Wheel chocks and truck restraints are key for loading dock safety. Chocks can be all weather or optimized for ice, and restraints can be manual or hi-tech.
Frequently Asked Questions
What’s the difference between the StrongArm™ ML10 and SVR303 restraint systems?
The ML10 is a mechanical restraint, 10 ¾” above grade, securing ICC bars from 11″ to 26″ with 30,000 lb of restraining force and an easy-grip control rod so staff can engage or release it from the dock without bending or lifting. The SVR303 is hydraulic and low-profile at 8″ above grade, securing ICC bars from 8″ to 26″ with double-acting hydraulic cylinders rated for wet or flooded conditions and 35,000 lb of restraining force.
What standards do the StrongArm™ restraint systems meet?
Both units comply with NHTSA guidelines for barrier housing profile, and the ML10 also complies with the ANSI MH30.3 standard.
How does PosiLock™ securing technology work?
PosiLock™ is a mechanical locking system that holds the trailer’s ICC bar in place without applying damaging pressure to the deployment mechanism, used on both the ML10 and SVR303.
Can a vehicle restraint be left locked overnight for theft prevention?
Yes. The StrongArm™ ML10 can be left in the locked position overnight to help discourage trailer theft in addition to preventing premature departure during loading and unloading.
What wheel chock options are available and are they OSHA compliant?
American Door offers Molded, Laminated, Aluminum, and Ice wheel chocks, all of which meet OSHA requirements. The Laminated chock is heavy-duty reinforced rubber with a carrying handle; the Aluminum chock is lightweight with strong tire and driveway grip.
Which wheel chock is best for icy or slippery conditions?
The Ice Wheel Chock has a sawtooth bottom that grips icy and slippery surfaces securely, and is powder coated safety yellow for high visibility (10.5″ L x 8″ W x 9.25″ H).
The manually operated StrongArm™ ML10 is engaged and released by a single detachable control rod. Because no bending or lifting is required, the risk of employee strain or injury is significantly reduced.
ANSI MH30.3 tested and approved, the StrongArm™ SVR303 is a low-profile, non-impact design with a rotating arm that seeks a trailer’s ICC bar via a patented, switchless technology.
Once engaged, it uses 35,000 lb (15,909 kg) of restraining force to secure the truck to the dock. Dual-acting hydraulic cylinders prevent lock-up and release problems.
The Intelligent Positioning System (IPS) constantly communicates the location of the restraint arm via a network that enables the integrated lights communication system to accurately display safety conditions at the loading dock.
When it comes to heavy equipment in the shipping and receiving area, safety is always a concern. Blue Giant wheel chocks secure the truck wheels and prevent them from shifting or moving during loading and unloading.
OSHA requires trucks to have their rear wheels chocked and/or the brakes set at all times. For maximum safety two wheel chocks per trailer are recommended (1910.178 (K) 1). Blue Giant wheel chocks help building managers satisfy applicable safety standards and meet both legal and insurance-related obligations.
