Client Requirements:
- This client is one of DQCRANES’ regular clients, from the M&J Fabrication & Installation company in Philippines. 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, and length be around 14m and however the lifting drum needs not to move too much.
Hoist 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.
- DQCRANES crane machine engineer calculated and adopted the H-beam: H800xW300mm, considering the bearing, bottom plate is 40mm thickness, much thicker than the top plate 26mm.
- DQCRANES settles down to use two 45T hoist electric crane to lift the drum. Two 30T hoists are enough on theory, but considering safety, client prefers to use two 45T hoist electric crane.
- 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 electric crane hoist seems very big, everything is big, wire drum, hook, pulley, motors.
