An improved electronically controlled portable testing system provides one or more self-contained, automated testing skids configured to perform required tests on the exhaust output of a stationary engine. The testing skids are configured for easy transportation on a medium duty truck and in a preferred testing process, are deployed to the engine site (and reloaded on the truck after testing is complete) using a lift attached to the truck. Using these systems and methods, a single technician can concurrently test multiple exhaust stacks on engines separated by any distance, from 100 feet to miles apart. The testing skids provide the technician with wireless remote test control and monitoring. The disclosed systems and methods increase the efficiency, accuracy and repeatability of tests.

A method and system for piece-picking or piece put-away within a logistics facility. The system includes a central server and at least one mobile manipulation robot. The central server is configured to communicate with the robots to send and receive piece-picking data which includes a unique identification for each piece to be picked, a location within the logistics facility of the pieces to be picked, and a route for the robot to take within the logistics facility. The robots can then autonomously navigate and position themselves within the logistics facility by recognition of landmarks by at least one of a plurality of sensors. The sensors also provide signals related to detection, identification, and location of a piece to be picked or put-away, and processors on the robots analyze the sensor information to generate movements of a unique articulated arm and end effector on the robot to pick or put-away the piece.

A workover rig including a retractable mast, a drawworks system, a drive system, and an electric power assembly. The retractable mast is configured to retract from an extended position into a retracted position for transportation. The drawworks system is configured to control movement of one or more objects suspended from a crown of the retractable mast in the extended position. The drive system is configured to control the drawworks system. The electric power assembly is configured to electrically power and control the drive system. The electric power assembly includes a cooling system.

A vehicle is provided. In one embodiment, the vehicle includes a work implement and a cab positioned forward of the work implement. The cab defines a cab interior that includes a vehicle operator portion, an implement operator portion defined rearward of the vehicle operator portion, and an implement operator seat positioned in the implement operator portion that is configured to face rearward toward the work implement. In another embodiment, the vehicle includes a work implement; a cab positioned forward of the work implement; a vehicle operator seat mounted within the cab that faces a front of the vehicle; an implement operator seat mounted within the cab rearward of the vehicle driver seat and that faces a rear of the vehicle; and one or more controls mounted proximate the implement operator seat that are configured for operating the work implement. A system for operating a work implement also is provided.

An improved stack bed wagon is provided for pickup of one or more mid-size or big bales in an agricultural field for transport that simultaneously tilts and rotates a longitudinal bale 90 degrees upwardly and transversely over, adjacent, and along the forward upper edge of a stack bed for pushback onto the stack bed for transport or for consolidation with one or more similar bales in a single layer stack load on the stack bed that can be offloaded from the wagon to the field for later pickup and movement or that can be used for transport of the stack load for deposit in a different place or that can be used for the retrieval of a stack load from a field, ground, or storage surface.

A portable fluid filtration system. The portable filtration system includes a trailer having a ceiling with a predetermined height, and having an openable and closeable ceiling passage. One or more filter assembles are disposed in the trailer. Each filter assembly includes a filter base and a filter cartridge connectible and dis-connectible to the filter base. The filter cartridge has a height such that when it is disposed on the filter base, the filter cartridge extends beyond the predetermined height of the trailer ceiling. The system also has a fluid input/output assembly disposed in the trailer and fluidically connected to the at least one filter assembly, the liquid input/output assembly being for receiving fluid to be cleaned and inputting it to the at least one filter assembly and for receiving filtered fluid from the filter assembly and for outputting it. The system further has a rotatable, extendable filter cartridge mover disposed in the trailer, for connecting and disconnecting the filter cartridge to the filter base.

An assembly of a controller is to be arranged on a hydraulic lifting device, and a mobile control module can remotely operate the controller. Sensor data can be fed to the controller via signal inputs, and a processor of the controller calculates first information characteristic of the current position of the lifting device from the sensor data and from data specific to the lifting device stored in a memory. The controller has an operating mode in which parameters for a further position of the lifting device and/or for a lifting load can be input at the mobile control module. Second information characteristic of the further position and/or the lifting load is calculated from the parameters, and the stored data is compared with the first information and/or the specific data. The mobile control module and the controller communicate with each other in a wireless and/or wired manner.

A self-propelled flat-bed trolley is provided which includes a motor for locomotion and including a load-bearing platform and an articulated crane with a telescopic arm adapted to load and unload articles to and from the platform. The crane is maneuverable to locate the center-of-mass of the articles within a base of support for the trolley, with the trolley further including a controller for controlling the motor and articulated crane.
