垂直运输安全技术交底

一、 塔式超重机作业安全技术交底
（1） 作业条件
（2） （1）超重机路基和轨道的铺设，必须严格按照原厂使用规定及符合以下要求：
（3） ①轨距偏差不得超过其名义值的1／1000；
（4） ②在纵横方向上钢轨顶面的倾斜度不大于1／1000
（5） ③两条轨道的接头必须错开。钢轨接头间隙在3～6mm之间，接头处应架在轨枕上，两端高差不大于2mm；
（6） ④距轨道终端1米处必须设置极限位置阻挡器，其高度应不小于行走轮半径；
（7） ⑤路基旁应开挖排水沟；
（8） ⑥起重机在施工期内，每周或雨后庆以轨道基础检查一次，发现不符合规定时，应及时调整。
（9） （2）起重机的安装、顶升、拆卸必须按照原厂规定进行，并制定安全作业措施，由专业队（组）在队（组）长负责统一指导下进行，并要有技术和安全人员在场监护。
（10） （3）起重机安装后，在无载荷的情况下，塔身与地面的垂直度偏差值不得超过
（11） 3／1000。
（12） （4）起重机专用的临时配电箱，宜设置在轨道中部附近，电源开关应合乎规定要求。电缆卷筒必须运转灵活、安全可靠，不得拖缆。
（13） （5）起重机必须安装行走、变幅、吊钩高度等限位器和力矩限制器等安全装置，并保证灵敏可靠。对有升降式驾驶室的起重，断绳保护装置必须可靠。
（6）起重机的塔身上，不得悬挂标语牌。
Vertical Transportation Safety Technology Details

First, overweight and machine operation safety Tower Technology Details
(1) Operating conditions
(2) (1) overweight roadbed and track laying machine to be used strictly in accordance with the original requirements and meet the following requirements:
(3) ① gauge deviation of not more than its nominal value of 1 / 1000;
(4) ② in the vertical and horizontal direction of the tilt of the top rail is less than 1 / 1000
(5) ③ two tracks of joints must be staggered. Rail joint gap between the 3 ~ 6mm, joints should be mounted on the sleepers, both ends of the height difference of less than 2mm;
(6) ④ 1 m away from the track end position stop device must be set to limit its height should be no less than the travel wheel radius;
(7) ⑤ embankment next to the excavation of drainage ditches should be;
(8) ⑥ crane during the construction period, in order to track weekly basis or after the rain celebrate checked and found that non-compliance should be timely adjusted.
(9) (2) the installation of cranes, lifting, demolition must be in accordance with the original provisions, and to develop measures for safe operation, by a professional team (group) in the team (group) is responsible for reunification under the guidance of, and for technical and monitoring the presence of security personnel.
(10) (3) crane installed, in case of no load, the tower and degree of deviation of the vertical surface shall not exceed
(11) 3 / 1000.
(12) (4) Crane-specific temporary power distribution box, should set the middle of the track near the power switch should be in line with specified requirements. Cable reel to run flexible, safe and reliable, no rope.
(13) (5) The crane must be installed on walking, amplitude, hook height limit and the torque limiter device safety devices, and to ensure that sensitive and reliable. On a lift crane cab, broken rope protection device must be reliable.
(6) tower crane body, shall not be hoisted placards.
