Railquip, inc. Rerailing System
Overview
The
Railquip, inc. Rerailing Systems are currently used on
many transit systems and railroads in more
than 70 countries. The System is designed with a double-acting re-pressure system that
enables you to completely and accurately control all operations to the nearest mm. All
hydraulic components are protected against accidental lowering, overload, and
misoperation. Each component operates smoothly and accurately even under full load.
System components can be purchased that allow you to rerail all types of railroad vehicles from the lightest transit vehicle to the heaviest locomotive.
Control Unit
The Control Unit is the central point from which all operations
of the rerailing process can be controlled. It allows the connection of four hydraulic
components. You can connect more components by using distributor valves (order no. 09-2200). The
Control Unit is contained in a portable frame with carrying handles and is supported by
four rugged legs.
Hydraulic Power Units
The Hydraulic Power
Unit can be equipped with a variety of power sources including a four-stroke gasoline
engine, a diesel engine, or an electric motor. The units can also be purchased in regular
size or small size. The electric motor models can also be equipped with an integrated
Control Stand. The units range in weight from 121 pounds to 291 pounds. The hydraulic
flow ranges from 0.60 gallons per minute to 3.0 gallons per minute.
You can also purchase a Hand Pump Power Unit. This is an complete and independent unit for small rerailing jobs. These units are especially useful where you cannot use a combustion engine, e.g. due to explosion hazard.
Finally, you can purchase an Add-On Power Unit that attaches to a work vehicle's hydraulic system. These units are typically plumbed into the hirail gear power source.
Hydraulic
Lifting Jacks
The Lifting Jacks are the workhorses of the rerailing
operations. As you can see in the following table, a large variety of sizes are available.
Minimum |
Maximum |
|
Closed Height |
5 inches |
18.5 inches |
Number of Pistons |

25 inches |
Rated Lifting Capacity |
20 metric tons |
1200 metric tons |
Weight of Jack |
48.5 US pounds |
174 US pounds |
All Lifting Jacks are constructed of high-strength light-metal alloy and operate with pressure of 300 bar or approximately 4410 psi. All jacks are equipped with pressure protection that prevents accidental lowering of the load, e.g. severed hose. The jacks are designed to operate smoothly and safely under full load conditions.
Flat-type, or "pancake" Lifting Jacks are available to deal with extremely low lifting points. Most Lifting Jacks, including the "pancake" jacks can be equipped with piston support pieces and cylinder support rings to increase the effective jacking height.
Finally, in addition to the standard line of Lifting Jacks, a large selection of specialty jacks is available.
Displacing
Jacks
When combined with Counter Supports and Roller Carriages you can laterally push or pull a lifted load with
the Displacing Jacks on top of the Rerailing
Bridge. The Displacing Jack has a pushing capacity of 13 US tons and a pulling
capacity of 6.7 US tons.
Roller Carriage
The Roller Carriage is used to
support and laterally move the lifted load on top of the Rerailing Bridge. Roller
Carriages can be purchased in a variety of heights and in pivoting and non-pivoting
versions.
Rerailing
Bridges
The
Rerailing Bridges allow you to use your lateral displacing equipment to push or pull your
train back onto the track. The Bridges are constructed of an extruded high-strength
light-metal alloy. The surface is protected by a special anti-corrosion compound. The
Bridges are equipped with four extendable carrying handles. Bored holes are on the top
side of each Bridge to allow the anchoring of your lateral displacement equipment.
You can purchase the Rerailing Bridges in two heights, 3.7 inches (95 mm) or 7 inches (180 mm). Over an unsupported span of 4.9 feet (1.5 m) the 3.7 inch high Bridge can support 11 US tons and the 7 inch high Bridge can support 67 US tons. A fully supported 7 inch high Bridge can support 134 US tons and a fully supported 3.7 inch high Bridge can support 67 US tons.
All Bridges can be coupled together using a Bridge Coupler to extend the working length.
Optional Equipment
You can purchase many pieces
of optional equipment that can help you solve rerailing problems. Three of the most
important include,
Safety
Safety must be your first
priority at any derailment site. Definition of a total safety plan is beyond the scope of
this guide, but some important safety items to consider include:
Leadership
It is critical that one,
and only one person be in charge of the rerailing operation.
Interdepartmental Cooperation
Cooperation between
all departments is a critical success factor, especially between the track, power, signal,
vehicle, and operating departments. If they are available on your property, other
departments such as Public Relations and Police can provide invaluable assistance.
Training
The rerailing team
must be thoroughly trained and drilled - prior to any derailment. Your local fire
department can serve as an excellent training and drilling model. It is recommended that
the rerailing team conduct periodic drills and that the team be provided with
communications devices to ensure that they can be contacted when needed. It is also
recommended that the vehicle, track, and bridge departments be represented on the team.
Maintenance
You must maintain
your rerailing equipment to ensure success. It is recommended that you establish a
scheduled preventive maintenance program to address these requirements.
Ancillary
Tools
You will need
certain additional hand tools to be successful. It is recommended that you examine your
rail vehicle and have the tools necessary to disconnect components such as trucks,
couplers, and communications antennas.
Rerailing
Equipment Storage
It is recommended
that you store your equipment in modular units so that the equipment can be deployed
rapidly. Some systems have invested in dedicated carrier vehicles while others have opted
for palletized storage units that can be quickly
loaded onto the Rerailing
Hirail Trailer or other work vehicles.
