An apparatus includes a housing, a rotatable spool disposed within the housing, a belt at least partially wound onto the spool, a motorized retraction mechanism disposed within the housing, coupled to the spool, and configured cause rotation of the spool in a first direction for winding the belt onto the spool, and a tensioning mechanism disposed within the housing, coupled to the spool, and configured to prevent over-rotation of the spool in a second direction opposite the first direction while the belt is being dispensed from the spool.

A tool-operated adjustment device includes a housing supporting a rotatable spool that is operably coupled to a tension line. The spool is configured to rotate about a first axis in a first direction to wind the tension line, and to rotate in a second direction opposite the first direction to unwind the tension line. The device includes a socket pivotally coupled to the housing and configured to rotate about a second axis. The socket is selectively coupled to the spool to drive rotation of the spool in the first direction. The socket is configured to removably connect and disconnect to a tool configured to rotate the socket about the second axis. The device includes a release mechanism that is configured to selectively release the spool such that the spool is free to rotate in either the first or second direction in response to manual forces applied to the release mechanism.

A system of where internal friction otherwise known to be back pressure or resistance is eliminated and iterations of power transfers allows for a greater use of the effort put into the use of the device embodied within the 2 powered system, as presented here as to teach others how we, as in the use of shared and sustained power, may be able to reduce the consumption of power and where certain artifacts are taken to power stages within a hose. To aid in lessening the power needed when a material is compressed into a hose forcing a pump implemented in the duty range to produce such pressure is unduly burdened. To achieve equilibrium within the material delivery system by inducing movement and in doing so making the jerking action of energy transfer across unequal pressures to be relieved. The coordination of these simple components to the delivery that may be generated from this specification are to be considered the use of any of the parts as they are each unique to a developed system to deliver pressured materials through a hose. Operators of said equipment generated through this method may indulge in ease of operation within a lowered power range. This is a SAFETY METHOD.

A cable handling system at an electrically powered mining or construction vehicle that includes a skid-steered tracked or wheeled vehicle body which is powered for motion by an electric motor. The vehicle is supplied electric power either by an on-board battery and/or fuel cell or through a trailing electrical cable which is arranged to be wound onto and unwound from a cable reel on the vehicle body. The system includes a cable guide assembly that includes an arm member and a cable guide mechanism. A first end of the arm member is rotatably attached at a rear of the vehicle body to be moveable horizontally up to about 90 degrees in either direction around the rear of the vehicle body through an arc centered in the direction of a longitudinal axis of the vehicle body.

A vehicle-mounted reel utility with a cable dispenser. The cable dispenser has a swivel-aiming feature for figure 8'ing the cable. The cable dispenser is mounted to a swivel mount located at a free end of a positioning arm. The cable dispenser rotates about a pivot end of the positioning arm from a position parallel to a lifting arm to a position perpendicular to the lifting arm, and vice versa. The cable dispenser is also pivotally mounted to the swivel mount, allowing the user to swivel the cable dispenser about a horizontal arc while maintaining the cable dispenser in a central lateral position relative to a reel or a vehicle during the swivel movement. A hydraulic circuit controls the cable dispenser and an actuator that controls movement of a brake wheel from a contact to non-contact position, to coordinate the stopping of the reel and cable dispensing by the cable dispenser.

A device for winding up and unwinding an elongated flexible element having a free end and a spatially fixed end. The elongated flexible element is divided over its length at least into a use portion and a compensation portion, wherein the use portion has the free end and the compensation portion has the spatially fixed end. The device includes a rotatable drum configured on its circumference to wind up and unwind at least the use portion in a first winding plane, wherein the end of the compensation portion is spatially fixed relative to the drum. The elongated flexible element in the transition from the use portion to the compensation portion is fixed at a fastening point to the drum, and when the drum is rotated the compensation portion is coiled up and uncoiled in the form of at least one looped portion in a second winding plane.

A reel apparatus comprising a pipe; an outer flange assembly comprising two outer support walls connected to the pipe and wherein each outer support wall comprises an inner wall and an outer wall; an inner flange assembly comprising two inner support walls, wherein the inner flange assembly is rotated relative to the outer flange assembly and the pipe and wherein each inner support wall comprises an inner wall and an outer wall; and a motor assembly connected to the inner flange assembly and outer flange assembly, wherein the motor assembly is physically connect to the outer flange assembly and wherein the motor assembly is rotationally connected to the inner flange assembly.

Disclosed is a display device. A display device according to the present disclosure comprises: a housing having an opening; a roller extending longitudinally and located inside the housing; a display panel that is wound on or unwound from the roller and partitions a certain space into a first space and a second space when located outside the housing after passing through the opening; a sensor that is adjacent to a sensing area formed in at least one among the first space and the second space, and senses whether or not there are objects that have entered the sensing area; and a control unit that, on the basis of the information acquired by the sensor, controls whether to perform an operation for winding or unwinding the display panel on or from the roller.

A device including a platform and a drill connected to the platform. The device also includes a power source for powering the drill. The device also includes a cable connected to a cable reel and to the drill. The device also includes a stinger having a first end connected to the platform and a second end opposite the first end. The stinger includes a beam extending outwardly from the platform. The second end of the stinger connects to the cable. The stinger is configured to guide a position of the cable, relative to the platform, as the cable moves relative to the platform and relative to the stinger.

Winding device includes fixing member, reel, knob, connecting member, limiting component, and fastener. Fixing member is provided with check portion; toggle portion is provided at end of reel away from housing; first clamping member and linkage portion cooperating with check portion are provided at side of knob facing fixing member.
