Trestle Ladder

The Trestle Ladder, also known as a Double Front Ladder, is a self-supporting portable ladder that is non-adjustable in length, and hinged at the top. It consists of two sections and is designed to be climbed by two persons at the same time, one on each side.

Trestle Ladders range in lengths up to 20 ft. as measured along the side rail.  The highest standing level on a Trestle Ladder is slightly more than 2 ft. from the top of the ladder. The highest standing level is required to be marked on the specifications label on the side rail of the product.  Therefore, when planning your job, the maximum work height is established by adding the user's height and reach to the highest standing level.

Proper Use

A Trestle Ladder requires level ground support for all four of its side rails.  If this work site condition does not exist, a Trestle Ladder should not be selected for the job.

A Trestle Ladder must not be used unless its base is spread fully open and the Spreaders locked.  Some Trestle Ladders are equipped with more than one pair of Spreaders, and all must be locked prior to use.

In order to prevent tipping the ladder over sideways due to over-reaching, the user(s) must climb or work with the body near the middle of the steps or rungs. The ladder should be set-up close to the work. Never attempt to move the ladder without first descending, relocating the ladder, and then re-climbing.  Do not attempt to mount the ladder from the side or step from one ladder to another unless the ladder is secured against sideways motion.

In an effort to avoid losing your balance and falling off the Trestle Ladder, the user must not step or stand higher than the step indicated on the label marking the highest standing level.

When ascending or descending the ladder, always face the ladder and maintain a firm hold.  Do not attempt to carry other objects in your hand(s) while climbing. 

The anti-slip feet at the bottom of the Trestle Ladder side rails must be present and in good condition prior to using the ladder.  The ladder must not be used on ice, snow or slippery surfaces unless suitable means to prevent slipping is employed.  

A Trestle Ladder must never be placed upon other objects such as boxes, barrels,  scaffolds, or other unstable bases in an effort to obtain additional height.

Proper Care

A thorough inspection must be made when the ladder is initially purchased and each time it is placed in to service. Clean the climbing and gripping surfaces if they have been subjected to oil, grease or slippery materials.  Working parts, bolts, rivets, step-to-side rail connections, and the condition of the anti-slip feet (safety shoes) shall be checked.  If structural damage, missing parts, or any other hazardous defect is found, the ladder must not be placed into service and either discarded or competently repaired. 

Ladders exposed to excessive heat, as in the case of fire, may have reduced strength.  Similarly, ladders exposed to corrosive substances such as acids or alkali materials may experience chemical corrosion and a resulting reduction in strength.  Remove these ladders from service. 

Ladders with bent or broken side rails must be destroyed.

In the event a ladder is discarded, it must be destroyed in such a manner as to render it useless.  Another person must not be afforded the opportunity to use a ladder that has been deemed unsafe.

When transporting ladders on vehicles equipped with ladder racks, the ladders must be properly supported. Overhang of the ladders beyond the support points of the rack should be minimized.  The support points should be constructed of material such as wood or rubber-covered pipe to minimize the effects of vibration, chafing and road shock.  Securing the ladder to each support point will greatly reduce the damaging effects of road shock.

Storage racks for ladders not in use should have sufficient supporting points to avoid sagging which can result in warping the ladder.  Other materials must not be placed on the ladder while it is in storage.
