Cantilever gate hardware that holds long leaves straight

Cantilever Gate Hardware is what holds a CAIMEN leaf in the air. Carriages, rollers, pull rods, brackets: the beam rides on all of them, and if they're wrong, even a good beam will sag, rub or wander off line. When they're right, the leaf rolls smoothly and stays aligned over repeated cycles.

You won't find us selling these parts as loose catalog items picked by guesswork. They ship as part of a complete aluminum cantilever gate, built around one of our four 6005-T6 aluminum beam profiles. Which profile? That depends on gate length, height, infill design and structural load.

12-wheel multi-directional carriage

Every carriage grips the beam from three directions, with top, bottom and side rollers. Why bother? Three forces act on a hanging leaf. The bottom wheels take its weight. Up top, a second set keeps the tail from lifting, while the side rollers stop a crosswind from pushing the leaf off line.

Precision bearings and heavy-duty rollers

Precision bearings in heavy-duty rollers cut rolling resistance. Less drag means less work for the drive on each cycle, and you'd feel that most on a long leaf opening dozens of times a shift. It also eases the load on the 500 W drive, while the VFD handles soft start and stop.

Stainless steel pull-rod bracket and cast steel pull rods

Long spans like to droop at the nose. To fight that, a stainless steel pull-rod bracket ties into the frame and a heavy-duty cast steel pull-rod system adds tension, resisting deformation under load and keeping the leaf aligned across the span. At the receiving end, our engineering documentation also lists a cast steel joint base, a stainless steel door guide and a heavy-duty guide wheel.

Serviceable, bolt-together parts

Nothing here needs heavy site welding. The structure uses modular bolt-together connections, so if one roller wears, your crew swaps that roller and moves on. Carriage, roller and reinforcement parts can each be adjusted or replaced on their own.

Use it wherever a trackless leaf has to stay true across a wide opening. Typical spots:

• Factory and logistics yards, where trucks cross the driveway and there's no ground rail to clog or crack.
• Uneven ground, drainage channels, drifting sand, heavy snow. A track would fail first in any of these.
• Commercial and residential entrances wanting a clean threshold and a quiet, steady roll.
• Coastal or windy sites. For these, our installation manual suggests custom reinforcement: a larger bottom beam, extra embedded parts, double-side diagonal pull rods and a bigger motor.

Say your 6 m clear opening sits right next to a parking lane. That job won't look like a 4 m residential drive, and it shouldn't be specified like one.

Start with the beam, not the wheels. We choose from four 6005-T6 profiles based on gate length, height, infill design and structural load. The biggest bottom beam measures 302 x 213 mm with walls up to 7.0 mm, and the top beam is 113 x 93 mm with 2 to 6 mm walls.

People underrate wheel heights. Don't. Our installation manual wants the motor cabinet, gate frame and hanger wheels on the same plane within plus or minus 10 mm, with the rear hanger wheel about 1.5 cm lower than the front cabinet support wheel so the lever action keeps the nose up. Ground clearance runs 110 to 133 mm, depending on the model. The installation manual specifies an 800 x 800 x 800 mm foundation pit in concrete no lower than C20; you'll find the full sequence in our installation guide.

See the pattern? Total length is 1.5 times the opening, and that extra half gives the counterbalance tail its room. Writing a spec around ASTM F1184? It's the industry standard describing horizontal slide gates, cantilever type included, so it makes a good checklist of what to ask. It isn't a certification we claim.
