Abstract: A workplace safety system includes an item of monitored equipment, a mobile communications device, and a scoring computing system. The item of monitored equipment includes a sensor, a transmitter, and a computing unit. The sensor is configured to generate signals. The computing unit is electrically coupled with each of the sensor and the transmitter. The mobile communications device is in wireless communication with the transmitter via a short-range communication protocol. The scoring computing system is in networked communication with the mobile communications device and is configured to receive data. The data includes an identity of an operator of the item of monitored equipment. A characteristic of operation is determined based upon the signals from the sensor and represents a manner by which the operator has used the item of monitored equipment. The scoring computing system is configured to generate a safety score associated with the operator. Methods are also provided.

Abstract: Discharge grates and grate components of reducing equipment have reduced amounts of material to provide lower costs, lower weight, and less scrap while still providing adequate resistance to bending, deflection, and/or warping and suitable material discharge.

Abstract: Shredder hammers having first and second major surfaces on opposing sides, and a circumferential edge. A mounting portion includes a mounting hole that extends from the first major surface to the second major surface, and is configured to receive a hammer mounting pin for mounting in a reducing system. The circumferential edge includes a primary impact face to initially impact materials to be reduced and a wear edge to subsequently crush and shear the material against a wall of the equipment. The hammer is biased forward on the pin to admit more material to be crushed between the wear edge and the grates.

Abstract: Shredder hammers having first and second major surfaces on opposing sides, and a circumferential edge. The hammer includes a mounting portion and a working portion. The mounting portion defines a mounting aperture that extends from the first major surface to the second major surface, and is configured to receive a hammer mounting pin. The working portion includes at least one recess in at least one of the first and second major surfaces with opposed walls that extend away from a distal portion of the circumferential edge. The hammers are used in shredding systems for shredding material.

Abstract: Shredder hammers include a hammer pin opening in which at least some portion of the interior surface is curved in a direction moving from one major surface of the shredder hammer to the other. This interior surface may be smoothly formed as an arc of a circle, as a parabola, as a hyperbola, or as another curved surface, with the local extrema within the interior of the hole (e.g., at or near the center). Providing the curved interior surface helps vary and disperse the locations where force is absorbed due to contact between the hammer pin and the walls defining the hammer pin opening when the shredding hammer blade contacts the material to be shredded. Other structures include engagement between the hammer pin and the hammer as part of a bushing member, a spool or sleeve member, or a ball swivel member.
