Air-Activated Dock Levelers

The Serco Air Bag Dock Leveler utilizes advanced air lifting technology to provide a cost-effective solution for the loading dock. Simple operation and a clean, efficient design provides a level of performance unequalled in the industry. The leveler is activated by a simple push button located on the loading dock wall. Pushing the button activates the two-stage, single-speed fan, which inflates the air bag and raises the deck and lip. Releasing the button allows the deck to descend to the truck bed. The Air Bag Dock Leveler does not incorporate a high maintenance hold down and springs like mechanical levelers. Compared to mechanicals, Air Bag Dock Levelers are superior in operational efficiency and deliver a lower total cost of ownership.

Standard Features

• High volume, low pressure air bag lifting mechanism — requires no scheduled maintenance

• Push-button activation system

• Automatic lip extension with every cycle

• Solid steel safety stop legs — manual retracting for below dock operations

A hydraulic, pit-mounted, retractable restraint system, the SLP 2000 is ideally suited for new construction applications. In colder northern climates, the retracted hook is protected from snow and ice build-up, which can impede the operation of some externally mounted restraints. This also means no obstruction to (or accidental damage from) snow removal equipment or ground-level forklift to dock height operations.

When activated, the Serco SLP extends its restraining arm from the pit under hydraulic power at a height which allows access to lower rear impact guards (approximately 8") not accessible by other systems. The restraining arm moves vertically - up to 30" - controlled by a programmable controller to sense positive engagement of the rear impact guard. If no rear impact guard contact is made, the SLP automatically restores itself and signals the dock attendant by flashing an amber warning light on the control panel. Once the hook is successfully engaged, the SLP restraint floats with the vertical movement of the trailer, maintaining positive engagement with the rear impact guard throughout the loading and unloading process. When stored, the restraint retracts fully into the dock face.

Once the hook is successfully engaged, the restraining arm automatically follows the vertical movement of the rear impact guard as the trailer is loaded or unloaded, maintaining positive engagement throughout the loading and unloading process.
