In accordance with example embodiments a hose reel system including a layout guide is provided.

A hosed-reeling apparatus comprising a hose reel and a rack having a front opening for demountably receiving and supporting the hose reel. The hose reel has two sidewalls, a connection member concentrically coupling the two sidewalls, and two spindles extending laterally outward from the centers of the two sidewalls, respectively. The rack has at least a base framework, and a locking structure configurable between an unlock position and a lock position. The base framework has two upward facing channels on opposite sides thereof for demountably receiving the hose reel spindles. The channels are accessible from thereabove when the locking structure is at the unlock position, and the channels are inaccessible from thereabove when the locking structure is at the lock position. Each of the sidewalls of the hose reel may have at least one straight outer edge, allowing the hose reel sit stably on a horizontal surface or a ramp.

The present invention provides a telescopic jacking stepwise rollback-type reel sprinkling irrigation machine, including a chassis, a locking-type reel, a sprinkling irrigation apparatus, and a stepwise driving apparatus. A locking channel in a circumferential direction is disposed on the locking-type reel. The stepwise driving apparatus includes a lifting cylinder, an upper caliper, and a lower caliper, and the upper caliper and the lower caliper are clamped to be mounted on the locking channel. Pressurized water is used in the telescopic jacking stepwise rollback-type reel sprinkling irrigation machine to drive the lifting cylinder to realize periodic lifting motion of the piston rod, so as to drive the upper caliper to move up and down to be engaged with the locking channel of the locking-type reel intermittently, thereby driving the locking-type reel to roll back intermittently to automatically reel in a sprinkling irrigation PE hose.

A mobile, coiled tubing drilling apparatus with a rotary drill head, includes a non-rotating mast on a mobile platform. The mast has mounted thereon an injector below a coiled tubing reel. The injector defines an operational axis for the coiled tubing. The rotary drill head is pivotally mounted on the injector so as to be movable between a retracted position away from the operational axis and an operating position in line with the operational axis. The rotary drill head includes a top swivel for non-rotating connection to the coiled tubing and a bottom spindle for rotating connection to a pipe section. The top swivel and the bottom spindle provide fluid communication between connected coiled tubing and connected pipe section during operation.

System and methods for marking a work area boundary of an autonomous vehicle are disclosed. A system may receive an indication that boundary marking for a work area is to be activated, and may transmit an activation signal to a marking actuator based on receiving the indication that boundary marking for the work area is to be activated. The activation signal may cause the marking actuator to begin marking the boundary as a vehicle, that includes the system, traverses the boundary. The system may store information that identifies a plurality of marked locations along the boundary. The system may determine that boundary marking for the work area is to be deactivated, and may transmit a deactivation signal to the marking actuator based on determining that boundary marking for the work area is to be deactivated. The deactivation signal may cause the marking actuator to stop marking the boundary.

An illustrated view of an exemplary retractable rope reel device for protecting a tiger tail or jetter hose of a jet truck and trailer mounted unit. The retractable rope reel device keeps the tiger tail in place and stops the jetter hose from dragging or scraping along an edge of a pipe or manhole and causing replacement or leaking of the jetter hose. The retractable rope reel device is useful for protecting users working on the jet truck and trailer from being in the road when retrieving a rope from a side cargo area of the jet truck and trailer. Further, the retractable rope reel device is useful for saving time and energy of the users from retrieving and returning the rope from the jet truck and trailer thus being more efficient and safer in the use of time and costs. The device has a canister with a retractable reel and a trigger on an inside of the canister. The trigger allows retraction of a rope that is coupled to the reel. The rope is coupled to a tiger tail for keeping the tiger tail securely in a desired position. The device has a bracket for attaching the device to a bumper and then can be removed or kept for future use.

A coiled tubing reel apparatus for a coiled tubing unit, suitable oil and gas well operations, is provided. A reel is supported at the outside edge of the reel rims, and driven by one or more drives which interface with the reel. The drives are offset from the rotational axis of the reel.

A wired vehicle fleet having a first vehicle connected with a supply unit by a first bendable connection element and a second vehicle connected with the supply unit by a second bendable connection element is controlled by a control unit to avoid a collision between the first and the second bendable connection elements.

A cable drum feeding tool is for a vehicle with a lifting device. The tool has a primary gripper arm arrangement with a primary first gripper arm and a primary second gripper arm extending parallel and spaced apart from each other via a spacing, and a connection element connecting the primary gripper arms, and a primary gripper arm mechanism for moving at least one of the primary gripper arms. The tool further comprises rotation mechanism having a respective pivot at the primary gripper arms adapted to engage with respective flanges of a cable drum. The tool further has an attachment arrangement for releasably attaching the tool to the lifting device of the vehicle.

A vehicle having a door slidably mounted on a shell. The vehicle includes at least one assistance device, comprising both a winder carrying a strap and a receptacle, the winder including a brake for braking unwinding of the strap from the winder, one of the winder and receptacle being fastened to the shell and one of the winder and receptacle being fastened to the door, the strap carrying a latchplate suitable for being reversibly attached to the receptacle.
