The EXC-17 Excavator suit, more commonly known as the Excavator class power armor, was developed by Garrahan Mining prior to the Great War in collaboration with West Tek. It was designed to protect miners from rockfalls and airborne contaminants while increasing the speed at which they could work. Despite Garrahan's heavy advertising, the unit never entered full production and only five suits were known to have been made.
Created under the EX-17 Excavator Project, the suit not only borrowed elements of the T-45 power armor but was also spearheaded by a member of the T-45 development team, Harold Frost. The suit's parts were cast in black titanium to increase durability, as the extra punishment the arm units took when boring into bedrock caused damage to the suit. Atomic Mining Services were contracted to obtain their patented ultracite ore to power the armor, as the previous reactor caused overheating and stability issues.
The suit later publicly failed during the "Man Vs. Machine" mining competition against Hornwright Industrial's auto-miners, and all operations involving the suit were on hold until the company could re-evaluate their situation.
Excavator power armor provides a bonus of increased mining speed when both arms are used in tandem, and the helmet also prevents damage and disease from airborne and waterborne hazards. The suit was built with patented "Ore Sniffing" technology, and the helmet sensor calibration protocols are proprietary information and require registration interface with Garrahan's Mainframe.
Registering the helmet is required to complete the Miner Miracles quest but has no effect on the use of the power armor. Excavator power armor has good Radiation Resistance. It has the poorest Damage and Energy Resistances of any power armor model at the same level but wearing a full set of Excavator power armor increases carry weight by 100. Wearing a partial set has no carry bonus. If a piece wears completely out, it is removed from the chassis, removing the carry bonus. When mining ore veins of some metals while wearing a full set of Excavator armor, mining will produce four times the ore per attempt. This does not seem to alter the number of attempts made, so this seems to produce four times the ore per vein. The specific metals with this bonus are listed in the table to the right. This does not seem to work on ore deposits.
There were supposed to be five suits made, there are no locations with existing Excavator power armor. The Excavator power armor can be crafted during the quest Miner Miracles after downloading its schematics from a terminal in Garrahan Mining HQ in the R&D section, which is on the left after coming through the main door. The terminal is located in a large room on a center table, where there are two power armor stations. Once crafted, pieces cannot be upgraded to a higher level. To obtain a higher level set, the player character must craft it. This can be done at any power armor station.
