One embodiment relates to an improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The retraction system is configured to selectively engage the retracted state with a trigger assembly which is slidably externally coupled to the connection system. The trigger assembly further includes a coupling member coupled with the plurality of cam lobes via a plurality of retractor wires, at least one trigger cable fixably coupled to the coupling member, a trigger coupled to the at least one trigger cable, a sleeve member intercoupled between the coupling member and the trigger.

An improved bolt hanger defines a hanger that exerts an outward force on the bolt that secures the hanger to a rock wall, urging the bolt outwardly under tension, and thereby helping to prevent the bolt from coming loose over time. The improved bolt hanger has a concave shape formed into it centered around the bolt hole. As the bolt is tightened into the bore in the rock, the head of the bolt (and/or an underlying washer) causes the concave portion to compress. This compression causes the concave portion of the hanger to exert an outward force on the bolt, which makes loosening the bolt more difficult. Furthermore, the hanger according to the present invention has a complex geometry on the rock-contacting surface that aids in the prevention of rotation of the hanger when under load. The bolt hanger may be used with a modified bolt adapted for use with the improved hanger.

A climbing tool for work positioning on a rope, usable as an ascender, speed control descender, lanyard rope grab and fall arrest device. The tool is for use with a single rope, a doubled rope or in a two line configuration.

An apparatus includes a frame and an access member. The frame is configured to be mounted to a structural support, and defines a first volume configured to receive at least a portion of a first insert, and a second volume configured to receive at least a portion of a second insert. The frame is configured such that when the first insert is within the first volume and the second insert is within the second volume a first engagement surface of the first insert is facing a second engagement surface of the second insert. The frame includes a first tapered surface that engages a tapered surface of the first insert to limit movement of the first insert along a lateral axis nonparallel to the longitudinal axis. The access member is configured to be coupled to the frame covering a portion of the first volume to limit movement of the first insert.

Disclosed is an anchor for rock or similar material, and methods therefor. The anchor has a hinged base, which base consists of at least a pair of pivotally connected wings, the wings able to pivot about at least one longitudinal axis between, a first position in a closed state and a second position in an open state, the open state having a dimension between opposing parts of each wing that is greater than when in the closed state. A locking mechanism locks the wings in either the first position, or the second position. A connecting portion adapted to enable a load to be connected to the anchor connects to the hinged base, the connecting portion having a loading axis which is substantially parallel to the longitudinal axis. The anchor can be set between either the first position, or the second position, and then anchored to enable a load to be connected thereto.

A climbing cam can include a stem forming the main body of the climbing cam. A moveable latch can be disposed on the stem and operable to tether the steam to a climbing harness of a climber. A spring-loaded cam lobe can be disposed on a first end of the stem. A trigger can be connected to the cam lobe so that the trigger is actuatable to retract the cam lobe from an expanded position to a retracted position and to open the moveable latch, allowing the stem to untether from the climbing harness when the cam lobe is in the retracted position.

A spring-loaded cam lobe can be disposed on a first end of the stem.

A removable anchoring device comprising a fixed first part with an expansion head, and a movable second control part having wedging half-rings and a gripping knob associated with a stop and a spring. The stop is arranged on the fixed first part and is movable with respect to the gripping knob by a relative translational movement to disable any release command in a predefined position. The gripping knob is thus able to occupy a first axial adjustment position offset from the stop to indicate the non-locked state enabling the release command, and is movable to a second axial adjustment position in engagement against the stop to indicate the locked state and to disable said release command.

A larger active camming device including a plurality of opposed camming lobes, a cam head, a retraction system, and a connection system. The cam head includes a stem end and two parallel axles coupled to the stem end. The retraction system is a unique system comprised of a trigger, flexible trigger wires, control horns, and torsion springs. The control horns couple the trigger to the camming lobes and are configured to reduce buckling and allow greater camming range. The retraction system can also include a retraction locking mechanism. The locking mechanism is used to store the cam in a retracted and locked position until it is needed by the climber. When needed, the climber can easily unlock and extend the camming lobes with one hand.

A camming clamping device comprises a head with a cam installed swivelling around a pivot shaft between retracted and extended positions. An annular end is mechanically coupled to the head. A rod of variable length connects the head with an annular end designed to receive a carabiner. A wire element made from textile material passes through the rod to connect the head and the annular end. A trigger is installed slidingly to selectively engage the retracted position of the cam. An adjustment device of the length of the rod defines at least a distance between the head and the annular end that is greater than a threshold distance to stretch the wire element and compress the rod in the first direction.
