As shown in Fig.1.3-34, the hoisting ropes are released from the wire rope drum, passing through the rope discharging mechanism to go over the guide pulley on tower head down into the pulley of hook weight limiter in the slewing tower.53TC7030B 使用说明书 Operating Instructions It runs further to the trolley and hook pulley block. It finally passes through the rope clip and gets fixed by pins to the anti-torsion device at the jib head.1.3.4.4 接电源及试运转 Power on and Trial operation 当整机按前面的步骤安装完毕后，在无风状态下，检查塔身轴线的垂直度，允差为 4/1000；再按电路图的要求接通所有电路的电源，试开动各机构进行运转， 检查各机构 运转是否正确(详见有关章节)， 同时检查各处钢丝绳是否处于正常工作状态，是否与结 构件有摩擦，所有不正常情况均应予以排除。 After the installation of the whole crane according to the steps above, check the tower body axis for verticality at no wind conditions. The deviation tolerance is 4/1000. Switch on power to all electric circuits according to the electric circuit diagram and start all mechanisms for test run. Check mechanism for proper operations (for details, refer to relevant instructions). At the same time, check wire ropes at different locations for normal working status and for any friction with structure member. Remove all abnormal cases. If the tower crane needs to be put into service immediately after the installation, the safety device must be adjusted as specified in section 7 1.3.4.5 换倍率系统 Fall-change system 自动换倍率系统包括载重小车， 上滑轮组以及下滑轮组(含吊钩)三部分， 在 起 重 其 臂上的安装(图 1.3-35)和钢丝绳在载重小车，上、下滑轮组处的绕绳(图 1.3-36)。上滑 轮组与下滑轮组的连接与分离便可实现二、四倍率的变换(下面称为变倍率)。 The automatic fall-change system consists of 3 parts, i.e. the trolley, upper pulley block and lower pulley block (incl. hoisting hook). Their mount on the jib (Fig.1.3-35), rope winding on the trolley and upper-lower pulley blocks (Fig.1.3-36) and the connection-disconnection of the upper pulley block to lower pulley block enable conversion of 2-fall and 4-fall (referred to hereinafter as fall-change).54TC7030B 使用说明书 Operating Instructions 变倍率是在无载荷、 低速、 没 有摆动的情况下，在吊臂根部进 行的。无论是二倍率变四倍率， 还是四倍率变二倍率，都必须先 将旁路开关旋转至旁路状态，使 高度限位不起作用； 转换完成后， 必须将旁路开关恢复原有状态。 在二倍率工作状态下，装有自动 连接装置的上滑轮组(1)由于钢 丝绳的张力而紧贴起重小车。 The fall-change is converted at the jib root section under the conditions of no-load, slow speed and no swing. No matter how it is required to convert 2 fall to 4-fall or to convert 4-fall to 2-fall, the by-pass switch must at first be turned to the by-pass status to disable the height limiter. After conversion completion, the by-pass switch must be restored to its original status. At the 2 fall working conditions, the upper pulley block (1) with automatic connections contacts tightly the trolley. 上、下滑轮组的自动连接是通过两块连接板(2)进行的。连接板上开有长腰形孔(3)， 以使用下滑轮组上的销轴(4)连接并销紧。 The upper pulley block is connected automatically to the lower pulley block through 2 connection plates (2). The plates have waist-shaped long holes (3) for connection and locking through pins on the lower pulley block. 上、下滑轮组的分离由开锁装置(5)控制，此装置用弹簧(6)固定在小车上部。当载重 小车移动到起重臂根部时， 固定在臂架下面的楔块(9)通过它作用在连接板(2)上， 使连接 板(2)张开，上、下滑轮组即分离。 The upper pulley block is disconnected from the lower pulley block through the unlocking device (5). This device is fixed on the upper portion of the trolley by spring (6). When the trolley moves to the jib root, a wedge piece (9) under the jib acts on the connection plate (2) through this device so as to open the plate (2), thus the upper pulley block is disconnected from the lower pulley block. 1.3.4.5.1 二倍率变四倍率的转换方法 Method for 2-fall to 4-fall conversion (Fig. 1.3-37) 1.3.4.5.1.1 变换前，上滑轮组(1)紧贴载重小}
