11.7.1. 小车运行操作
小车控制器位于操作员座椅的左侧。
位于座椅下面的“联锁”开关联锁小车驾驶功能。在就座之前，无法驾驶。
将手柄向前推，则小车向前行走。将手柄向后拉，则小车相应地后退。
小车行走速度为无级控制。
在您准备推拉控制器之前，确保吊具有向前与向后移动的自由空间，且吊具没有系松紧绳。
11.7.1.1. 限制
小车行走受位于小车活动范围的终端的硬接线的超行程开关的限制。在智能减速程序失灵时，这些开关可确保小车的安全停止。正常的小车行走由智能减速系统操纵，请参见后续页面上的说明。
小车机构受各种硬件与软件限制的限制。请同时参见图“小车速度曲线与限速”。

硬件限制
1． 超行程（柴油机侧）
a. 立即停止小车动作。
b. 向系统显示屏发出“故障22”信息。
c. 在未打开“起升装置/小车限制旁路控制”主开关（位于小车电气箱内部与司机室内的旁路开关，开关面板、保护旁路/开关）前，无法使用行走动作。
一旦发生超行程行走，在再次使用小车之前，必须对小车机械进行检查。
2． 减速检查（柴油机侧）
a. 速度检查点，如果速度高于主可编程序控制器（PLC）程序中的调整限值，小车驾驶将实施“快速停车”。（快速停车 = 紧急停车）
b. 向系统显示屏发出“故障48”信息。
3． 同步检查点。为主可编程序控制器（PLC）的位置检查输入参数。
4． 减速检查（柴油机对侧）
a. 速度检查点。
b. 如果速度高于主可编程序控制器（PLC）程序中的调整限值，小车驾驶将实施“快速停车”。（快速停车 = 紧急停车）
c. 向系统显示屏发出“故障48”信息。
5． 超行程（柴油机对侧）
a. 立即停止小车动作。
b. 向系统显示屏发出“故障21”信息。
c. 在未打开“起升装置/小车限制旁路控制”主开关（位于小车电气箱内部与司机室内的旁路开关，开关面板、保护旁路/开关）前，无法使用行走动作。
一旦发生超行程行走，在再次使用小车之前，必须对小车机械进行检查。
11.7.3. Operating trolley
Trolley controller is located on left of the operator’s seet .
Trolley drive is permitted by ”INTERLOCK” switch, which is located under the seat. Driving is
not possible before sitting down.
By pushing the controller forwards, trolley will travel forwards, and by pulling the controller
backwards, Trolley will travel accordingly backwards.
Trolley travelling speeds are steplessly controlled.
F
B
BEFORE YOU TRY TO MOVE TROLLEY CONTROLLER, BE SURE THAT
THE SPREADER HAS FREE SPACE TO GO FORWARD AND BACKWARD
AND SPREADER IS HANGING WITHOUT SLACK ROPES.
11.7.3.1. Limitation
Trolley travel is limited with hardwired overtravel switches, which are positioned at the end of
trolley travelling scale. These switches ensure safe stopping of trolley in case of smart slow-
down malfunction. Normal trolley travelling is guided by smart slowdown system, see descrip-
tion later on.
Trolley mechanism islimited byvarious hardware and software limits. See also picture ”Trolley
speed curve and speed limits”.

Hardware limits
1. Over travel DS (Diesel Side)
a. Stops Trolley motion immediately.
b. Gives message FAULT 22 message to system display.
c. Travelling motion is not possible to use without turning ”HOIST / TROL-
LEY LIMIT BYPASS CONTROL”key switch. ( Located at inside of Trolley
Cubicle and by--pass switch in the cabin, switch panel, PREVENT BY-
PASS/SWITCH)
IN CASE OF OVER TRAVEL, TROLLEY MACHINERY HAS TO BE CHECKED
BEFORE USING TROLLEY AGAIN.
2. Slowdown check DS
a. Checkpointforspeed,ifspeedishigherthatadjustedlimitintheMainPLC
program, Trolley drive will perform ‘FAST STOP’. (FAST STOP = EMER-
GENCY STOP)
b. Gives FAULT 48 message to system display.
3 Synchronization check point. Input for Main PLC program for position check.
4. ‘Slowdown check DOS
a. Check point for speed.
b. IfspeedishigherthatadjustedlimitintheMainPLCprogram, Trolleydrive
will perform ‘FAST STOP’. (FAST STOP = EMERGENCY STOP)
c. Gives FAULT 48 message to system display.
5. Over travel DOS (Diesel Opposite Side)
a. Stops Trolley motion immediately.
b. Gives message FAULT 21 message to system display.
c. Travelling motion is not possible to use without turning ”HOIST / TROL-
LEY LIMIT BYPASS CONTROL”key switch. ( Located at inside of Trolley
Cubicle and by--pass switch in the cabin, switch panel, PREVENT BY-
PASS/SWITCH)
IN CASE OF OVER TRAVEL, TROLLEY MACHINERY HAS TO BE CHECKED
