Mulzer Crushed Stone

Following three years of successful operation with its first 1500 Series barge-mounted E-Crane, Mulzer Crushed Stone ordered a second E-Crane in 2014 for its Shamblin Stone operation in Dunbar, West Virginia. The floating 700 Series E-Crane unloads aggregate barges directly into a hopper on an adjacent barge, combining productive bulk handling with the flexibility to relocate the complete unloading system.

Inland river terminals

Attachment:

3,0 m³/ 3.9 yd³ Hydraulic Clamshell Grab

Duty Cycle Capacity:

The Challenge:
Creating a Flexible Barge Unloading System for Aggregate

Mulzer needed an efficient barge unloading solution for its Shamblin Stone operation that could reliably handle large volumes of aggregate. Flexibility was equally important, as the company wanted to be able to move the unloading operation to different locations as requirements changed. Rather than creating a permanently fixed terminal, Mulzer required a system that could be transported as a complete unit. The positive experience with its first barge-mounted E-Crane provided a proven foundation for expanding this approach to the Dunbar operation.

“Unloading as much as 4500 tons in a 10 hour shift is not a problem for this model E-Crane®, we are very satisfied with this material handler after unloading 142 barges with it.”

Mr. Robert Caruthers – Shamblin Stone

“The machine is performing well and meeting our expectations. Normally when we commission a new machine there are always some issues to work out. With E-Crane®, those issues were addressed quickly and the machine is operating very smoothly. We have since purchased our third E-Crane® and are expecting it to be delivered this week.”

Mr. Don Gengelbach

The Solution:
Mobile Barge Unloading with Proven E-Crane Technology

Building on Mulzer’s experience with its first E-Crane, the second machine was configured as a floating unloading system for the Shamblin Stone operation. Mounting the crane and receiving equipment on separate barges provides an efficient material flow while allowing the complete system to be relocated when needed.

The solution includes:

  • A 700 Series / EH4248 PD-E E-Crane with 24.8 m / 81.5 ft reach, configured for aggregate barge unloading.

  • A 3.0 m³ / 3.9 yd³ hydraulic clamshell grab with 13.6 Mtons / 15.0 UStons lift capacity for efficient bulk material handling.

  • A barge-mounted configuration, unloading aggregate directly into a hopper located on an adjacent barge.

  • A 132 kW / 177 hp electric motor, providing electric-powered operation within a floating system that can be transported wherever Mulzer needs to perform barge unloading.

BUSINESS OUTCOME

The E-Crane can unload as much as 4,500 tons during a 10-hour shift, and Mulzer reported being very satisfied after unloading 142 barges with the machine. Its successful performance also contributed to Mulzer becoming a repeat E-Crane customer, with the company subsequently purchasing a third E-Crane.
