Air-Powered Dock Levelers

Air-powered technology is a common tool used for heavy lifting in the mining, building and construction industries, and our Air Bag Dock Leveler utilizes this technology to provide proven, long-term, reliable service on the loading dock every day. Compared to mechanical dock levelers, the Air Bag Dock Leveler is safer and far easier to operate. To raise, simply push a button. There’s no back-wrenching pulling of chains, walking down the deck and, best of all, no springs or hold-down to repair or replace.

Hydraulic Dock Levelers

Hydraulic dock levelers are designed for fast, easy and safe push-button operation, and LDS offers the best in the industry. Standard features like premier lug-style lip hinges, simplified hydraulics, internal velocity fuses and modified open frame designs make Kelley hydraulic dock levelers the preferred equipment choice.

Mechanical Dock Levelers

LDS offers the industry’s best features in its cost-effective mechanical dock leveler. Premium features such as single point adjustment main springs and integral maintenance struts make our mechanical dock levelers your best choice, and our mechanical levelers are warranted to be one of the best investments you can make to enhance dock safety and productivity.

Power Assisted Dock Levelers

Power-Assisted Levelers provide the ultimate reliability and flexibility in today’s fast-moving loading dock environment. The PAL is ideal for customers whose workloads demand more performance than a mechanical leveler can deliver. Our power-assisted dock leveler is simple to operate, reduces downtime and provides higher operational efficiency to provide the perfect balance of power and performance.

Unlike mechanicals with a powerful upward bias, the PAL utilizes a hydraulic power-pack assembly and counterbalance assist to produce a slight downward bias. By eliminating pull-chain hold-down mechanisms, adjustable lip extensions and the necessity to walk down decks, the PAL eliminates the physical demands required to operate mechanical levelers.

The PAL also eliminates stump-out using a patented sensor roller that rides along a reinforced cam surface, providing fluid free-float motion while also adding a measure of free-fall protection in the event of premature trailer separation.

Vertical Dock Levelers

Maintaining a clean, efficient warehouse environment is critical for a growing number of companies operating climate-controlled facilities. Vertical Dock Levelers directly contribute to environmental efficiency, security and cleanliness, allowing you to take control of your warehouse.

Load Hog® Modular Dock-bridge

For years, warehousing operations have been asking for a better solution for their loading dock needs than edge-of-dock levelers, portable plates and many types of mechanical pit-styled dock levelers can provide.

The LoadHog is a modular dock bridge designed to span the gap between the warehouse and the trailer. It mounts to the warehouse floor using only four heavy duty anchor bolts and requires no concrete work. The bumper block assembly attaches to the face of the dock with four anchors per bumper.

The compressible foam side frame prevents damage from off-centered trailers.

Wheel Restraints

For trucks with lift gates, damaged rear impact guards, or those without rear impact guards, conventional restraints just won’t work. That’s why LDS offers reliable wheel restraints to secure virtually any truck or trailer configuration, assuring safe, efficient loading dock operations.
