Dock Levelers & Loading Dock Equipment

A dock leveler that won't rise or a restraint that won't release stops the whole dock. We install and service the equipment that keeps trailers loading.

Dock Levelers & Loading Dock Equipment in Sacramento & Northern California

The loading dock is where a warehouse actually makes money, and the leveler is the piece of equipment forklifts drive across a few hundred times a shift. Mechanical levelers use springs and a pull chain; hydraulic levelers use a pump and cylinders with push-button controls; air-powered levelers use an airbag; edge-of-dock levelers handle smaller height differences on a budget. Around the leveler sit the bumpers that protect the wall, the seals and shelters that close the gap around the trailer, and the vehicle restraints that keep the trailer from creeping away while the forklift is inside.

Guardian Door LLC installs, repairs, replaces, and maintains dock levelers and loading dock equipment across Sacramento and Northern California for distribution centers, manufacturers, cold storage, retail distribution, and food and beverage facilities. We service leveler springs, lips, hinges, hold-downs, hydraulic pumps, cylinders, and hoses, controls and control panels, dock bumpers, dock seals and shelters, vehicle restraints, and dock lights and communication systems.

How Dock Levelers & Dock Equipment Works

What to expect from the first call through the finished opening.

  1. 1

    Dock inspection

    We inspect the leveler platform, lip, hinges, springs or hydraulics, pit condition, bumpers, seals, and restraints, and identify any safety issues.

  2. 2

    Repair or replacement pricing

    You get a written price for the repair and, where the leveler is worn out, for a replacement leveler matched to the pit and capacity.

  3. 3

    Repair work

    Springs, lips, hinges, hold-downs, pumps, cylinders, hoses, controls, bumpers, seals, and restraint components are replaced.

  4. 4

    Leveler installation

    Replacement levelers are set in the existing pit or a new pit, welded or anchored, wired, and adjusted to the dock height.

  5. 5

    Operation and safety check

    Every leveler is cycled through full range, lip extension verified, and restraints and controls tested before the dock goes back in service.
