Abstract

1283437 Counterweights POTAIN POCLAIN MATERIEL 20 April 1970 [22 April 1969] 18775/70 Heading B8B A device for fixing a counterweight 7 on the frame 1 of a load handling machine comprises a counterweight support 18 pivoted either to the frame at 17 or to the counterweight, and extending in its supporting position into a recess in the counterweight or frame respectively, whereby the counterweight may be supported in position prior to bolting it to the frame at 21, 22. The counterweight 7 is lowered into or lifted from its fixed position by a cable and pulley system including a pulley block 12 removably secured to the counterweight and a cable 14 removably backed at 16 to a port 5 of the frame 1, and passing over pulleys 8, 10 to a winch 2 of the machine. The centre of gravity of the support 18 is arranged relative to its pivot axis 17 such that it is stable in both its weight supporting position with its rear end engaging an abutment 1a on the frame, and its vertical position (dotted lines) when not supporting a counterweight.
