According to the direction of the truck lane, the installation of the reel should be on the diesel engine side or electrical room side, and the reel should be installed on the side away from the truck lane.

Add a reel platform on top of the diesel engine or electrical room. The cable reel and power switch control cabinet are both installed on this platform. The cable reel system adopts a single row multi-layer and bidirectional winding system. The operating voltage of the reel is set according to the actual situation of the user on site. The upper power supply cable length should be the effective one-way travel of the gantry. The slip ring box is made of 316L stainless steel with a thickness of ≥ 3mm and has wind and rain resistance and salt spray climate adaptability. Install a heater inside the slip ring box.

Cable Reel ERTG

Advantage:

1.       Proven and reliable technology with low maintenance.

2.       Supports continuous RTG operation without range limitations.

Disadvantage:

1.       High infrastructure investment.

2.       Limited RTG mobility; typically fewer than two RTGs can operate in the same block simultaneously.

3.       Manual cable connection/disconnection required during transfer, with higher safety risks in wet weather.

4.       High lifecycle cost due to frequent cable replacement.

5.       Cable snagging risks with vehicles and ground equipment.

6.       Diesel generator support is still required during transfer, can not realize zero-emission operation.
