Rail Car Loading and Unloading


Boot-Lift® Railcar Connector

Boot-Lift® Railcar Connector improves the speed and safety of connecting a hopper car to under-track systems, without workers crawling under the car and without losing material to wind or contamination.

Features and Benefits:

  • Boot prevents material loss, air pollution and contamination.
  • Boots are automatically connected.
  • Connector rises as railcar empties.
  • Unit uses only 10 cfm at 90 psi (28 l/min. at 6.2 bar).
  • Including double or single-pocket, round-opening and GATX. Adapter plates allow interchangeability.


  • Manual Aligner - simplifies car positioning by allowing adjustment of the Boot-Lift® Railcar Connector up to six inches (152 mm) total – three inches (76 mm) in either direction – along the track.
  • Pneumatic Aligner - air-powered aligner provides eight inches (203 mm) of total adjustment – four inches (102 mm) in either direction – along the track. Remote control operation requires only 10 psi (0.7 bar) of air.

Railcar Opening


Gate Jack Opener

The Martin® Gate Jack Opener is a single worker-portable, air-operated system that opens stubborn railcar gates quickly, without risking back injury or needing extra personnel.


  • Reduce operating expenses:
  • Spot the car, open the gate and start unloading. There's no time wasted trying to muscle the gate open.
  • Operates from an 80 to 125 psi (5.5 to 8.5 bar) air supply at 70 cfm (1982 L/m).
  • Supplied with hoses and hand-held control valve.

Railcar Opener

Martin® Railcar Opener is an adjustable air-powered opener that maneuvers easily on three wheels to release the most stubborn hopper car gates and start efficient unloading.

Features and Benefits:

  • Powers open the most stubborn hopper car gate with 2700 ft-lb (3661 N-m) of torque at 90 psi (6.2 bar).
  • Pivoting wheels allow unit to maintain contact with traveling capstan of rack and pinion gate opener on hopper cars.
  • Smooth, non-impacting force opens gates without costly damage.
  • Operates from 90-120 psi (6.2 to 8.2 bar), air supply at 20 cfm (566 L/min). Noise measured at 95 dBA at operator position is acceptable for plant operations.
  • Adjustable base allows one worker to maneuver wheeled cart through tight spaces. Height-adjustable unit fits any ground condition beside.

Railcar Material Flow Aid (Vibration)


Portable Railcar Vibrator

Martin® Engineering has developed a convenient portable railcar vibrator with a shoe-slide mount to easily fit into the female bracket on hoppers. Once installed, it provides a powerful force that makes unloading bulk material from railway cars more efficient with less carryback.

Features and Benefits:

  • Vibrator system with three-inch (76-mm) piston
  • Force up to 985 pounds (4381 N) at 80 psi (5.5 bar)
  • Durable mounting shoe slides readily into the female bracket that is on the bottom of railcar hoppers

Brute® Motor Driven Railcar Vibrator

Get high-energy vibration from the Brute® Motor Driven Railcar Vibrator. It clamps on railcar sills to improve the emptying process of compacted material inside railcar hoppers.

Features and Benefits:

  • Does not need lubrication until after 500 hours of service
  • Professional-grade ductile iron case for the greatest durability
  • Low-maintenance bearing operation
  • Reduces power consumption with a more powerful and efficient motor
  • Less operating noise from tapped exhaust port and optional muffler installation
  • Ability to tune force output with adjustable eccentrics for each application


  • Compatible with pneumatic or hydraulic motors
  • Four different mounting options available, depending on these unit types:
    • CCV Series - Integral clamp foot for powerful, portable vibrators used for railcar unloading
    • DV Series – Four- or six-bolt-hole mount bases for permanent installation on large vessels
    • CV Series – Two bolt-hole permanent mounts for hoppers, bins, or chutes
    • CC Series – Cradle lug brackets ideal for applications requiring portability and position changes

Cougar® Impacting Railcar Vibrator

Deliver forceful impacts with powerful vibration to loosen and unload compacted materials from hopper cars with the Cougar® Impacting Railcar Vibrator. Manufactured from Martin® Engineering, this railcar shaker system keeps railcar unloading processes clean, safe, and efficient.

Features and Benefits:

  • Boost and dislodge stubborn material flow with a powerful force from linear vibrators
  • Shoe-slide mounts make mounting and dismounting a strain-free procedure
  • Compact vibrator and mount assembly provides plenty of power to unload the most stubborn materials.
  • Compact, lightweight design weighing only 48 lbs (21 kg) helps reduce the risk of injury from manhandling large, cumbersome vibrators into railcar brackets
  • The Cougar® Impacting Railcar Vibrator is covered by Martin® Engineering's “absolutely no excuses” guarantee.
