By Haili Zhu

Generally, the high lift capacity electric hoist is used on double girder overhead crane or gantry crane. However, the following case from DQCRANES, the  Chinese material handling expert, is very special. In order to give you some inspiration or idea to your material handling solution, DQCRANES is here to share with you who has the similar working conditions and lifting requirements with the Philippine client.szVHenan Dongqi Machinery Co., Ltd

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. Client wants the lift height to be 30m, the drum weight be about 50ton, length be around 14m and however the lifting drum needs not to move too much.szVHenan Dongqi Machinery Co., Ltd

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.szVHenan Dongqi Machinery Co., Ltd

DQCRANES engineer calculated and adpoted the H-beam: H800xW300mm, considering the bearing, bottom plate is 40mm thickness, much thicker than the top plate 26mm.szVHenan 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:szVHenan Dongqi Machinery Co., Ltd

The hoist length is more than 4m, the H beam is only 5m, so it moves a very little space. , which is suitable for required working condition. The finished product seems very big, everything is big, wire drum, hook, pulley, motors.szVHenan Dongqi Machinery Co., Ltd
