15-Ton Gantry Crane Control Description
The 15-ton gantry crane includes systems for traveling the long trolley, traveling the trolley, and raising and lowering the hook. The following control devices are installed on the gantry crane:
Central Control Cabinet: Designed with PLC connection to control crane operation and collect and store data (load, time, etc.). The HMI screen allows the operator to monitor crane operation, diagnose faults, and retrieve load data.
Load Sensors: Installed on each trolley to send data to the PLC
- Remote Control: Remote control units are installed on the gantry crane at the workstations, including:
- 1 Master Remote Control BDK 0: Provides overall control of the gantry crane operations and assigns control permissions to slave remote controls.
- 1 Slave Remote Control BDK 1 at Position 1
- Control Permission Indicator Lights:
The gantry crane is equipped with 1 set of indicator lights. Each set of lights has 3 colors: green, red, and yellow, used to indicate control positions for easy observation and operation, ensuring safety.
- Indicator Lights – DB – For Trolleys:
- Green: The Master Control Unit has control permission.
- Yellow: VT 1 / BDK1 has control permission.
- Red: Crane is stopped.
- Load Display:
Each trolley has 1 extended load display unit, allowing the operator to observe and know the lifting load for safe lifting and lowering.
Gantry Crane Control Operation Description
Remote control units operate the gantry crane.
- The Master Remote Control provides overall control of the gantry crane and can also distribute control permissions to appropriate positions, ensuring safety during operation.
The Master Remote Control is used to control the following operations:
- Gantry crane travel – when control permissions of slave BDKs have been turned off.
- Trolley travel – when control permissions of slave BDKs have been turned off.
- Hook lifting and lowering – when control permissions of slave BDKs have been turned off.
- Assign control permissions to the control units at Position 1; using the switches on the Master Remote Control.
Note:
- To ensure safety, once control permissions have been granted, the Master Remote Control will not be able to control the directions for which permissions have been granted.
- At any one time, each trolley can only be controlled by a single remote control unit at 1 position.
- Only the Master Remote Control can control gantry crane travel, on condition that control permissions from slave BDKs have been turned off.
