Customer- and application-specific solution for bogie and wheelset handling
A bogie consists of a frame to which other parts such as wheelsets and springs are attached. They all carry the entire weight of the vehicle at high speeds and at the same time guide the rail vehicle on the track.
The reconditioning and maintenance of wheelsets and bogies is therefore essential for the maintenance, function and safety of rail vehicles.
Therefore, highest attention must be given to the optimization of the maintenance processes.
We at MINDA support you in this respect. We implement your specific requirements and specifications with our individual solutions for you.
Product examples for bogie and wheelset handling
Tilting device for bogies
Different types of bogies are clamped on these customized tilting devices and during the painting process they are tilted by ± 45°. This device is driven hydraulically. The stop positions are protected by mechanical interlocking even in case of pipeline damage.
This application-specific turning device is also used for maintenance, cleaning, repair and servicing tasks.
Structure of the tilting device (or turning device)
The tilting device consists laterally of two bearing blocks, between which there is a mounting frame. On the mounting frame there are 4 clamping devices on which the bogie is mounted. The device is fixed to the floor.
A bearing block contains a generously dimensioned drive to cope with the bogies' centers of gravity which might not be located in the axis of rotation. The drive side is protected by a mounted protective hood.
The opposite bearing block can be moved and locked on rails to compensate for different lengths of the bogies.
The electrical control cabinet and the hydraulic unit with attached valve technology are located on a rack outside the spraying booth.
Procedure/ Function
A suitable hoist and 4 rope suspensions are required to insert the bogie into the tilting device. After the bogie frame has been positioned exactly on the 4 clamping devices, the frame is fixed by means of clamping claws.
The tilting process is initiated by extending or retracting a hydraulic cylinder. When the tilting position is changed into the desired direction, the lock is released and the tilting process begins. When the bogie is in the desired position, locking takes place.

Wheelset drop system (exchange of wheels)
The wheelset drop (wheel changing device) is used to lift and lower rail vehicle cars for changing the bolster springs from bogies and for transporting rail vehicle parts (max. 25 t) as well as for transporting the dismantled wheelsets.
It is driven via a belt driven spindle-type lifting gear. The traversing is controlled via remote control.
Basic structure of the wheelset drop system
The wheelset drop system consists of a welded base frame to which a rail-guided travel drive is attached. The travel drive is driven by an electric motor.
There is a lifting frame on each long side. These lifting frames accept a lifting spindle and two linear guides, which guide the lowering table when lateral forces occur.
Platforms are mounted on both sides of the wheelset drop. Two flaps in the platform surfaces enable the transport of rail vehicle parts with a maximum weight of 2 tons.

Lifting and rolling device for wheelset
This semi-automatic lifting-rolling device allows to lift and lower wheelsets between different infeed and outfeed levels. Moreover, the wheelsets can be lifted to ergonomic height for different operations, such as repair, maintenance, painting or cleaning.
Driven contour rollers allow rotating the wheelset in order to reach every position of the wheelset during different operations.
Structure of the customer-specific device for wheelsets
The lifting-rolling device is located on a lifting table, which lifts or lowers the device to working level, ejection level and lifts or lowers the maintenance level. This device can be designed for a fixed track width or also for adjustable track widths.
Furthermore, the device has two final position stoppers, whereby the shock is cushioned by shock absorbers. A backstop prevents the wheelset from rolling back. An ejector serves to roll out of the device.
The lifting table itself is mounted on a steel frame underneath. The lifting and lowering of the lifting table is hydraulic.
This lifting-rolling device is embedded in a pit on site.
Functions of the lifting-rolling device
The machined wheelsets are rolled up from a wheelset magazine onto this application-specific device via a feed track. The infeed rail is lowered and the wheelset is softly positioned onto the rollers.
During painting, the wheelset is rotated via driven contour rollers. The speed, which depends on the viscosity of the color, is infinitely adjustable.
After the painting process, the lifting-rolling device is lowered to the roll-out level by 435 mm and the wheelset is discharged by means of an ejector. The wheelset rolls over a special wedge up to 6 m on the roller track.
This device can be moved to an upper position (900 mm above the feed track) for carrying out maintenance work.
Technical data
All data can be adjusted according to customers`or application-specific requirements.
