From the medical instruments used to sustain us, to the buildings we work and live in, the cars we drive, and the utensils we eat with, the steel industry contributes to product in every sector of the country. We’re proud to be a part of keeping this life supporting industry moving by renting and maintaining specialized steel mill equipment across the country.
Check out some of the heavy equipment machinery that’s an integral part of keeping steel mills moving:
Continuous Transport System (CTS), also known as a Transporter, operates using a series of pallets engineered to hold the material being transported. These large machines have multi-axle maneuverability allowing them to maneuver in tight areas. They elevate hydraulically to lift a pallet from the ground and can be designed to carry 50 to 350 tons. These Continuous Transport Systems add significant efficiency to an operation.Read More
Reach Stackers are typically built for the Intermodal Industry for handling shipping containers. They’re designed to lift these large containers, transport them around a terminal, and stack them many containers high. Because of their unique lifting ability and the excellent visibility when compared with other lifting equipment, these Reach Stackers, once modified, make excellent tools to tackle coil and slab handling in the Steel Industry.Read More
Pot Carriers are engineered to mitigate risk and increase efficiency when handling molten slag, a byproduct of the steel making process. Utilizing a Pot Carrier allows the steelmaker to tap directly into a slag pot.Read More
Kress Straddle Carriers are engineered to increase the ease and handling of slabs direct from the caster to either an inventory yard or rolling mill. They reduce the number of times the slabs are handled, and with the utilization of an inventory program can easily track the movement of the slabs from caster to inventory yard to rolling mill where they are converted to coils. The slabs can be handled hot or cold, and based on the capacity of the carrier in stacks of 4-7, ranging up to 200 tons of material in a single move.Read More
Steel Mill Application (SMA) Front-End Loaders have the base of a tried and tested design with a reinforced frame, cab, and components in order to operate and handle molten steel and blast furnace slag. Designed to protect the operator and reduce the risks when handling molten slag, the front-end loader cab is fitted with impact- and heat-resistant glass. There is also a closed HVAC system to prevent the introduction of gases created when handling the molten slag.Read More
The first Continuous Transport System Bulk supplied to a customer was in 1999. This replaced multiple heavy-duty tractors and trailers along with the labor support required to operate the trucks. Not only were we able to save our customer significant expense by moving from multiple trucks, trailers and drivers to one single machine with one operator, but we were also able to decrease the carbon footprint by burning significantly less fuel while accomplishing the same or more productivity.
With a modified or purpose-built spreader replacing the container spreader, we hang magnets for slab handling and C-hooks or coil tongs for coil movements. When handling hot slabs, purpose-built slab tongs can withstand temperatures up to 1,100 degrees F are attached. Typical lifting capacity under the lifting device can range from 35 to 50 tons depending on attachment weight and configuration. However, there are manufacturers that are now building Reach Stackers with significantly more lifting capacity. As capacity goes up, maneuverability due to increased wheelbase goes down.
The Pot Carrier is constructed to lift and carry a slag pot designed to the specific capacity of the steel maker’s furnace. It also provides the operator with additional safety features in an effort to further reduce the hazards and to allow for ease of handling and transporting the slag pot to an engineered dumping station.
The prime mover, or tractor, utilizes a scraper design and then updates the operator’s cab with the ability to face in the direction of operation. This improves visibility and increases productivity.
The Straddle Carrier increases productivity for the customer by eliminating the use of flatcars to transport slabs throughout the mill. This asset decreases the number of times the slabs are handled by providing the ability to drive directly over top of the slabs, picking them up, and transporting them directly to the location of the customer’s needs. These machines can also pick and sort through slab piles, selecting specific slabs for their orders, and achieving just in time delivery.
When machines are being used in this kind of harsh environment, it’s also necessary to make modifications to make sure it can stand up to the extreme heat. Electrical wiring harnesses, grease lines, and hydraulic hoses are wrapped in heat-resistant wraps and covering to prevent premature failure and ignition sources. Steel tire chains are used to protect the rubber tires, while at the same time adding weight to the machine for handling the molten slag. A specially-engineered bucket allows the SMA Front-End Loader to easily break-up and handle the molten slag. Rubber and plastic elements typically used in a standard Front-End Loader are removed and replaced with high-heat resistant steel components. Belly-pan guards are added to the underside of the SMA Front-End Loader in order to protect the major components, engine, transmission, and torque convertor from the high-heat element of the molten slag.
