The ACT Group splices conveyor belts across Los Angeles County — hot and cold vulcanizing, mechanical fasteners and emergency belt repair for the aggregate pits of Irwindale and Sun Valley, the port and rail terminals, the recyclers of Vernon and Commerce, and every batch plant in between. Crews dispatch 24/7 from Fontana with the press, the fasteners and 20,000+ feet of belting on the truck.
Every conveyor in Los Angeles County is on a clock. The aggregate belts in the San Gabriel Valley feed the region’s concrete; the terminal belts at the harbor unload ships on demurrage; the recycling lines in Vernon run three shifts. A failed splice on any of them is measured in dollars per hour, and the closest competent splicing crew is usually the one that wins the job. Since 1991 that crew has been ours — based in Fontana, about an hour from downtown, with a vulcanizing press and belting on the truck. Our belt customers in the region include Cemex, Granite Construction and CalPortland.
Hot Vulcanized Strength: A hot splice runs at nearly the full rated tension of the belt and disappears into it — no metal to catch cleaners, skirting or pulleys. Our standard for primary crushers, overland belts and anything that cannot afford a second failure.
Cold Splices When Time Wins: Cold-bond splices for lighter belts and tight windows where a heated press is impractical — clean, endless and fast.
Belting in Stock: 20,000+ feet of belting in Fontana across common widths and grades, so a section replacement or a new belt does not wait on a distributor in another state.
Hot and cold vulcanized splices: Plies stepped, cemented and cured in a portable press on your conveyor; or chemically bonded cold splices where the schedule demands.
Mechanical fasteners: Hinged and solid-plate fasteners installed to spec for temporary repairs and applications where a mechanical joint is the right answer.
Emergency belt repair, 24/7: Rips, tears, edge damage and failed splices. Call (888) 480-0680 at any hour and a crew is moving from Fontana.
Belt installation and replacement: New belt pulled in, spliced endless, tracked and commissioned around your shutdown — see conveyor belt services.
Tracking and the reasons it failed: Idlers, pulley lagging, cleaners and skirting inspected and replaced on the same visit so the new splice is not the next casualty.
Irwindale, Azusa, Baldwin Park and the San Gabriel Valley; Sun Valley, Pacoima and the San Fernando Valley; Vernon, Commerce, City of Industry and Santa Fe Springs; Long Beach, San Pedro, Wilmington, Carson and the South Bay; Santa Clarita, Palmdale and Lancaster; Downey and the Gateway Cities — and Orange County on the same dispatch.
Belt down in Irwindale at 2 a.m.? Call. Shutdown in Long Beach next month? Send the belt specs and we will quote the splice, the belt and the parts that should change while the conveyor is stopped.

An hour from downtown, with the press and the belt on the truck
Mechanical fasteners hold a fraction of a belt’s rated tension and wear everything they run over. A hot vulcanized splice disappears into the belt — same strength, same thickness, no metal. On the primaries, the overlands and the terminal belts that cannot stop, that is the only splice that belongs.
A splice failure usually has accomplices — a seized idler, a bare pulley, a cleaner that quit. We carry the parts and change them on the same visit.

About an hour to the San Gabriel Valley, downtown and the Gateway Cities from Fontana; up to two hours to the harbor and the San Fernando Valley. We answer 24/7 at (888) 480-0680 and roll with the press and belt on the truck.
Hot for heavy-duty, high-tension and critical belts — it is the strongest, longest-lasting splice. Cold for lighter belts and tight windows. Tell us the belt spec, tension and material and we will recommend one, and say so if a mechanical fastener is actually right.
Either. We stock 20,000+ feet in Fontana across common widths and grades, so most L.A. replacements ship from our shelf the same day. If you have belt on site, we will splice that.
Yes. We splice and replace terminal conveyor belts on schedules timed between vessels, with the badging, safety documentation and insurance certificates terminal operators require.
