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 7 lanes is 32 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:

• 1 Г— SIMOCRANE Truck Positioning System (TPS) V1.2, sensor controller
  Article No. 6GA7220-1AA00-0AC0
• 2 Г— SIMOCRANE Truck Positioning System (TPS) V1.2, 3D sensor
  Article No. 6GA7221-1AA21-0AB0

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

The mounting positions of the 3D sensors are selected so that both have an optimum view of the respective lanes. The following diagram shows the positions of the 3D 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:

• 1 Г— SIMATIC IPC477D, 19" touch display as an HMI device for the crane
  driver with SIMOCRANE CMS V4.3 installed as software, e.g.:
  Article No. 6AV7240-6DD17-0PA0, 6GA7214-0AB00-0AA0
• 1 Г— SIMATIC S7‑300, CPU317‑2 DP PLC as the crane controller, e.g.:
  Article No. 6ES7317-2AK14-0AB0
• 4 Г— LED signal encoder (with 3 LEDs) e.g.:
  Article No. L24757-C2323-A101
• 8 Г— support for fixing signal encoders 119 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 SIMOCRANE CMS, an application example from the version CMS V4.3, the customer can use CMS Lean. More information regarding CMS Lean please see Section SIMOCRANE CMS Crane Management System.
