Abstract
A dockleveler comprising a support structure, a ramp connected to the support structure and movable between raised and lowered positions, a upward biasing mechanism connected to the ramp, and a holdown mechanism connected between the ramp and the support structure. The holdown mechanism includes a spring assembly having an extension spring that increases in length as the ramp moves toward the raised position. The holdown mechanism further includes an adapter member interconnecting the holdown mechanism with at least one of the ramp and the support structure. The adapter member is separable from the holdown mechanism to allow the attachment of different adapter members to the holdown mechanism without cutting or welding. The extension spring is housed within a first hollow member and a second hollow member positioned at least partially within the first hollow member and movable relative to the first hollow member.
