Title: (EN) Work load lifting system for a vertical vacuum furnace
Abstract: front page image
(EN)

A lifting apparatus for a vertical vacuum furnace is disclosed. The apparatus includes first and second support modules arranged in spaced parallel alignment and first and second reversible lifting mechanisms mounted on respective ones of the first and second support modules. The apparatus also includes first and second motive means coupled to the first and second reversible lifting mechanisms for driving the reversible lifting mechanisms. First and second trolleys are operatively connected to the first and second reversible lifting mechanisms and adapted for engaging with a payload. The apparatus further includes a control system connected to the first and second motive means for controlling the operation of the first and second reversible lifting mechanisms whereby the first and second trolleys can be raised or lowered. A vertical vacuum furnace assembly including the lifting apparatus is also disclosed as well as a support module and a bottom head assembly for the lifting apparatus.
