Abstract: An arborist block is provided that includes a front plate having a front plate inner surface, a back plate having a back plate inner surface, a sheave rotatably coupled to a sheave axle secured between the front plate and back plate and radially centered along a sheave rotational axis, and a plurality of sheave locks situated in sheave lock tracks and radially extendable into a plurality of lock receiving recesses in the sheave to prevent rotation of the sheave relative to the sheave axle.

Abstract: A securement device is disclosed to aid in the movement or suspension of equipment or people through the air or along inclined surfaces using rope, cable, wire, or similar component and associated lifting, winching, lowering devices, mechanical advantage systems or manual power by retaining a system component between a yoke and a load pin using a load pin assembly. The load pin is biased into a locked position through the use of a biasing member but may be moved from a locked position to a retracted position by journaling a lock pin through a lock slot. Some embodiments restrict movement of the load pin using a track pin and a track slot, while other embodiments use the interaction of a lock ring and a keyed recess formed in the yoke. The securement device may be incorporated as part of a rigging plate.

Abstract: A high load descender for rope access and rescue has a ratcheting sheave mounted to a pivoting arm, which translate with rope tension against a fixed shoe. The ratcheting sheave has a groove that grips rope during descent while allowing free rotation for ascent and progress capture. An adaptive release linkage enhances ease of operation and control while maintaining convenient handle position in a variety of conditions.

Abstract: An improved top down furling system includes one or more improved components. A lower rotary drive unit with a rotary tack swivel rotates against a fixed portion of the furler, or is configured to permit routing of the tack line below the unit. The system may include an anti-torsion cable constructed in a manner so as to be able to transmit torque without excessive tension applied to the cable. The system also may include an end terminal of the anti-torsion cable having a quick side mount or bayonet type connection to the rotary drive unit.

Abstract: A fabric rolling system includes a driven roller attached to a fabric. The roller is sufficiently strong and supported so as to bear increasing loads as the fabric is rolled. A fabric deployment device can also be included.

Abstract: Hydraulic pump applications sometimes require the pump to be able to provide relatively low pressure with larger amounts of fluid moved, while other applications call for relatively higher pressures but less fluid moved. The multi-speed hydraulic pump can operate at multiple speeds so as to provide multiple outputs of pressure and flow. In a two-mode version, the pump has one mode of operation that provides for lower pressure/more fluid moved and another mode of operation that provides for higher pressure/less fluid moved. Having multiple modes of operation in the pump allows for a single pump to provide greater movement or greater pressure while working within the limits of the force or speed at which the pump is actuated.
