A detailed case study was recently carried out by Mr. Rajesh Kanna, Product Head – AWP at Gemini Power Hydraulics (Haulotte dealer) for one of its important clients in the manufacturing sector who has different requirements due to various plants and applications.
Mentioned here are the plants and applications for which Mr. Kanna needs a suitable platform which should be one for all.
Pre Silication Plant – Phase 1, 2 & 3Application: Maintenance of Pipes & Flanges, Painting, Repairing, Rework.
Requirement: All the pipes are located at a height between 18 – 20 meters and access is clear. Even a 20 meters Machine will be enough to cover all the equipment.
Post Silication Plant – 4th PhaseApplication: Accessing flanges located above 20m height and at an outreach.
Requirement: In Post silication plant, the Drum Height is 18.6 meters, and customers' need is to require access above that. The minimum height required is around 22 -24 meters. Also it is to be noted that the Boom lift cannot be positioned near the working area, since the access is very less. Hence, the customer shall require a boom lift with working height not less than 25 meters.
Bauxite Handling AreaApplication: Changing of Idlers of Belt conveyors
Requirement: The Peak point of Conveyor will be around 25 - 27 meters, but the Boom Lift is required to be positioned on road. Considering this aspect, the customer may require a machine more than 30 meters working height.
Calcination PlantApplication: Expansion bellow maintenance (EFP Outlet) located @25 Meters from Ground Level & 15 Meters inside from the machine parking area on the road.
Requirement: Up & Over clearance required will be more than 11 meters to clear the pipelines from the road to reach the Expansion bellow and other areas, which are located at a height of 25 meters. Horizontal outreach should be more than 15 meters as the machine can be parked only on the road, whereas the expansion bellow located at a distance 12-15 Meters inside. The three sides of bellow can be accessed easily which are marked in yellow. However the access to the forth side (not visible in the picture) shall be limited.
Requirement: All the pipes were located between 20 - 24 meters only. But in some places like mentioned in photograph, the machine can't be parked near the pipes and hence the customer will need a machine with at least 30 meters with a working height to reach all areas.
What is Up & Over clearance and Horizontal out Reach of a Boom lift?Up & Over Clearance: The height required to clear the hindrances (like pipes, columns etc.) and above that we can get clear access as the horizontal booms will not touch the hindrances.
Hence the customer requires more than 11m for the expansion bellow application.
Horizontal Out Reach: The maximum horizontal distance which can be covered when the Horizontal Boom is extended fully. The customer will need 15 – 17 meters outreach to access the Expansion bellow Application, 8-10 meters for Post silication application and 10 -12 meters for the Evaporation plant application.
Considering all the above applications in various plants, Haulotte recom- mends to its client, HAULOTTE HA32PX (31.8 Meters working Height), which have 11.35 Meters Up & Over clearance and 21.3 Meters Horizontal out reach.
Critical Dimensions required to cover all plant applications:
- Articulated Boom lift with Not less than 30 Meters working Height
- Articulated Jib (To get better access, To go above and come down by 1-2 Meters)
- 4 wheel drive & 4 Wheel steering (As it is Hill Area & Lot of slopes are there)
- Minimum 18 Meters Out Reach (To reach the expansion bellow)
- Minimum 11 meters UP & Over Clearance to avoid the Hindrance pipe at 11 Meters.
Hence, HAULOTTE HA32PX is the best solution offered by the company to its client as it is perfectly suitable for all the above mentioned applications.
