Abstract: An improved radio-controlled spreader for handling cargo containers is disclosed having a number of improved safety features. A switching circuit, including proximity switches mounted on the respective corners of the spreader for sensing contact with the cargo container, controls the locking and unlocking circuits for twist locks which engage the container. The switching circuit prevents premature locking and accidental unlocking. The expansion and retraction circuit for the spreader includes swtiching means for controlling the flow of hydraulic fluid to the spreader in its expanded position which in cooperation with the hydraulic circuit prevent damage from external forces applied to the spreader ends.

Abstract: A pin-off and door closure assembly for a stationary refuse compactor which includes a packer unit having a ram for forcing refuse into a portable container through a load opening in the door thereof, the container being removably attached to the packer unit. The pin-off portion of the assembly includes an elongated pipe which, when not in use, is stored in a refuse-free compartment on the face of the ram. The pin-off pipe is transferred to its position of use across the container door load opening by extension of the ram into the container, following which pins are inserted through both sides of the container into the ends of the pipe for securing the latter into position. A hinged flap forming the forward side of the storage compartment permits the pipe to be removed from the compartment upon retraction of the ram.

Abstract: The invention concerns a method for assembling two shaped sections (1, 2) at intersecting directions. This method consists in engaging one of the shaped sections, 2, into a slot fashioned in the other 1, and in locking the latter using cotters 3 comprising a rod with a thinned segment on part of its periphery; each cotter is introduced by simple sliding action in a hole with its thinned part in contact with the shaped section 2 and then is made to pivot to ensure the locking.The invention is applicable in particular to the housing and construction industries to assemble balustrade or stairway uprights and rails.
