Whiting Portable Electric Jacks

Rugged Design, Painless Maintenance

Found in maintenance shops and rail yards across North America, the Whiting Portable Electric Jack is the industry standard that continues to outlast the competition.


With minimal required maintenance, this rugged design handles the toughest conditions found in railcar and locomotive shops.


All Whiting Jacks start with a welded steel base and structural steel column. Connected to this frame, the alloy steel jack screw is keyed to a worm gear supported by a large thrust bearing.


The jack screw uses precision-machined buttress threads. In this application, Buttress threads are more efficient and safer than other threads. The aluminum bronze nut travels on the screw and supports the welded steel lifting bracket.


The result is a Portable Electric Jack with dependable load-lifting capacity at any point within the lifting range.


Whiting portable electric rail jacks have many features that make your decision to choose jacks from Whiting an easy one, including:

Tough Construction
Welded to the base is a massive structural steel column assembly housing an alloy steel jackscrew and aluminum bronze alloy jack nut.

Electro-Mechanical Design
Whiting portable electric jacks consist of a steel base containing a worm and worm gear. The jack nut travels on the screw and supports the lifting bracket.

Interlocking Controls
A single operator manning a portable electric jack station can control the simultaneous operation of any number of jacks. Each jack may also be operated individually.

Specialized Bracket Design
Jacks can be equipped with a variety of special lifting brackets.

Additional Options For Portable Jacks

 Zero Speed Shutdown Kit

The addition of this feature will prevent a jack set from becoming unequally loaded or a vehicle tilted if any one of the jacks in the set stops due to a failure in the drive chain. If one jack screw stops, they will all stop and a red fault light on the relay panel will illuminate, identifying the malfunctioning jack. This fault will not allow the set to operate from the pendant station until the problem is corrected.

Upper Over Travel Limit Switch

The addition of this backup limit switch assembly provides a means for eliminating the danger of damage to a jack or a raised vehicle should the normal upper travel limit switch malfunction at the top of the lifting bracket’s allowable travel. The programming will allow the operator to lower the vehicle. Until the malfunctioning limit switch is repaired or replaced, the jack will not lift the vehicle.

Nut Wear Indicator and Follower Nut

The addition of this dual purpose system allows the user to monitor unseen wear of jack nut threads, visually and electronically. It also prevents the loss of a load should the threads of a nut fail. An electronic sensing device is set to read the maximum allowable wear of a nut. Upon reaching this point, a signal commands the other jacks in the set to stop. A red light on the control panel will illuminate and shut down the system until repaired.

Automatic Nut Lubricator

The addition of this feature eliminates the problems of over and under greasing of jack screws and nuts. A small quantity of lubricant is directly injected onto the threads of the jack nut during operation and adds to the original thin coat application. The life of the remotely mounted and easily accessible cartridge depends on usage.
