Project challenges
The Sohar plant of L&T was using 2 nos. of 200/50t DG EOT cranes in one of its manufacturing bays for handling heavy components and fabricated structures. They wanted to relocate these cranes from the Sohar plant to their manufacturing facility at Hazira in India. The Hazira plant is one of the largest heavy engineering plants in the world where cranes of various manufacturers including ElectroMech are being used.
The relocation of these cranes from the Sohar to Hazira plant was planned to further boost the handling capacity of Hazira plant to meet growing production requirements. The entire project was challenging for several reasons such as
- The two cranes, each with a capacity of 200/50t and span of 23.6m, are extremely heavy, being of old design
- Each crane with around 25m long girders weighs about 25t
- Both the cranes had been installed at 25m height and taking them down was indeed a challenge
- The entire crane dismantling was to be completed in just 15 days, that too, without affecting regular production in the plant
- The cranes were to be re-erected safely and commissioned at the Hazira plant in India
Solution from Cranedge
Considering the mammoth size and weight of each crane, the L&T team was anxious about the feasibility of taking down the cranes safely without halting their regular work in the same plant.
However, the Cranedge team, with its expertise of providing solutions for such critical challenges, suggested an easy way out. The idea of temporarily opening the roof was put forth by the Cranedge team. This would allow a crawler crane to handle large and heavy parts from outside just by lowering the hook from the opened roof without actually entering the shop floor.
With this idea, the Cranedge team developed a complete project schedule to meet the deadline stipulated by L&T.
The job was well done at Oman with proper packing and marking of components so as to make the re-erection easier. L&T undertook the responsibility of shipping the crane to the Hazira plant.
Once it reached there, the Cranedge team re-erected the crane and commissioned it, within just 15 days.
The L&T team is extremely happy with Cranedge’s professional work and for completing the project well before the deadlines, while adhering to the highest safety standards.
The work of dismantling the cranes in Oman was handled through our associate company in Dubai – ElectroMech FZE. The erection & commissioning in the Hazira plant was handled by the Cranedge team in India.
