Whether it’s India’s first 2 car Pit jack system back in 2003 to Delhi Metro Rail Corporation or again a first 6 car Pit jack system in 2009 to DMRC, Columbus McKinnon continues to lead the aspect of safety and innovation in Indian Metro and Rail segment. Leading the market innovation as always, Columbus McKinnon, through its brands- Pfaff Silberblau and STAHL CraneSystems India, delivered and executed the Vande Bharat project successfully.
This is one of its kind 8-Car Pit jack system globally, which, unlike standard pit jack system, boasts of several modifications including body stands with swivel head design for the DTC coaches and enlarged body stands with switching plate design. These design modifications were necessitated followed by the observation of several Dimensional variations across the train length. However, despite the challenges the system was designed to mitigate the dimensional variation between DTC & NDTC coaches as well varying jack pad location across the train length.
The system is designed to handle a train length of up to 200 Mtr and a weight of staggering 464 Tons. The system is synchronized using a fail-safe PLC that does control, interlock function and monitoring of the jacks in a range of ± 5 mm, which allows simple user interface and provision of modification/expansion in future control.
The control mechanism of the system is designed through two main controls incorporating the fail-safe PLC unit and a local control in each pit incorporating corresponding local PLC module to monitor, execute and operate the group mode as well as individual mode of the system effectively and safely. This gives flexibility to the user regarding the operation, where either of the two main control panel can be made into master while the other one serves as the confirmation panel.
The system consisting of bogie lifting unit for static and dynamic load and a body stand unit for the static load. The screws of the lifting unit at both, bogie lifter and body stand are supported by spherical roller bearings in order to avoid tension force on the screw. This is crucial to ensure both, to avoid breakdown and a longer life of the system. A solid bronze carrying nut and safety nut ensure that screws are held together safely for the operation.
While the bogie lifter unit is designed to lift to a maximum height of 1.8 mtr, body stand can lift upto 2.7 mtr. The system is run using two equally rated motors and is designed for redundancy in such a way that even in case of a motor failure, another motor can lower the system safely back on the tracks.
Commissioned in 2024, the system is a landmark installation for India’s growing metro and rail market. Through its brands Pfaff-Silberblau and STAHL CraneSystems India, Columbus McKinnon is committed to serve the Indian Metro and Rail market through technology transfer and local investments under Make in India policy.
