Wheel Chocks & Traffic Control

Wheel Chocks & Traffic Control

Wheel chocks and speed bumps solve two related but distinct problems. A wheel chock stops a parked trailer or vehicle from rolling, critical at a loading dock where a trailer rolling away mid-load is a serious hazard, not just an inconvenience. A speed bump or car stop controls how fast and how far a moving vehicle travels, managing traffic flow rather than preventing rollaway.

Material and rating follow the vehicle weight and how often the product gets used. Rubber and urethane chocks handle daily trailer traffic; steel rail chocks step up for rail cars. Speed bumps range from light rubber humps for a parking lot to heavy-duty modular guard curbs for constant industrial traffic.

Chocks Prevent Rollaway, Bumps Control Speed

Preventing Movement vs. Controlling Speed

Chocks Prevent Rollaway, Bumps Control Speed

A wheel chock's job is singular: once placed, the vehicle doesn't move until someone removes it. That makes chock placement a safety procedure as much as a product choice, every trailer at a dock should be chocked before loading begins, every time.

Speed bumps and car stops are a traffic-management tool, not a safety-critical lockout, they shape driver behavior and mark parking or stopping points. Removable options let you take speed control away seasonally or for a temporary layout change; permanent installations suit a fixed traffic pattern.

Applications

Where These Get Used

Loading Dock Trailer Safety

Wheel chocks placed before loading begins prevent a parked trailer from rolling away while forklifts are working inside it.

Rail Car Loading

Steel rail chocks and magnetic rail car wheel chocks handle the specific geometry and weight of rail loading operations.

Parking & Traffic Areas

Speed bumps and car stops manage vehicle speed and parking position across lots, docks, and facility roadways.

Two Different Jobs

Stop a vehicle from moving, or slow it down

Rated to the Vehicle

Rubber, urethane, and steel chock options scale to trailer, truck, and rail car weight: the wrong chock for the vehicle is a real safety gap.

Removable or Permanent Speed Control

Modular and removable speed bumps adjust with seasonal or layout changes; permanent installations suit a fixed traffic pattern.

Built for Constant Use

Oil and salt-resistant materials and reinforced designs hold up to daily industrial traffic, not just occasional use.

The Step That Happens Before Loading Starts

The Step That Happens Before Loading Starts

A trailer backed up to a dock isn't secured just because it's stopped: without a chock in place, it can roll while forklifts are actively working inside it. That's why chocking is standard procedure at every serious loading dock, not an optional add-on.

The right chock depends on the vehicle: rubber and urethane for standard trailer traffic, steel or magnetic rail chocks for the different geometry of rail car loading.

Speed Control Is a Different Problem

Speed Control Is a Different Problem

Where a chock is a lockout, a speed bump is a behavior tool: it shapes how fast and where vehicles travel across a lot or facility roadway, without stopping anything outright. That's why bumps come in removable and modular options that adjust to a changing layout, unlike a chock's single fixed job.

Heavy-duty modular guard curbs step up for constant industrial traffic where a light residential-style speed bump wouldn't hold up.

Frequently Asked Questions

A dock leveler bridges the gap between dock and trailer: it does nothing to stop the trailer itself from rolling. Chocking every trailer before loading begins is a separate, essential safety step regardless of what leveler equipment is in use.
A wheel chock prevents a stationary vehicle from moving at all: a safety-critical lockout. A speed bump manages the speed and path of a moving vehicle: a traffic-control tool, not a safety lockout.
Yes: rail car geometry and weight are different enough that steel rail chocks or magnetic rail car chocks are purpose-built for that application, not a repurposed truck chock.
Yes, removable and modular options exist specifically for layouts that change seasonally or for facilities that need to adjust traffic control periodically.
