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

A refueling system, comprising a drum rotatable to wind and unwind a hose, a carriage guiding the hose and lineally displaceable along a shaft parallel to the longitudinal direction of the drum so as to follow the movement of the hose along the drum. The shaft allows the displacement of the carriage along its length. A motor is coupled to the carriage and displaces the carriage along the shaft. A first position sensor communicates with the carriage to obtain its position. A second position sensor communicates with the drum to obtain the position of the hose. A control system is coupled to the first and the second sensor, to compare their obtained positions and to operate the motor.

A frictionless service carriage system including: a shaft 1 having a first 2 and a second 3 helix-shaped guide in its surface, each helix shaped-guide 2, 3 defining a linear movement along the longitudinal axis of the shaft 1 of a carriage 4 in opposite directions and both helix shaped-guides 2, 3 crossing each other 2, 3 along the longitudinal axis of the shaft 1, wherein the carriage 4 includes a movable element 5 located successively in each of the helix-shaped guides 2, 3 and movable along the guides 2, 3, the movable element 5 comprising a set of rolling elements 6 along the first or second helix-shaped guide 2, 3 of the shaft 1 and configured such that in a crossing with the other helix-shaped guide 2, 3, the set of rolling elements 6 has at least two contact points with the helix-shaped guide 2, 3 for which it rolls.

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 cable reel is provided, in particular for a pipe inspection system, the cable reel having a frame and a cable receptacle. The cable receptacle is rotatably arranged on the frame, it being possible to wind a cable onto the cable receptacle and unwind it from the cable receptacle. The cable receptacle has an inner cage and an outer cage, with the diameter of the inner cage being smaller than the diameter of the outer cage. The inner cage is arranged coaxially with respect to the outer cage and is inside the outer cage. It is possible to rotate the inner cage and the outer cage independently of one another, and the inner cage is receives a first cable portion of the cable and the outer cage receives a second cable portion of the cable.

Provided is a cable laying method using a cable laying apparatus capable of changing a direction of a cable, the cable laying method including: (A) installing a frame unit; (B) arranging a trailer bogie loaded with a cable drum inside the frame unit without additional loading work; (C) rotating the cable drum, which is loaded in the trailer bogie, by an under roller part; (D) changing a withdrawal direction of a cable unwound from the cable drum by a traverse part of the frame unit; (E) supplying the cable, the withdrawal direction of which is changed by the traverse part, to a cable unwinding part located at the rear of the traverse part; and (F) supplying the cable passing through the cable unwinding part to a required place through a curvature guide part located at the rear of the cable unwinding part, wherein the traverse part is configured to change a direction of the cable withdrawn in a radial direction of the cable drum to an axial direction of the cable drum.

A cable reel includes an outer frame and a reel assembly. The reel assembly is installed on the outer frame. The reel assembly includes a left reel and a right reel. An inner bracket is arranged in the outer frame. The inner bracket includes a left bracket and a right bracket which are respectively connected with the left reel and the right reel. A telescopic cylinder for controlling the swing is arranged between the left bracket and the right bracket.

A detachable line guide is disclosed. A screw with a helical groove between threads is provided. A guide is positioned a fixed distance perpendicular to the screw and can travel laterally freely. A follower mount is detachably affixed to the guide. The follower mount has a follower that is biased into the groove. Rotation of the screw causes the follower to track the groove and move the follower mount laterally. The guide is configured for a line to pass therethrough. When the line exerts a lateral force above a predetermined threshold against the guide, the guide and the follower mount detach.

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

An assembly and method for deploying, retrieving, and storing a cable having a minimum bend radius onto a drum. The assembly may comprise a frame, a rotatable drum carried by the frame, a levelwind carried by the frame, and a powertrain. The levelwind may comprise a rail spanning at least the width of the drum, and a traversable carriage carried by the rail. The levelwind may also comprise a cable guide carried by the carriage, where the cable guide comprises an elongated chute having contoured walls. The contoured walls of the chute include no bends having a radius less than the minimum bend radius of the cable. The powertrain may be operatively connected to rotate the drum about the drum axis and traverse the carriage along the rail. In some examples, the contoured walls of the chute are coated with a supplmentary coating.
