If the brakes do not hold, lower the load to the floor slowly and do not operate the crane. Report the situation immediately and DO NOT USE until repaired. 当吊物重量达到或接近吊机额定载荷时,应当测试吊机起升装置抱刹,即当吊物上升到离地面几英寸后通过切断总开关或关闭停止按扭来完成。若抱刹不 能承受起吊物重量,则吊物会缓慢掉至地面, 此时禁止使用该吊机并立即向上级 报告 软件系统测试报告下载sgs报告如何下载关于路面塌陷情况报告535n,sgs报告怎么下载竣工报告下载 吊机 故障,直到吊机被修好后方可投入使用。OVERHEAD CRANE OPERATION 行车和龙门起重机操作 null Ensure that all loads are lifted high enough to clear obstructions before moving the bridge or trolley. Whenever possible, maintain a minimum clearance of one foot above loads and to the sides. Raise the load only to the height necessary to clear lower objects. 在移动桥架或或大车之前确保吊物被吊起足够的高度以避开所有的障碍物。无论何时,只要有可能,应在高度方向及侧面方向预留的间隙至少为1英尺(约30厘米),这样当吊物上升至所需要的 高度时可以避开下方的物体。 Never pull a hoist by the pendant cable. 禁止拽下垂 的控制电缆。 OVERHEAD CRANE OPERATION 行车和龙门起重机操作 null Never leave the controls unattended while a load is suspended.
