rccUnloading of covered railroad cars no longer has to be a time-consuming, hazardous, dirty job.

The BOOT-LIFT® Railcar Connector installs between the rails and provides a dust-tight seal between the railcar discharge and the below-grade conveying system, including vacuum systems.

Rough spot the car, adjust the BOOT-LIFT® Railcar Connector with either the manual or pneumatic aligner, actuate the lifting cylinders, and you’re ready for clean, pollution-free material transfer.

The air over hydraulic lifting cylinders automatically compensates for the leaning and rising of the railcar. Combine the BOOT-LIFT® Railcar Connector with a MARTIN® Railcar Opener and a POCKET ROCK-IT® Vibrator for the optimum in safe, efficient railcar unloading.

BOOT-LIFT® Railcar Connectors help to reduce material-loss, curb air pollution, reduce unloading times, cut housekeeping costs, and only 1 cfm of air is required!

Replaceable Foam Seals

All BOOT-LIFT® Railcar Connectors come with replaceable foam seals that ensure a positive seal even on vacuum systems.

  • Reduce Material Loss
  • Curb Air Pollution
  • Reduce Unloading Times
  • Cut Housekeeping Costs!
  • Only 1 CFM of Air Required


Models SBL & SBLR

The MARTIN® SBL BOOT-LIFT® Connector provides a positive connection between the railcar and the below-grade material handling system. The large funnel opening provides full flow without plugging or interruptions. SBLR units are designed to connect to railcars with round discharges.

Models DBL-18 & DBL-18-GATX for double-pocket cars

The DBL-18 BOOT-LIFT® Connector is the most rugged car unloader available for double-pocket cars. The two 4″ lift cylinders provide over 2,500 lbs. of sealing force. Dual spread cylinders are used to keep the funnels level. A lock bar controls the spread distance.

Bootlift Vertical Connector

The BOOT-LIFT® Vertical Connector was designed by Martin® engineers to provide dust-free/pollution-free unloading of trucks.

Two cylinders bring the sealing boot directly against the discharge of the truck and provide a positive connection throughout the unloading process.
