A safety fence for a vehicle testing device includes a fixed fence part, a slide fence part, a first angled fence part, and a second angled fence part. The fixed fence part is structured to be arranged substantially in parallel with a wheel of a test vehicle, wherein the test vehicle is placed on a roller exposed through a roller opening of a pit cover. The slide fence part is arranged in parallel with the fixed fence part, and structured to move in a longitudinal direction of the test vehicle. The first angled fence part is attached to an end portion of the fixed fence part, and structured to swing inwardly and outwardly of the fixed fence part. The second angled fence part is attached to an end portion of the slide fence part, and structured to swing inwardly and outwardly of the slide fence part.

A robot including: two link members with longitudinal axes that are coupled such that the link members are able to relatively rotate about an axial line; and a sensor that detects a force around the axial line acting between the link members due to an object pinched between the link members, in which the robot has such a shape that a width dimension in a direction along a plane of a cross-sectional surface of at least one of the link members, which perpendicularly intersects the axial line, on at least one sides from the longitudinal axes that intersect the axial line continuously spread from at least midway positions of the at least one of the link members in the direction of the longitudinal axes toward the axial line, respectively.

Disclosed are backhoe pedal guards for covering and protecting the foot pedals of heavy equipment machinery, including backhoes. The backhoe pedal guards are made of steel plate material, or other suitable material. They are configured for installation on or near the floorboard, partially enclosing and protecting the foot pedals, while allowing uninhibited access to the foot pedals by an operator. The backhoe pedal guards act as a safety device to prevent inadvertent engagement of a foot pedal, such as by dropping a tool onto the pedal. In an embodiment, a pair of backhoe pedal guards may be a unitary body connected by a front cross member.

A group lock box includes a box body and a door in which the door is shaped to have a recess that extends into an internal volume of the box body. The recess permits unique user locks that secure the door to the body to be partially received in the recess, which can make the locks not project as much from the outside of the box, thereby placing the locks closer to the center of gravity of the box. Among other things, this can make carrying the box with locks attached less unwieldy and can slim the overall profile of the group lock box with locks attached.

Aspects of the disclosure are directed to a safety adapter that is removably and replaceably securable to a hollow lock nut hydraulic cylinder that includes a threaded collar. The safety adapter may comprise a cylindrical sidewall having a distal axial end and proximate axial end, that at the distal axial end includes a top surface having a center through hole and at the proximate axial end includes a sidewall threaded surface on an interior surface of the cylindrical sidewall configured and arranged to engage with the threaded collar.
