 Based on C-GS-17-0-2-A JHA(2010.06) HSE plan rev.A Table of content Background 背景 Description 描述 On July 13th, MCC is unloading the weight of 80t crane from truck. Due to space limit, the working position of 25t crane can not fulfill this mission. The distance between 3t weight and crane is 18m, which is beyond the 25t cranes working radius 16m. To save time, the cranes driver decided to slanting lift this weight to the ground to release the truck, When he pulled the weight from the truck which fell on to the ground. This dangerous act of lifting cause the back supporting leg of crane get off the ground about 50mm. 7月13日，MCC将80吨的起重机从卡车上卸载下来。由于空间的限制，25吨起重机工作的位置无法完成吊装任务。因为当时货物与起重机的距离为18米，超过了25吨起重机16米的工作半径。但是为了节省时间，吊车司机决定倾斜的将货物从卡车吊装到地面上。这个危险的吊装行为导致起重机的后方支撑腿离开地面50毫米。 Background 背景 Description 描述 One PSSI happened in ALHZ site - The 630t crane fell down after lift jobs finished when they removed its small support and beam 发生在ALHZ现场的一个PSSI：完成吊装工作后，当他们移除起重机的支撑时，这个630吨的起重机发生了侧翻。 Background 背景 Description 描述 Inspection to tower crane equipment acted on July 06 and defects are noted as below: 7月6日对塔吊进行检查，其缺点如下： Parts of tower crane platform and strutting structure deformed and damaged. 塔吊的部分平台以及钢结构发生变形和损害。 No screw bolt fastened for meeting stile joint, only binding by iron wire. 平台阶梯结合处的螺栓没有拧紧，且仅仅通过铁丝来固定。 Background 背景 Description 描述 Because the 2nd stage cooler core had leakage, so the client used the travelling crane to lift the core, but when they intended to put down the core to floor at about 5 meters, the core slide from slings to earth on sealing head side, then the other side of core hit the ground again. This incident made the flanges and nozzles on the sealing head bend, and the frame with blocks bent like wave. 由于2级冷却器内部存在渗漏，客户便使用移动式起重机将冷却器内核吊起。但是，当他们试图在距离地面5米的高度将冷却器内核放下时，内核的封头侧发生滑落，从而导致内核的另一侧撞击到地面。此次事故导致封头侧的法兰以及管口撞弯，同时导致整个换热器框架弯曲成波浪状。 Background 背景 Background 背景 Ba
