Aluminum and steel replacement frames for B&P Liberator and Aristocrat hand trucks. Every frame is bolted top and bottom with aircraft-quality rivets to spread stress across four-sided ribbed cross-straps so a frame outlasts the wheels under it.
Every replacement frame on this page maps to a B-code from B&P’s configuration system. Match the code stamped on your old frame (or check your A-B-C-D part number) before ordering. If your hand truck wasn’t made by B&P, these frames will not fit — check our universal hand truck parts instead.
| B-Code | Frame Type | Capacity | Common Use | Material |
|---|---|---|---|---|
| B1 | Straight back, standard | 600 lb | Liberator daily route | Aluminum |
| B1#02 | Straight back, red anodized | 600 lb | Brand-color fleet builds | Aluminum |
| B5 | Curved back | 600 lb | Drum, keg, barrel work | Aluminum |
| B10 | Straight back, lighter spec | 500 lb | Junior & Senior Liberator | Aluminum |
| B11 | Extending straight back | 500 lb | Tall or oversize cartons | Aluminum |
| B14 | Extending with U-brace | 500 lb | Appliance & vending | Aluminum + steel |
| B-Steel | HD steel straight back | 900–1000 lb | Industrial & foundry | Steel |
Every B&P aluminum frame uses 6063-T6 extruded rail with four-sided ribbed cross-straps. The cross-straps are bolted top and bottom, not just at the nose plate, so impact load gets distributed instead of concentrating at one weld. That’s why an aluminum B&P frame holds 600 lb without flexing while a stamped-steel competitor frame at the same capacity will start showing cracks at the crossbar within 18 months of route work.
Military-grade rivets keep the frame square under repeat curb impacts. When the wheel set, handle, or nose plate wears out, the frame is usually still serviceable — which is why CasterHQ stocks frames as a separate SKU instead of forcing a full-truck replacement.
