GJJ / EEE spends a major percentage of its revenue on R&D for constant technological improvements, with the highest safety standards. We have standardized all our Masts, Wall Ties, Base Frames, Trolleys, and Self-Erecting Winches to be fully galvanized, thus making them last for ~25 years with low maintenance.

GJJ / EEE provides ST52 grade Mast structure for the Men & Material Hoist.
We believe that the Mast structure is the most crucial component which ensures the stability of the hoist and should be very strong to take the entire load of the hoist along with the full load, huge reaction forces with the wind velocity and seismic conditions.
The ST52 grade steel for the mast structure has the highest and optimum tensile strength to withstand any type of loads on the hoist (Lateral or Static vertical), which is acceptable across all the 5 continents.
Our masts provide the high reliability, enabling the same mast section to be used even up to the heights of 500 m with negligible vibration & increased wall tie distances of 9~10m instead of 6m. We have standardized the galvanized 650x650x1508 mm masts for a long life, rust-free structure, thereby improving equipment life up to 25 years; this is desired by any contractor and thus the high resale value of our hoist.
After extensive simulations of varied specifications and manufacturers, our R&D configured a customized mechanism through OEMs for their Geared Motor from SEW Germany and NORD Germany, and VFD from Siemens Germany.
This combination enables huge power savings of up to 35~40% in a year. At Indian construction sites that are now moving towards faster pace of production and using multiple hoists on a site, this power savings grows multi-fold. For example, a 2-ton single cage hoist with just 22kW motor achieves speed of 46 m/min with full 2-ton load, saving about Rs. 4 to 5 lakhs worth of electricity per hoist, per year.
Our hoist proved this at Raymond in Thane, Mumbai, with energy meters fitted on it. Today, Raymond is using 13 hoists of GJJ / EEE.
Schmersal Germany offers the best limit switches which have a lifetime that is at least five times higher than that of any other brand.
In spite of the higher initial costing, our R&D department decided to opt for Schmersal Germany owing to the long-term savings in terms of negligible breakdowns. What we achieved was value for money and unmatched performance, along with reliability for the next 20~25 years.
