A thrust management system for use with a pressurized hose in order to dissipate or distribute forces incurred by a user from handling the hose. The thrust management system includes a pad mount or bracket having a first elongated portion, a second elongated portion, and one or more support members disposed therebetween. The pad mount has a pad associated therewith.

Essential constructive elements of the currently known machines and devices, which work by means of vacuum blasting, are improved in the surface cleaning and engraving machine that operates via a vacuum jet process in order to enable more effective cleaning of different surfaces, further applications and simplification of the handling of the machine or device. With the modifications and additions made, the application options of the machine or device are increased, the potential of clogging the suction hose is reduced to a minimum, the service life of the machine is extended and the efficiency and operating options of the blasting hood are improved. For this purpose, technical and design details of an already known machine are supplemented and improved; there are, for instance, a metering device (3), additions to the blasting hood (6) and measures to extend the service life of the machine by using rock impact films (31).

A carrier assembly for holding a hose that includes a main body having a first portion movingly engaged with a second portion. There is a guide rail disposed on at least one of the first portion, and the second portion. Either the first portion or the second portion is configured with a gripper element, and a latch.

A waterjet cutting tool for radial connection to a wellbore casing for cutting the wellbore casing or associated components thereof is disclosed herein. The waterjet cutting tool comprises a waterjet nozzle for outputting a cutting solution at high pressure, the waterjet nozzle for connection to a cutting solution source; a radial adjustment unit for radially associating the waterjet nozzle to the wellbore; and an annular adjustment assembly for mount of the waterjet nozzle thereto, for allowing annular movement of the waterjet nozzle about a vertical axis of the wellbore.

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.

Apparatuses, components, methods, and techniques for selectively texturing concrete surfaces are provided. An example method of providing a surface portion of an architectural precast concrete wall panel with an abraded texture is provided. The method includes a step of spraying a surface portion of an architectural precast concrete wall panel with an aqueous-based particulate abrasive mixture under conditions adequate to at least partially abrade the surface portion. An example sprayer system for abrading a concrete surface is also provided. The system includes an aqueous-based particulate abrasive mixture dispenser including a spray nozzle arrangement. The system also includes a material communication assembly in abrasive flow communication with the aqueous-based particulate abrasive mixture dispenser. The system also includes a dispenser positioning arrangement.

The present invention relates to a mobile blasting apparatus for injecting abrasives onto the surface of an article to be processed, the mobile blasting apparatus comprising: a body; a frame structure including a first rail extending along a first direction; a first moving device which can move the position of the body reciprocally along the first rail; and an injection device coupled to the body so as to inject the abrasives. According to the present invention, all processes can be automated without workers' manual work, so that the overall working time is reduced even when an article to be processed is large in length or volume, and there is no concern that work over a long time, strong jets of abrasives, and noxious dust would cause harm to worker health.

The present invention is directed to a hydroblasting system comprising a head assembly connected with some conveyance, whether now known or hereafter developed. Such head assembly may comprise, for instance, biasing elements configured to provide such head assembly with a floating functionality stemming from, for instance, the creation of an independent suspension, thereby enabling such head assembly to traverse irregular topographies. Further embodiments of such a head assembly may be configured to enable the same to be used on work surfaces such as a ceiling or wall, via a pneumatic assembly configured to apply force to such head assembly. Such a head assembly may further comprise a rotating manifold configured to supply the applicator thereof with high pressure fluid, during angular misalignment between the fluid source and the applicator. Further embodiments may use sensors and computing systems to allow for the autonomous movement of such head assembly and/or conveyance.
