This application example describes a common solution for positioning terminal vehicles under a container quay crane.

Application example

The system supports the truck driver during parking with the aid of a simple control signal. A signal unit visible to the truck driver should be mounted at each corner of the crane. The crane driver operates the system and specifies the lanes in which loading takes place and from which direction the trucks arrive. The system must be able to operate two adjacent lanes at the same time (tandem mode). The operating range with the 7В lanes is 32В m wide overall. On the basis of the presets for lane and direction of travel, the system must be able to position different trucks and trailers independently.

Crane with TPS

Solution

In order to fulfill this function, the following SIMOCRANE products are required:

• 1В Г— SIMOCRANEВ TruckВ Positioning System (TPS) V1.2, sensorВ controller
  Article No. 6GA7220-1AA00-0AC0
• 2В Г— SIMOCRANEВ TruckВ Positioning System (TPS) V1.2, 3DВ sensor
  Article No. 6GA7221-1AA21-0AB0

The required width of working area between the crane uprights of up to 32В m can be operated because the 3DВ sensors are mounted at the bottom of the gantry bar. This corresponds to a typical 3DВ sensor installation height of approx.В 13 toВ 15В m above quay level.

The mounting positions of the 3DВ sensors are selected so that both have an optimum view of the respective lanes. The following diagram shows the positions of the 3DВ sensors and the lanes assigned to them.

Arrangement of 3D sensors

In addition to the SIMOCRANE products, additional components are required for operating the system and for displaying positioning signals. The following list contains suggestions for Siemens products that are ideal for this task:

• 1В Г— SIMATIC IPC477D, 19" touch display as an HMI device for the crane
  driver with SIMOCRANEВ CMSВ V4.3 installed as software, e.g.:
  Article No. 6AV7240-6DD17-0PA0, 6GA7214-0AB00-0AA0
• 1В Г— SIMATICВ S7‑300, CPU317‑2В DP PLC as the crane controller, e.g.:
  Article No. 6ES7317-2AK14-0AB0
• 4В Г— LED signal encoder (with 3 LEDs) e.g.:
  Article No. L24757-C2323-A101
• 8В Г— support for fixing signal encoders 119В mm, e.g.:
  Article No. C24121-A35-C93

The product SIMOCRANE TPS has a standardized interface to SIMOCRANE CMS. SIMOCRANE CMS contains pre‑configured WinCC sample images for operating and monitoring TPS. TPS is operated in the cabin on the PC 477C Panel that has a Client‑Server connection with the main CMS computer.

For cranes without SIMOCRANEВ CMS, an application example from the version CMS V4.3, the customer can use CMSВ Lean. More information regarding CMSВ Lean please see Section SIMOCRANEВ CMSВ CraneВ ManagementВ System.
