Trucks stop at the gate
A failed slide gate operator blocks every inbound and outbound trailer — your docks are idle even when every dock leveler and door is working perfectly.

Gate & Access
When the perimeter gate stops, everything behind it stops with it — trailers back up onto the street and your docks sit idle. InSev Tech repairs slide gate, swing gate, and barrier arm operators and services the access devices that control them: commercial access control — keypads, card readers, and telephone entry systems for facilities — plus loop detectors, and UL 325 safety sensors. Same-day dispatch, all major brands, written documentation.

UL 325 / ASTM F2200
Vehicular gate operators must have working entrapment protection and compliant gate construction. A bypassed photo eye is a documented liability at any industrial site.
One perimeter, one vendor
Commercial gate operators, barrier arms, and access control — keypads, card readers, and telephone entry systems for facilities — serviced by the same contractor that maintains your doors and docks — one call, one invoice.
Perimeter gates and access controls are usually the last thing on a facility's maintenance plan and the first thing that halts operations. A slide gate operator that has lost its limits, a barrier arm that won't lift, or a keypad that stopped reading codes will stop every truck and every employee at the property line.
InSev Tech services gates and access equipment as part of the same trade discipline as your commercial overhead doors and dock equipment — the same technicians, the same dispatch, and the same written reporting. That means one vendor for the door at dock position 12, the automatic entrance at the lobby, and the slide gate at the truck court.
Horizontal slide gates are the standard perimeter gate at Southern California distribution yards, truck courts, and manufacturing sites — and the operator takes the most abuse from cycle count, dust, and gate frame wear.
InSev Tech repairs slide gate operators of every drive type: chain-drive, rack-and-pinion, and hydraulic. Motor and gearbox replacement, drive chain and idler service, rack alignment, limit switch and encoder adjustment, and roller and track work at the gate frame itself.
Swing gate operators fail through arm linkage wear, hydraulic leaks, hinge post settling, and control board damage from irrigation water or power surges.
Arm and linkage replacement, hydraulic operator rebuild and seal service, hinge and post repair, and control board diagnostics — single-leaf and dual-leaf swing gates for industrial yards, employee lots, and secured equipment enclosures.
Barrier arms manage truck-court staging, employee parking, and guarded entry lanes. When the arm no longer lifts, drivers back up onto the street and your yard sequence breaks down.
Arm replacement, boom balance and spring adjustment, drive and clutch service, loop detector diagnostics, and integration with ticketing or guard-controlled systems.
Most gate calls turn out to be an access device, not the operator: a keypad that stopped reading codes, a card reader with a failed harness, a telephone entry unit that lost its line, or a corroded exit wand.
InSev Tech diagnoses and replaces commercial access control components — keypads, proximity and card readers, telephone entry panels, radio receivers, transmitters, and free-exit devices — and re-terminates the wiring back to the operator so the fix holds.
Vehicular gate operators are required to have working external entrapment protection — photo eyes, edge sensors, or a monitored equivalent. Facilities routinely find these bypassed after a nuisance-trip complaint.
Photo eye and edge sensor replacement, monitored-input restoration, reversing sensitivity testing, warning signage verification, and ASTM F2200 gate construction review — documented in a written report for your safety file.
Gate operators are the highest-cycle powered equipment on many industrial sites, running hundreds of cycles a day in dust and heat. Scheduled service is far cheaper than an emergency operator replacement.
Quarterly and semi-annual gate PM covering drive components, gate frame and track, safety device function testing, access device verification, and a written condition report — bundled with your door and dock PM program under one contract.
UL 325 is the safety standard covering door, gate, and barrier operators. For vehicular gates it requires external entrapment protection — photo eyes or edge sensors connected to monitored inputs — so the gate reverses instead of crushing a vehicle or a person.
ASTM F2200 covers the gate itself: no reach-through openings within reach of the operating controls, no pinch points at the leading edge, positive stops so the gate cannot leave its track, and compliant warning signage on both faces.
The most common finding at Southern California industrial sites is a photo eye that was disconnected or jumpered out after nuisance trips from dust, sun angle, or vibration. The gate keeps cycling, so nobody reports it — until an incident happens and the bypass is documented in the aftermath.
InSev Tech tests entrapment protection, restores monitored inputs, replaces failed sensors, verifies reversing behavior and signage, and issues a written report you can file next to your UL 325 and NFPA 80 door compliance documentation.

A commercial sliding gate would not open and the motor was suspected. On-site diagnosis found a failed main control board; the unit was replaced with a new LiftMaster operator, adjusted, tested, and approved by the customer.
