This invention relates to a transport system for moving at least one automated maintenance device for large substantially perpendicular surfaces, for example ship hulls, comprising a monorail system which can be laid freely and at least one drive device which can be moved on the monorail system along a movement direction. The at least one drive device has a drive unit with at least one running wheel, and the running wheel can be driven via at least one drive, preferably an electric drive. At least one pressing unit, is provided which is connected to the drive unit). The at least one pressing unit has at least one loading roller which can be pressed onto the monorail system via at least one spring element, and/or a fixing device is arranged on the drive unit, wherein a fixing roller is provided which interacts with the monorail system.

A system and method for blasting an overhead surface is disclosed herein. The blaster system can comprise a first enclosure, a second enclosure, a pair of recirculators, a pair of loader valves, and a pair of propeller assemblies. The first enclosure can comprise a pair of primary ports, and a pair of control cages. The pair of primary ports can be at the front surface of the first enclosure. The primary ports can receive abrasive material. The pair of control cages can be attached at the bottom surface of the first enclosure forming a pair of curved surfaces, and a plurality of gaps. Each of the curved surface can comprise a slot. Each end of the slot can rest within each of the gaps such that the abrasive material received within the first enclosure can collect within the gaps and falls into the slot.

A system for blast-cleaning a barge deck, sides, and fittings providing for safety and avoidance of damage to the barge and to persons, where a barge is blast-cleaned with moving blaster units suspended from and traveling along an overhead track beam. In one embodiment, the moving blaster units are each controlled by a person in a moving operator capsule moving in tandem with a moving blaster unit. In another embodiment, the moving blaster units are robotically controlled from a robotic controller which has access to a three-dimensional plan of the barge, communicating with the robotic blaster units via RF antennae, and receiving real-time data from sensors located on each blaster head. Optionally, the system for blast-cleaning a barge can provide blaster-head cameras for real-time remote monitoring of operations and for recording of the operations allowing review of any issue, such as damage, that might arise.

A surfboard multitool has a handle with a fin key or screwdriver inserted into one end for storage, and the other end terminating in a brush on the front side and a fin removal tool on the back side. The fin removal tool has two fin grippers that are placed around a surfboard fin in use, and pivoted to remove the fin from its fin box. A fin key or screwdriver is stored in the end of the handle. Between the fin removal tool, brush, and removable fin key or screwdriver, an all-in-one multitool for the most regular tasks in surfboard maintenance is provided.
