Chain hoists

The incident began during a normal mn when the operator noted an electrical short not long after the start of the melt. Standard shutdown procedures were initiated, and the titanium electrode was retracted at a rate of about 30 cm/min using a chain hoist. During shutdown, what proved later to be a water leak into the cmcible occurred with a concomitant pressure rise. Three mpture discs failed at about 4 bar. Some 2 min... 

Lifting Chain hoist Chain operated geared hoist for manual load handling capability. Standard lift heights 8 to 12 It (2.4 to 3.7m). 25 (23)... 

Double chain hoist should be provided and regularly maintained. 

Air chain hoists are available operated hy air motors driven hy compressed air at either 4 or 6.3 hars. Safe working loads range from 0.25 to 50 tonnes. These may also he linked to airdriven trolleys v 4iere hoists are used in conjunction with an overhead gantry. 

The chain hoist is intended to lower or raise the carriage and package in the guide tube. The assembly is similar to a small crane, with a chain being paid out or withdrawn over the guide tube. The amount of chain paid out is monitored and can be related to the interlocks and overall sequence control. 

Floor plates were then fitted around the adaptor in order to provide a continuous floor capable of carrying the ton load imposed by the Cable Iteel and Chain Hoist Assemblies.

The continuous spindles on which the hammers are mounted are extracted and refitted with hydraulic devices. An electric chain hoist can be introduced through an access door in the upper casing into the interior. In this way each hammer to be dismantled can be lifted out of the crushing chamber.
