The star of the BMS arsenal of military-grade construction equipment, the Overseer Sky-Hauler makes several tonnes look like a feather, and enjoys a high level of mobility while deployed along heavy-duty rail lines.

— In-game description
The BMS - Overseer Sky-Hauler (also known as a Large Crane or Railway Crane) is a late-game logistics Vehicle designed to pickup and move shippables. It is built on Crane Railway Tracks and can only move on those. Its most distinctive features are the stilted legs holding the main body of the Crane, as well as the large, black control room holding the crane.
The BMS - Overseer Sky-Hauler has 2600 HP and is disabled under 50% health. It takes 125 Basic Materials to fully repair it from 1% to 100% health with a Hammer.
Interactions
The BMS - Overseer Sky-Hauler can be interacted in a few ways:
Can interact with most structures in proximity - press E or Shift + E
Pulls items from stockpiles twice as fast compared to on foot
Can pull three times the normal amount from stockpiles - press Shift + LMB
Able to be deployed and undeployed - press F
Can undeploy even when holding a very large shippable
Unlike other cranes, the Large Crane can deploy and undeploy in four directions which reduces deployment time
Can pick up any packaged shippable - holdRMBand pressLMB
Held shippable can be rotated - press A or D
Held shippable can be placed on the ground or on special locations - cursor icon relays information: crosshair = valid location, cog = special location
Due to the large cost and limited movement of the BMS - Overseer Sky-Hauler, it is only useful in logistical operations that use Locomotives and Train Cars. While it has a significant advantage with its long pickup range, this advantage is only useful in certain areas where space is limited, and the mass rapid transfer of equipment is of the upmost importance.
If the player is planning to construct it, make sure to be space-efficient and have Railway Tracks constructed underneath it. Additionally, plan accordingly to see if the need for crane movement is required, or you can bypass that by constructing and deploying other types of cranes in its place.
Tips
Despite being able to be locked, players should never lock a crane, as it inconveniences others
Large Cranes do not move slower when lifting a shippable
Trivia
The BMS - Overseer Sky-Hauler is currently the largest crane in the game, and has the longest reach of any crane currently in the game (a little more than 30 meters).
It is the only vehicle in the game that cannot be constructed inside, or near a world structure.
It is the only vehicle currently in the game that requires Oil to function. Unlike other vehicles, it requires fuel to operate (if it does not have fuel, it cannot move at all).
