The upper unit may have a retainer portion and two legs extending from the portion. The lower unit may have a retainer portion and two legs extending from the portion. The upper portion may at least partially overlap the lower portion.

Abstract: A floor structure system may have a hub with a plate with an upper surface. A beam connector may be connected to the upper surface. At least one pin may extend from the upper surface. The pin may be adapted to connect with a rod or a cable extending generally transverse the pin direction. The rod or cable may have an aperture adapted to receive the at least one pin. The system may also have a beam attached to the beam connector.

Abstract: A system for connecting trailer towing components may have a pin having a first leg and a second leg. The system may also have a torsion bar having a first set of splines, and a main beam for a trailer. The main beam may have an insert adapted to selectively receive the torsion bar therein. The main beam may also have at least one guide aperture adapted to selectively receive one of the pin legs. The system may also have a secondary beam adapted to be selectively located at least partially within the main beam. The secondary beam may have apertures adapted to receive at least one of the legs of the pin and the torsion bar.

Abstract: A scaffold rack may have a first side and a second side. An upright portion may be located between the two sides. The first side may have at least one pair of scaffold frame tubes adapted to selectively secure at least scaffold frame. The second side may have a first arm adapted to selectively support at least one walkboard thereon and a second arm adapted to selectively support at least one scaffold bracket thereon.

Abstract: A scaffold apparatus may have a saddle with a platform and two spaced apart parallel sides extending above the platform. The apparatus may also have a beam having a beam flange attached to an end portion of the beam. The apparatus may also have an upright connector with a bottom portion, where bottom portion may have an insert, and a plate attached to the bottom portion.

Abstract: A lubricant composition comprising an alkylated naphthalene component and a mineral oil component and which is essentially free of ammonia reactive components is described. In certain examples, the lubricant composition is food grade. The lubricant compositions are particularly well suited for use in ammonia refrigeration compressors and ammonia refrigerant transfer pumps. The mineral oil has no more than about 60 percent of paraffinic compounds by weight of the mineral oil. When used to lubricate ammonia refrigeration compressors, the lubricant composition has an ISO VG of 46 to 100. When used to lubricate ammonia refrigerant transfer pumps, the lubricant composition has an ISO VG of 22 to 46.

Abstract: Embodiments of the invention provide a food grade cleaning oil, such as one of synthetic or mineral oil origin, which can be used for the cleaning, flushing, and lubrication of compressors and vacuum pumps. The cleaner composition can include alkylated aromatics, such as naphthalenes. The cleaner composition can be compounded with additives including one or more of antioxidants, corrosion inhibitors, antiwear additives, metal passivators, and anti foam agents that are cleared for incidental food contact.

Abstract: Embodiments of the invention provide a food grade food grade lubricant, such as one of synthetic or mineral oil origin, which can be used for the lubrication of compressors and vacuum pumps. The lubricant composition can include a blend of alkylated aromatics, such as naphthalenes, and synthetic hydrocarbons comprised of polyalphaolefin fluids. The blend can be compounded with additives including one or more of antioxidants, corrosion inhibitors, antiwear additives, metal passivators, and anti foam agents that are cleared for incidental food contact.

Abstract: A trailer having retractable wheels. A lock-out mechanism is provided that prevents the trailer from being connected to a vehicle when the wheels are in the retracted position. The lock-out mechanism may also be configured to prevent movement of the wheels to the retracted position when the trailer is connected to a vehicle.

Abstract: A replaceable locking and securing device for securing a first member to a second member includes a replaceable bracket, a lock and a fastener. The bracket defines one opening when the bracket is operatively connected to the first member.

Abstract: A self locking basket assembly has a basket extending from a base platform, and a gate system for releaseably securing a worker within the cage. The gate system includes a gate operatively mounted on a pivotable locking mechanism. The locking mechanism is opened by moving the gate in a rearward direction at an angle to a plane defined by the base platform and thereafter pivoting the gate about a hinge mechanism to an open position.

Abstract: A stabilizing system includes at least one outrigger assembly. Each outrigger assembly has a pivotable first leg operably connected to a second leg. At least one locking mechanism is operatively mounted to the pivotable first leg and the second leg. At least one sensing mechanism is connected to the first leg for detecting when the first and second legs are in a stabilized position.
