Clinker silo steel structure – Case Study
Clinker silo steel structure – Case Study
Project scope: Equipment used: Load details:
|
Project execution:
A 650t crane was rigged up and lifted the ring beam assembly above the silo. Stay cables were used to secure the ring beam at 44m. Two 250t cranes are used to connect the rafter assembly (25t each). Once the rafters have been assembled, the silo’s load is gradually released.
The entire penthouse set (150t) of dimensions (15m x 15m x 22m) is lifted and placed on top of the ring beam with a rafter.
As per the scope we initially lifted the 40m long conveyor in tandem with 450t and 250t cranes and erected it over the existing column and silo.
Challenges of the project:
- The main crane had to hold the ring beam above the silo for 15 days. During these days, the rafters and purlins were installed, increasing the load from 70t to 135 tons.
- The rigging arrangement of the penthouse assembly was designed to lift the load with minimal stress on the steel structure. Detailed load analysis was done, and counterweights were added to the structure to ensure the COG of the load remained at the centre of the structure.
- Since the site is near a mountain, the wind speed created a tunnel effect, and the load surface area is also large, we had to calculate the permissible wind speed.
- To complete the project, a complex rigging system was created.

Project execution: A crane has been rigged up and lifted the ring beam assembly above the silo. The ring beam was secured with stay cables at 44m. Then with the help of 2 x 250t cranes, the rafter assembly (25t each) is connected. The silo’s load is gradually released once the complete rafters have been assembled. After the ring beam is erected with a rafter, the entire penthouse set (150t) of dimensions (15m x 15m x 22m) is lifted and placed on top. As per the scope we initially lifted the 40m long conveyor in tandem with 450t and 250t cranes and erected it over the existing column and silo.

- The rigging arrangement of the penthouse assembly was designed to lift the load with minimal stress on the steel structure detailed load analysis was done, and counterweights were added to the structure to ensure the COG of the load remained at the centre of the structure.
- As the site was near to maintain the wind speed was high which created a tunnel effect and the load surface area is also high, we had to calculate the permissible wind speed to mitigate the tunnel effect.

Al Faris recently installed a Steam Box at a new Waste to Energy Plant in Dubai
Al Faris recently installed a Steam Box at a new Waste to Energy Plant in Dubai.
Due to Industry reputation and expertise involving high complexity in planning and execution, Al Faris were
recently awarded this project.
This challenging installation was done at a height of 2.8m using our specialized in-house modular towers
and other skidding equipment.
The Steam Box was delivered in two parts, the bottom part weighing 27t and the top part weighing 40t.
The top part was tandem lifted for top and tail operation using our 250t and 200t mobile cranes. It was
then placed onto skid tracks and skidded into a temporary position. Thereafter the bottom part was placed
on the skid tracks. The top part was then lifted in order to allow the bottom to be skidded underneath. Once
the bottom part was skidded into final position, the top part was lowered onto the bottom part and both
parts of the Steam Box were joined together for final installation.
Challenges:
The clearance while skidding was only 30mm. All measurements and markings were done precisely during
the operation.
The COG of the top part of the steam box was away from both the lifting points during the lifting of the load
from the trailer which could have caused the load to slide. In order to avoid this situation, we made a
temporary packing arrangement of stools at the corner of the steam box.
A project of this nature requires exceptionally detailed planning to orchestrate the complex activities
necessary for ensuring uninterrupted safe services; from detailed planning to ensuring utmost safety
during all lifts. The technical support documentation, execution plans and HSE protocols were prepared
in-house and discussed with the client prior to project execution.
Al Faris Group along with our partners Fabtech International relocate structures that are the biggest of its kind in the mining world.
Al Faris Group along with our partners Fabtech International relocate structures that are the biggest of its kind in the mining world.
Al Faris along with our partners Fabtech International, successfully completed the loading, transporting and assembling of mining machines (bucket wheel stacker reclaimer & ship loader) at Jebel Ali Port for Thyssenkrupp.
We recently relocated the entire loads (2100t and 1650t each) 150m, using our 96 axle SPMT’s.
These are massive structures and the biggest of its kind in the mining world.

Al Faris Group executed the complete logistics chain for 30 overflow tanks at Dubai Solar Park!
Al Faris Group has executed the complete logistics chain including receiving, storing, transporting and lifting of 30 overflow tanks which are part of the ongoing Mohammed Bin Rashid Al Maktoum Solar Park project, the largest single-site solar park in the world!
Due to Industry reputation and expertise in transporting large, abnormal loads involving high complexity in planning and execution, Al Faris were recently awarded this project.
Each tank was 52m long and weighed 235t which made it an extremely big challenge for byroad transportation. The biggest challenge was to find a feasible route from Jebel Ali Port to Solar park, Al Qudra in order to transport the cargo efficiently.
The transportation was carried out with our Mercedes Arocs trucks attached to 2 files 30 axle Goldhofer THP/SL conventional hydraulic trailers with 2 tanks in one convoy. At the project site, the overflow tanks were lifted using our Liebherr 400t crawler crane along with other supporting mobile cranes which travelled a distance of more than 100m before placing the load on the foundation.
A project of this nature requires exceptionally detailed planning to orchestrate the complex activities necessary for ensuring uninterrupted safe services; from route analysis to on-road safety permissions. The route was analyzed and surveyed by our technical team. The technical support documentation, execution plans, route analysis report and HSE protocols were prepared in-house and discussed with the client prior to project execution.
