APPARATUS FOR FACILITATING NEW CONSTRUCTION AND THE INTERNAL INSPECTION AND REPAIR OF LARGE VESSELS, SUCH AS RECOVERY BOILERS AND TANKS

摘要

An apparatus for new construction as well as internal inspection and repair of large vessels (1), such as recovery boilers and tanks, comprises a platform (10) which is vertically adjustably suspended by means of suspension cords (13) hanging down from a roof (6) of the vessel (1). The platform (10) is built from at least two parallel spaced-apart girders (11), to which the suspension cords (13) are attached, and at least one plank (12) is arranged perpendicular to the girders (11) and interconnecting the same, the plank resting on the girders (11) and at least partly covering the same. The girders (11) are individually vertically adjustable first lattice girders, which have flat upper sides forming a footboard, on which it is possible to walk and operate safely. The plank (12), on which it is also possible both to walk and work, has a certain overlength, which allows the girders (11) to be individually movable in the vertical direction and sideways within certain limits, thereby significantly increasing the applicability of the platform (10). ® KIPO & WIPO 2007
