A method can include receiving information associated with a conveyance of equipment in a borehole via a cable. The method may further include determining cable tension values based at least in part on a model and at least a portion of the information and conveying the equipment in the borehole via the cable; acquiring a cable tension value via one or more sensors. The method may further include comparing the acquired cable tension value to at least one of the determined cable tension values and, based at least in part on the comparing, setting a cable tension limit for further conveying of the equipment in the borehole via the cable.

A method of checking belt tension of a belt extending between two or more pulleys includes providing a reference indicator defining a reference position relative to the upper surface of the belt in an undeflected state. A force/probe assembly is provided and has measurement markings. The distal end of the force/probe assembly is positioned on the upper surface of the belt at a midpoint of the span. A force is applied generally perpendicular to the upper surface of the belt using the force/probe assembly. The belt may be deflected a predetermined distance, as determined by using the measurement markings, and the force applied is measured, or a force is applied to the belt until the force is equal to a predetermined force, and the deflection of the belt is measured using the measurement markings. The belt tension is determined based on the force and distance during the deflecting step.

A load cell that is detachable from a suspension belt cable that is subjected to tension resulting from a suspended load; comprising a cell body with a rectangular parallelepiped configuration wherein the length is greater than the width of the cell body; at least one first, second and third protruding tabs projecting from a long longitudinal edge of the cell body and configured to mechanically couple with the suspension belt cable; and at least one strain gauge configured to be positioned above an intermediate zone of a long side of the cell body; such that the first, second and third protruding tabs are evenly distributed along the long longitudinal edge of the cell body and the first and third protruding tabs are positioned in on a distal plane parallel to the long longitudinal edge of the cell body; with the first and third tabs having protrusions that prevent the cell from shifting or coming off of the belt cable.

A tool strip mark generator capable of measuring applied force includes: a bottom surface on which at least a portion of a target surface made of a material capable of generating a tool strip mark, which is a tool-scraped stripe, is formed; a rotating member configured to be rotatable in a state of being spaced apart from the bottom surface; a moving member movable on the bottom surface by laterally coupling the rotating member to a coupling portion; a force sensor attached to one side of an outer peripheral surface of the rotating member and sensing force which is applied when a tool strip mark is generated on the target surface by inserting the tool; a measurer configured to measure an output signal of the force sensor and calculate information about the applied force; and a display configured to display information about the applied force calculated by the measurer.

An information related to the position of an actuator coupled to a cable which is coupled to a motor is received. A filter is used to provide an input to a motor controller coupled to the motor, to adjust torque on the motor such that a strength curve is implemented relative to the position of the actuator.
