Industry Value Chain
Wind turbines have come a long way since their inception, from their earlier use of pumping water to their current application of generating massive amounts of electricity. But while their details get complicated, but their overall design concept is basic.
The energy produced by a wind turbine is proportional to the size of the blades mounted around the rotor. The longer the blades, the higher the power output. More powerful turbines with longer blades require the construction of higher and stronger wind towers that can be deployed onshore and offshore. Thus, the accurate construction of wind turbine towers is critical to ensuring longevity of these expensive devices.
Himalaya enjoys a significant respect and credibility when it comes to rolling equipment needed to build wind towers. Through 40+ years of experience and expertise of building plate rolling machines, we have developed specific solutions for production of wind towers.
Why Himalaya?
Himalaya plate bending machines assure high productivity and extreme precision. Our machines are built to deliver quality rolling and pre-bending of the plates.
Himalaya machines have a robust steel structure made from heavy metal plates, connected to each other by a strong box design chassis with interlocking frames & strengthening ribs. These allow for parallelism of all axes and precise surfaces, as well as longevity and precision.
We design the rolls with optimal diameter and use forged carbon steel rolls machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. Our rolls are also crowned to compensate for roll deflection during the bending process.
Our machines are equipped with a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled. Twin speed operation also reduces the energy consumption up to 50% at slower speeds.
Himalaya Planetary driving system used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions.
The simple yet robust design of our machines also enables ease of operations and faster manufacturing. And our full package of accessories provides quick movement of rolled plates for rolling, welding, and subsequent manufacturing activities. The high construction quality of our machines means that they can work 24 hours a day and are highly reliable with minimum downtime.

The HIMALAYA Advantage

-
What is done to compensate for deflection of rolls during pre-bending and rolling?All rolls are crowned (cambering) for compensating deflection.
-
What is the arrangement provided for balancing of top roll when swing arm is opened?Top roll is counter balanced automatically once the drop end is opened without any jacks or manual arrangement.
-
Is there any method to know the position of bottom rolls?DRO (Digital Readout) is housed on the operating console which gives the position of the bottom rolls with respect to the top roll.
-
What is the capacity for cone bending?Cones can be bent up to the edge-bending capacity of the machine. The bottom rolls can be inclined for the required cone angle.
-
What is the level of protection for electrical components?Some of the electrical bough outs are IP 55 like motors, switchgears etc. The electrical cabinet will be manufactured as per our standard practices and will meet IP 55 protection.
-
Is the main drive reversible?Forward and reverse to the main drive is provided. The bottom rolls can be moved up and down individually.
-
What is the type of oil required?Hydraulic oil – Enklo 68 Planetary Gear box – EP 90
-
Where are the main machine controls?Operating console houses push buttons for all the operations of the machine. The console is movable so that the operator can keep it at any desired location.
-
Can we bend hot plates on the machine to get higher thickness capacity?Although the standard machine is not meant for hot rolling, occasional hot rolling can be done (a few jobs per month) provided that suitable precautions are taken.
-
Some plates have high yield point (YP). The rolling capacities are rated for 26Kg/mm2. How to find the equivalent thickness?Divide the Actual YP by 26. Find square root of this number. Multiply this value by actual plate thickness to get effective thickness.
Enjoy the peace of mind that you are in good hands.
