Save a Load Load Locks
In the commercial trucking and refrigerated freight logistics industries, Save a Load load locks have earned a reputation as the industry standard for hydraulic interior cargo securement bars. Unlike traditional mechanical ratchet-style cargo bars that can crush delicate trailer sidewalls or slip loose when freight shifts on rough highways, Save a Load bars utilize a patented hydraulic pressure cylinder. Designed to absorb trailer flex and maintain constant holding pressure against trailer walls, these lightweight aluminum bars protect valuable freight from transit damage and safeguard dock workers during unloading.
Patented Hydraulic Mechanics and Internal Pressure Release
The core mechanical innovation behind Save a Load cargo bars is an internal closed-loop hydraulic cylinder paired with an internal coil spring. Traditional mechanical jack bars rely on fixed ratchet teeth; as a semi-trailer twists and flexes over potholes and bridge expansion joints, the trailer sidewalls widen momentarily, causing rigid mechanical bars to lose tension and drop to the floor. Save a Load hydraulic bars continuously expand and contract with the flexing walls, maintaining consistent clamping force.
Ergonomics and operator safety represent another critical advantage. Mechanical ratchet bars require high leverage manual pumping that causes frequent shoulder, wrist, and back injuries among drivers and warehouse workers. Save a Load bars require only a few gentle pump strokes on an ergonomic nylon handle to achieve up to 1,200 pounds of holding force. Releasing the bar is accomplished effortlessly via an integrated push-button pressure release valve that relieves hydraulic tension instantly without violent kickback.
The table below compares Save a Load hydraulic cargo bars against conventional mechanical ratchet and lever bars.
| Feature / Metric | Save a Load Hydraulic Bar | Mechanical Ratchet Bar | Lever-Action Steel Bar |
|---|---|---|---|
| Clamping Mechanism | Enclosed Hydraulic Ram System | Exposed Mechanical Ratchet Gear | Over-center manual lever |
| Sidewall Flex Compensation | Dynamic (Spring & Fluid expands) | Rigid (Zero flex; falls when wide) | Rigid (Bends trailer walls) |
| Average Unit Weight | 9.5 to 11.5 lbs (Aircraft aluminum) | 14.0 to 18.0 lbs (Steel tubing) | 16.0 to 20.0 lbs (Heavy steel) |
| Operator Injury Risk | Very Low (Push-button release) | High (Ratchet kickback hazards) | Moderate (Pinched fingers on lever) |
| Trailer Wall Damage | Zero (Pressure-limiting relief) | High (Excessive ratcheting dents walls) | High (Fixed length bows sheet metal) |
| Operating Temperature | -40 °F to 160 °F (Synthetic fluid) | Mechanical (Gears jam with ice) | Mechanical (Ice clogs pivot pins) |
The internal pressure relief valve prevents overzealous operators from pumping excessive force that could buckle composite refrigerated trailer walls.
Fleet Durability, Articulating Foot Pads, and Specialized Configurations
Durability in commercial freight requires corrosion resistance and premium materials. Save a Load bars are manufactured from heavy-wall 6000-series aircraft-grade aluminum alloy, making them impervious to road salts, washdown sanitizers, and moisture inside refrigerated reefer trailers. The bars feature pivoting non-marking rubber foot pads that articulate up to 15 degrees, allowing full surface contact against corrugated, ribbed, or smooth composite trailer liners even when mounted at slight vertical angles.
Save a Load manufactures multiple specialized configurations tailored to specific freight handling environments. Standard heavy-duty bars extend from 84 inches to 114 inches to accommodate standard 102-inch wide commercial dry vans and refrigerated trailers. Heavy-duty models can be fitted with vertical hoop attachments that create a wide containment gate for tall stacked cartons, while specialized locking versions incorporate keyed security locks to deter unauthorized cargo access during regional multi-stop deliveries.
The table below details Save a Load product models, working dimensions, and specialized freight attachments.
| Product Model | Adjustment Span Length | Holding Force Capacity | Specialized Feature | Primary Application |
|---|---|---|---|---|
| SL-30 Heavy-Duty Standard | 84 to 114 Inches | 1,000 to 1,200 lbs Holding Force | Pivoting non-slip rubber pads | Dry van and reefer 53-ft trailers |
| SL-30 with Cargo Hoop | 84 to 114 Inches | 1,000 to 1,200 lbs Holding Force | Bolt-on steel restraint hoop | LTL palletized freight & tall boxes |
| SL-20 Medium Duty Bar | 84 to 114 Inches | 750 to 900 lbs Holding Force | Lightweight aluminum profile | Straight trucks and local box trucks |
| Key-Locking Hydraulic Bar | 84 to 114 Inches | 1,000 to 1,200 lbs Holding Force | Integrated key lock cylinder | High-value pharmaceutical & retail loads |
| Sprinter / Van Mini Bar | 50 to 72 Inches | 600 to 800 lbs Holding Force | Compact short-stroke cylinder | Delivery vans and courier cargo |
Utilizing hoop attachments transforms a single cargo bar into a broad restraint gate, preventing upper pallet tiers from toppling rearward.
How to Secure Cargo with a Save a Load Lock in 4 Steps
Follow this standard operating procedure to position, pump, and release a Save a Load hydraulic cargo bar.
Extend Bar to Match Trailer Sidewall Width
Depress the quick-release pin, slide the telescoping inner aluminum tube outward until foot pads touch both trailer walls, and re-engage the pin.
Position Squarely Against Freight Pallets
Align the bar horizontally across the trailer width at mid-pallet height, ensuring articulating foot pads rest flat against wall ribs.
Pump Hydraulic Handle to Achieve Full Tension
Actuate the ergonomic nylon pump handle 2 to 3 times until the internal pressure relief valve activates, confirming solid grip.
Depress Pressure Release Button to Unload
When opening the trailer at the delivery dock, simply press the thumb release valve to instantly collapse hydraulic pressure safely.
Frequently Asked Questions (9 Questions Answered)
Q1: What makes Save a Load bars different from regular cargo bars?
Save a Load bars utilize an internal hydraulic cylinder and spring mechanism that maintains constant holding pressure as trailer walls flex on the road, whereas mechanical ratchet bars easily vibrate loose.
Q2: Can Save a Load cargo bars damage trailer walls?
No; an integrated hydraulic pressure relief valve limits maximum holding force, preventing over-pumping that damages thin composite or refrigerated walls.
Q3: What is the weight rating of a Save a Load lock?
Standard heavy-duty Save a Load bars provide approximately 1,000 to 1,200 pounds of holding resistance against shifting freight.
Q4: Do Save a Load bars work in freezing reefer trailers?
Yes; they use specialized synthetic aircraft hydraulic fluid that functions reliably in temperatures ranging from -40 °F up to 160 °F.
Q5: How do you release pressure on a Save a Load bar?
Simply push the recessed thumb-release pressure button, which instantly vents hydraulic pressure without any dangerous handle kickback.
Q6: Are Save a Load bars made of steel or aluminum?
They are crafted from heavy-gauge aircraft-quality 6000-series aluminum alloy, making them lightweight (around 10 pounds) and rustproof.
Q7: Can the hydraulic mechanism be rebuilt if it leaks?
Yes; Save a Load provides factory rebuild kits and replacement foot pads, allowing logistics fleets to service bars for years of commercial duty.
Q8: What trailer widths do standard Save a Load bars fit?
They telescope between 84 and 114 inches, fitting standard 96-inch and 102-inch wide commercial dry van and refrigerated freight trailers.
Q9: Why do dock workers prefer hydraulic cargo bars?
The push-button release and easy pump handle virtually eliminate the repetitive wrist, shoulder, and back injuries associated with heavy mechanical ratchet bars.
