Kaster tetap tidak berputar arah — keranjang melaju lurus. Dalam konfigurasi klasik dua-putar + dua-tetap, mereka memberikan kestabilan dan arah jalan sementara kaster putar yang mengemudikan.
Karena braket tetap tidak punya rel bearing, ia mengusung beban lebih besar dan membutuhkan gaya lebih kecil daripada kaster putar berukuran sama: keranjang berat sering berjalan dengan sepasang kaster putar dan sepasang kaster tetap.
Aturan praktisnya: semakin banyak perjalanan keranjang berupa garis lurus, semakin besar pengembalian kaster tetap. Lorong panjang, rangkaian keranjang ditarik, dan keranjang terpandu rel adalah kasus alaminya; manuver ketat dengan banyak belokan membutuhkan kaster putar.
Spesifikasi
- Rating beban lebih tinggi daripada versi putar berukuran sama
- Braket tetap hasil las, pemasangan pelat atau lubang baut
- Opsi roda yang sama dengan lini kaster putar
- Kaster putar pengunci arah tersedia bila kaster tetap penuh terlalu kaku
Finishing
Seng, pelapisan serbuk, stainless
| Bracket finish | What it does | Specify it when |
|---|---|---|
| Zinc plating (blue/white) | Baseline corrosion protection | Standard dry indoor use |
| Chrome plating | Hard, decorative, easy to clean | Visible / cleanroom-adjacent equipment |
| Powder coating | Custom color, good corrosion resistance | Brand colors, outdoor-adjacent use |
| Stainless steel 304 | No plating to fail | Washdown, food, medical |
| Stainless steel 316 | Resists chlorides | Salt, brine, marine air, harsh cleaning chemicals |
Pengujian
Kesejajaran as dan braket diperiksa per batch
| Selection factor | Rule of thumb | Effect on performance |
|---|---|---|
| Load sizing | Total load ÷ 3 (not ÷ 4) | On uneven floors only three wheels carry the cart |
| Wheel diameter | Bigger rolls easier | Larger wheels cut push force and bridge gaps |
| Tread hardness | Softer = quieter, harder = easier rolling | Pick the softest tread that carries the load |
| Bearing choice | Precision ball for manual pushing, roller for heavy loads | Bearings dominate rolling resistance at high load |
| Swivel vs rigid | 2 swivel + 2 rigid is the standard cart setup | All-swivel carts wander; all-rigid carts cannot steer |
| Floor condition | Rough floors need bigger wheels and softer treads | Small hard wheels on bad floors destroy both |
