Height adjustment mechanism for an auxiliary member on a crane

A lift crane includes a carbody and movable ground engaging members mounted on the carbody. A rotating bed is rotatably connected to the carbody and includes a counterweight support frame including a rack coupled directly to a lower surface of the rotating bed. A boom is pivotally mounted to the rotating bed. A counterweight unit movement device is configured to move the counterweight unit toward and away from the boom. At least one auxiliary member includes a counterweight pad that is configured to not touch the ground during a pick, move, and set operation. A linear actuator is configured to adjust a distance that the counterweight pad is above the ground.

Retention assembly for a conduit on a crane

A retention assembly to support and couple a conduit to a mounting bracket on a crane includes at least one mounting bracket and at least one conduit with at least one end with a connection fitting. A plug is removably coupled to the connection fitting. The plug includes a first end and a second end spaced apart from the first end. The plug also includes a stud having a first end and a second end spaced apart from the first end, and a longitudinal axis extending between the first end of the stud and the second end of the stud. The second end of the stud is configured to extend away from the first end of the plug. A retainer is configured to couple with the stud to retain the conduit proximate the at least one mounting bracket.

Sponge mop with scrubber attachment

ABSTRACT A scrubber attachment for being fixedly mounted to a wringer type sponge mop without the necessity for any extra, attaching hardware. The scrubber attachment carries a scrubber pad and is fixedly secured to the mop head at a predetermined angle. This combination yields a mop capable of both conventional sponge cleaning and of abrasively rubbing to effect further cleansing treatment of a surface without the risk of moving the scrubber out of operative position during use.
