INDUSTRIAL WHEEL CHOCKS

FOR ALL INDUSTRIAL APPLICATIONS

WHEEL CHOCK USER GUIDELINES

Wheel chocks are effective holding devices, but only when used
properly. Namely, chocks must be used in pairs and positioned
downhill and below the vehicles center of gravity. This could mean
chocking in front of the front wheels if the vehicle is disabled while
traveling down a grade or the back of the rear wheels if the vehicle is
disabled while traveling up a grade. This could also mean chocking the
front and back of one wheel if the direction of the grade cannot be
determined or even using multiple pairs of chocks in severe conditions.
Although these are generally accepted chocking procedures, it is the decision
of each individual end user to make the final determination about chocking.

Various combinations of chocking procedures should be evaluated and tested
under various situations and conditions.

Wheel chocks should be used not only when a vehicle becomes disabled on a
grade, but also during maintenance and any time the vehicle is left unattended.

Chocks must also be positioned snugly and squarely against the center of the
tire tread. Improper positioning decreases the wheel chock’s effectiveness.
Chocks should be used only after the parking brake is applied and tested.

OSHA SPECIFIES

1910.178 (k) Trucks and railroad cars. (1) the

brakes of highway trucks shall be set and wheel

chocks placed under the rear wheels to prevent

the trucks from rolling while they are boarded

with powered industrial trucks.

WHEEL CHOCKS

LEVEL GRADE

Chock both sides of wheel

WARNING!

Individual end user testing required to ensure proper chock selection
and application

• Improper use may result in product failure

• Select wheel chock according to vehicle type and size

• Always use in pairs and on firm surfaces

• Multiple pairs may be required in extreme conditions

• Chock in direction of grade

• Chock both sides of wheel if direction of grade is undetermined

• Use only after parking brake is applied and tested

• Center chocks snugly and squarely against tread of each wheel

• Always test chocks to ensure they meet requirements

• Do not drive over wheel chocks

These guidelines are for land vehicle use only - NOT for aircraft!

INDUSTRIAL WHEEL CHOCKS

WHEEL CHOCK USER GUIDELINES

There are many considerations that must be taken into account before implementing chocking
procedures. If wheel chocks are expected to hold on a specific grade, then all of the variables that
may affect the chock’s performance must be taken into account:

A. Tire size

B. Tire Type (Pneumatic, Radial, Bias-Ply, Solid Rubber, etc.)

C. Gross vehicle weight

D. Varying tire pressures that naturally occur with changes in the environment

E. Type and condition of road surface (i.e. asphalt, gravel, dirt, firm, soft, wet, dry, icy, etc.)

You cannot simply test a pair of chocks with a specific vehicle and payload, and broadly assume
that the chocks will hold the same vehicle on the same grade every time. Countless combinations
of conditions exist and this must be considered when selecting the most appropriate wheel chock
for each application. Complete and thorough testing must be completed to ensure that specific
wheel chocks will meet your specific chocking requirements.

FOR ALL INDUSTRIAL APPLICATIONS

WHEEL CHOCKS

A variety of chocks should be tested to determine the best chock for your particular application.
