Mobile Construction Crane (Increased Construction Range)

Often run into the issue with large complex builds where trucks can't reach parts to deliver construction materials, rather than just increasing their range I thought it might be much more interesting gameplay wise and visually to have mobile construction cranes with a greatly increased delivery radius.
Some ideas to how they could function;
- They would be unlocked through research, either with or just after large vehicles.
- Ideally they would only get into position for jobs that is out of range for trucks.
- Trucks would deliver construction materials to them (this could be automatically or through a dedicated truck assigned to them).
- They would be only for construction tasks so would not deliver to storages or input products.
- Also possibility for additional tiers further down the tech tree though this might be unnecessary.
