Weighwell Portable Train Weigher (PTW) for rail vehicles

Weighwell Engineering Ltd has over 30 years of experience within the global rail sector and has established an unrivalled reputation for safety, reliability and quality of service. Weighwell are renowned for the patented Portable Train Weigher (PTW) with hundreds of weighing systems in over 30 countries worldwide. This has led to longstanding relationships with some of the most prestigious rail companies in the world. At the forefront of innovation, Weighwell invented and developed a portable rail scale that has revolutionised the traditional method of weighing rolling stock.
 
The PTW allows for either static or in-motion (dynamic) train weighing with the flexibility to weigh the single axle, bogie (truck) or full railcar with highly accurate individual wheel weights. This is beneficial in highlighting the weight distribution of the rail vehicle or identifying overloaded (or wrongly loaded) trains. The portable train weighing system can be conveniently installed between rail fastenings (from a length of 500mm) with no need for expensive or permanent track modifications. The PTW can operate through an easy to use digital indicator or via the industry leading ptwX software and is an economical solution that will satisfy any budget. The PTW is available for short term hire (one day), long term hire or purchase.

IVM POWERVE - POrtable WEigher for Railway VEhicles

POWERVE is a hand-portable system able to measure the vertical force load from each wheel of a railway vehicle on the rail.

• Would you like to measure a rolling stock anywhere in the field easily carry by hand your measurement system?
• Would you like to fast install/unistall and move your measurement system in your depot in order to easily measure the rolling stocks on different tracks?
• Would you like enough measurement accuracy in order to set the best rolling stock balance?
• Would you like to automatically obtain a measurement report already in line with the new prEN 15654-2 requirements?
• Would you like a dedicated Cloud database to store and manage the performed measurements?

POWERVE is your solution:

1. Each Wheelset Kit is very lightweight (25kg split in 2 transport cases).
2. The installation doesn’t require any fixing or spacers, just lean the system on the rail on a straight track!
3. Wheel measuring unit category: 0.5 according to ISO 7500-1. Moreover, the system accuracy <1% has been certified in field by a Notified Body;
4. The measurement report at the end of the measurement contains all the fundamental quantities and elaborations according to the prEN 15654-2, to be easily evaluated by the technicians.
5. The SW on the tablet manages the measurement process, and automatically upload the obtained results to the Cloud. The measurements can be downloaded from the Cloud in several common formats (Excel, CSV, PDF, etc.)

It measures on a straight track, and the load cells are interposed just between the top of the rail and the wheel tyre at the wheel/rail interface, not on the wheel flange. POWERVE measures the true rolling stock balance on the track, preventing derailments.

During the life of any rail vehicle, without considering weight changes, the distribution of the wheel forces is mainly a function of the wear of the wheel rolling surfaces diameters and by the suspensions stiffness. So, especially for mantained vehicles with worn wheels, measuring on the wheel tyre near the wheel reference point instead of other points as the wheel flange or the axle box is fundamental to correctly understand the real rolling stock balance on the track.

Obtaining the best wheel force distribution allows to improve the running safety and extend the life cycle of the wheels and the rails, because it minimizes potential slips during traction and braking
