Kaster heavy duty RollMaster mencakup seri RM-Medium (150–500 kg), RM-Heavy (500–1500 kg), dan RM-Extreme (1500 kg+), dengan diameter roda dari 100 mm hingga 300 mm. Setiap braket dihasilkan dengan las dan diuji beban pada rig pengujian dinamis sebelum perakitan.
Aplikasi umum: skate pemindah mesin, keranjang dies, troli berat, platform gudang, dan peralatan yang harus melaju setiap hari kerja tanpa jendela perawatan.
Spesifikasi
- Kapasitas beban 500–2000 kg per kaster (hitung 3 dari 4 kaster pada beban penuh untuk keamanan lantai tidak rata)
- Braket baja tebal hasil las, finishing pelapisan seng atau pelapisan serbuk
- Bearing bola atau rol presisi, fitur pelumasan sebagai standar
- Uji beban dinamis pada setiap batch produksi
Finishing
Pelapisan seng, pelapisan krom, pelapisan serbuk
| 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
Konsentrisitas roda dan kesejajaran braket sesuai standar QC internal; rating beban berdasarkan protokol pengujian EN 12530
| 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 |
