Client Requirements

This case is from a Philippine client, M&J Fabrication & Installation company, which is one of DQCRANES’ regular clients This time they need DQCRANES to provide a material handling solution to their boiler project in Philippines. The Philippine client wants to lift a boiler steam drum from ground to the ceiling beam, which is a double truss beams. And the distance between truss beam is only 5m width.

Solution

In order to lift the drum stably, the ideal idea is to overlap two H-beam on both sides of the truss beams, with two electric hoists hanging under two H-beams. The lifting hook together with the lifting belt takes drum bottom and lifts it up. During the whole lifting process, the H-beam is very important to support the hoist and load weight.TRaHenan Dongqi Machinery Co., Ltd

DQCRANES settles down to use two 45Telectric hoists to lift the drum. Two 30T hoists are enough on theory, but considering safety, client prefers to use two 45T electric hoists. The electric hoist drawing is like this:TRaHenan Dongqi Machinery Co., Ltd
