Detailed Answer
A placing boom (concrete placing boom) remote control controls boom slewing, luffing, boom extension, and concrete pump start/stop; it needs 8-12 keys + multiple speeds (for precise placing). The LIDEER LD series fits placing booms; XINGJIA construction models are optional. Placing work has poor visibility, so the remote lets the operator stand at a safe position to watch the placing point. The pump E-stop must be reliable.
| Control | Slew/luff/extend |
| Precision | Multi-speed |
| Safety | Pump E-stop |
Note:The placing boom remote E-stop must be able to cut pump power.
