Advantages of elevator consoles using bolted connection;
Errors resulting from incorrect manufacturing can be returned to the elevator console without damaging the material integrity.
The bolt-nut pair is subjected to shear stress under load. Bolts are standard manufacturing and their strength according to quality class is as follows.
Bolt Strength Classes
3.6 4.6 4.8 5.6 5.8 6.6 6.8 6.9 8.8 10.9 12.9 12.9 14.9
Here, the first digit represents 1/100 of the bolt material's breaking strength in N/mm2. 1/10 of the product of the two figures represents the yield strength of the bolt material in N/mm2.
It is an economical solution
The use of standard fasteners simplifies the engineering calculations of elevator consoles, but also provides economical solutions as their production is based on "mass production".
No additional action required
The bolted connection does not create additional stresses and distortions in the material from which the elevator console is produced. It does not weaken the material and does not require additional processing.
It is fast and practical
A worn bolt can be easily replaced, the entire elevator console need not be replaced.
A strength class is superior under load
The bolted connection does not react unexpectedly under load. Sufficient strength can be achieved with the right choice.
It is safer in the event of an earthquake
In the event of an earthquake, the bolted weight sections will meet the impact without breaking, with shifting and ductile ruptures in the slot axis permissible, rather than sudden breaks such as welding.
CONCLUSION:
Welded consoles, which are presented as “cheap elevator consoles” in the market, actually cost much more when compared to EMA Elevator Consoles systems.
In welded and cheap consoles, assembly takes a long time and time is wasted. It means a waste of time; means longer hours of master work and later delivery. So it's also a waste of money...
In EMA Elevator Console systems, you can make perfect assembly in the shortest time due to its flexible measurement capability and bolted structure.
The second cause is that extra dowels, bolts, and nuts are utilized in inexpensive elevator consoles, and the extra materials are discarded after installation. One carton of the product is utilized in the EMA Elevator Console systems for each floor. There isn't too much or too little product when the assembly begins. Weight brackets, main rail brackets, dowels, bolts, nuts, and nails are all present in a package of EMA console sets. In other words, you design your plans knowing how many elevator consoles you will provide to the working masters and how much work will be accomplished with these consoles.
