Trailer Restraint System

Trailer Restraint System

SP Industries realizes the need for better and stronger ways to keep a trailer in place while loading, especially when using our high density equipment. It is with that need in mind that we created the Dolly-Lok Trailer Restraint System. Not only does this system hold a trailer in the most difficult situations, but it also provides guidance to the trailer to ensure that your trailers are placed the same way each and every time. Utilizing large diameter tube steel, this system provide a high level of durability that is unmatched in the industry.

Often used in transfer stations or in conjunction with our Tractor Trailer Loaders, this system is proven to hold trailers in place while packing a load. This means that you can spot a trailer with confidence. No more will you have a need to leave a truck attached to the trailer in the dock to ensure that the trailer does not move. Getting the most out of your equipment is how SP Industries helps you to be more “green” and improve efficiencies throughout your plant. Call us today to learn more about how the Dolly-Lok system can help you to solve your waste and recycling problems and reduce your overall cost of waste and recycling handling.

We build better

We build better. As a small manufacturer, we focus on quality over quantity.

Attention to Detail

We build custom equipment with close attention to detail. Every piece of equipment we build is tested and inspected on three important criteria: functionality, build quality, and equipment fit & finish. These high standards ensure that every SP Industries customer receives a product capable of outlasting and outperforming the competition (We still have machines in operation that were built in the early 80s!)

Domestically Sourced

We use only domestically sourced structural steel components for our equipment foundations. (e.g. I-beam, C-channel, Tube, Angle, etc.) Many manufacturers cut corners by using formed sheet metal components on their Frames & Rams, impacting the performance and durability of their machines.

High Quality Components

We use high-quality, name-brand components. We have partnered for many years with top suppliers including Baldor Motors, Vickers Pumps & Valves, AB Electrical Components, and US made hydraulic cylinders and binder ratchets. We stock most components for easy replacement or can drop ship parts directly to you from the manufacturer.

USA Flag

We believe in buying American. Today, a huge number of components are made overseas, with varying degrees of quality. At SP Industries, we purchase domestically made products as much as possible and always work with US-based suppliers.
