specifically designed for retrieval of stock from shelving. The ladders roll along a track that is mounted
on the shelving. Each of the three products has distinctive features that are suited for the varying
requirements of our customers. The primary application for Track Ladder systems is in retail stores,
and much of our innovation in design of these products stems from working with national store chains.


Single Trak Ladder

Steel Mounted Shelf Ladder

Easy access to shelves in narrow aisles and cramped storage areas.

These ladders have a smooth rolling upper track fixture and wheels on the floor that allow easy movement of the ladder along the entire length of the track. The upper rolling trolley fixture is mounted on straight track at the front shelf edge. The rugged all-welded steel construction features 5" deep by 14" wide solid steps with abrasive treads.

Quick access... easy to use... easy to store

When in use, the ladder is positioned at an 80° climbing angle. The standard bottom wheel brake prevents movement during use. An exclusive design permits storage of the ladder in a tight vertical position against the shelves when not in use and allows easy passage of persons or equipment in the aisle.

Designed to provide safe, convenient access to tall rack shelving.

Designed to provide safe, convenient access to tall rack shelving. The patented Dual Side Trak Ladder is designed to provide safe, convenient access to tall rack shelving in high traffic areas. Dual Side Trak Ladders typically use up to 50% less aisle space than free standing ladders.

The result is a single ladder that can reach up to 16 feet of shelving with as little as 20" of floor space.

Comfortable climbing angle for fast access to storage

A comfortable 50° stairway with large tread steps and handrails allows easy ascent and forward descent. A 42" guardrail extends above the ladder for use while standing on the large 27" deep top platform. Manually propelled, the ladder rolls smoothly along the length of the stockroom aisle and the upper rolling carriage and its swivel casters at the bottom of the ladder. The swivel casters are easily activated or deactivated permitting the ladder to be moved to each position. It sits firmly in its rubber pad legs while in use. In addition, the carriage itself incorporates a pivoting design to allow easy inward and outward movement of the ladder around aisle- or rack-mounted obstacles.

From the chart below select the proper track height range. (Keep in mind to calculate the distance from the floor to the desired track mounting surface which should be no more than 4 feet below the top of the highest merchandise to be reached.
