Hoist & Winch elevates success of large construction project
Hoist & Winch Ltd has recently completed a challenging project for one of the UK’s biggest construction companies involved in large-scale new home development projects. Faced with a demanding and highly technical brief, Hoist & Winch rose to the task, providing a turnkey lifting system solution to ensure complete success for its client. The requirement was to install a concrete ceiling mounted 7.5t swl (safe working load) lifting beam and manual chain hoist into the basement energy room of a large new tower block. This development is part of a large-scale prestigious regeneration project providing 5500 sustainable new homes in North London. At the design stage, following formal tender and contract award, Hoist & Winch set about identifying the optimal solution. Due to restricted access into the basement area, the company decided to utilise a two-piece lifting beam design with an overall length of 7m. To join the two lifting beam sections, Hoist & Winch designed a central splice joint of bolted construction with a reinforced bottom beam flange. In order to spread the lifting loads over a greater area of the concrete ceiling slab it was decided to mount the lifting beam via four intermediate cross members, each having a four-bolt/anchor fix into the concrete ceiling at both ends. Featuring a robust bolted construction design it was possible to deliver the lifting beam to site in fully dismantled form for ease of transportation and access. M24 resin anchors with an embedment of 255 mm into the 400 mm deep reinforced concrete slab fixed the intermediate cross members directly to the ceiling for maximum security. For approval by engineers at the main contractor, Hoist & Winch submitted design drawings and calculations for the structural design of the lifting beam and loading of the resin-type ceiling anchors. With the design approved, […]
