1. A hydraulically actuated skate system comprising:
- a movable platform,wherein the movable platform comprises a plurality of channels on an underside of the movable platform, andwherein each channel has open ends and extends an entire length of the movable platform; and
a hydraulically actuated skate comprising;
a platform;
a plurality of tines coupled to the platform,wherein a length of each tine is greater than or equal to the entire length of the movable platform,wherein a width of each tine is less than or equal to a width of each channel,wherein each tine comprises;
an upper channel having a plurality of ramp assemblies; and
a lower channel having a plurality of rollers and ramp rollers,wherein the lower channel is slidingly received with the upper channel; and
a hydraulic assembly coupled to each tine, wherein actuation of the hydraulic assembly causes the ramp rollers to roll along the ramp assemblies, causing expansion of each tine from a first height to a second height,wherein the upper channel has an open-ended rectangular cross-section and the lower channel has an inverted open-ended rectangular cross-section relative to the upper channel,wherein an upper edge of sidewalls of the lower channel are bent outward to form an outward extending shelf which is curved, andwherein a lower portion of interior sidewalls of the upper channel comprise a plurality of periodically spaced inward extending locking elements.

Abstract
The present invention provides a movable platform (MP) having a simple construction that is capable of being conveyed by a hydraulically actuated skate system (HASS). The MP is able to accommodate freight placed upon its surface and can be used to fully load a trailer in a single cross-dock move. The HASS can be used to move the MP during cross-dock operations. The HASS comprises a plurality of tines which are received in corresponding support channels in the MP. The tines are used to lift the MP off the ground and rollers on the tines can be used to move the MP. A conveyance vehicle is used to move the HASS and the MP after the tines have been actuated.
