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, and wherein 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, and wherein a width of each tine is less than or equal to a width of each channel; and a hydraulic assembly coupled to each tine, characterised in that: each tine comprises: an upper channel having a plurality of ramp assemblies; and a lower channel having a plurality of rollers and ramp rollers, the dimensions of the upper channel being slightly larger than that of the lower channel, wherein the lower channel is slidingly received with the upper channel, 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, wherein an upper portion of each sidewall of the lower channel is bent outwards from said sidewall to form an outward extending shelf on each side of the lower channel, wherein a lower portion of interior sidewalls of the upper channel comprises periodically spaced inward extending locking elements, and wherein engagement of the outward extending shelf of the lower channel with the inward extending locking elements of the upper channel prevents further expansion of the upper channel and lower channel during actuation of the tines, thereby preventing separation of the upper channel from the lower channel. a movable platform, wherein the movable platform comprises a plurality of channels on an underside of the movable platform, and wherein each channel has open ends and extends an entire length of the movable platform; and wherein the movable platform comprises a plurality of channels on an underside of the movable platform, and wherein 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, and wherein a width of each tine is less than or equal to a width of each channel; and a hydraulic assembly coupled to each tine, 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, and wherein a width of each tine is less than or equal to a width of each channel; and a hydraulic assembly coupled to each tine, characterised in that: each tine comprises: an upper channel having a plurality of ramp assemblies; and a lower channel having a plurality of rollers and ramp rollers, the dimensions of the upper channel being slightly larger than that of the lower channel, wherein the lower channel is slidingly received with the upper channel, 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, wherein an upper portion of each sidewall of the lower channel is bent outwards from said sidewall to form an outward extending shelf on each side of the lower channel, wherein a lower portion of interior sidewalls of the upper channel comprises periodically spaced inward extending locking elements, and wherein engagement of the outward extending shelf of the lower channel with the inward extending locking elements of the upper channel prevents further expansion of the upper channel and lower channel during actuation of the tines, thereby preventing separation of the upper channel from the lower channel. each tine comprises: an upper channel having a plurality of ramp assemblies; and a lower channel having a plurality of rollers and ramp rollers, the dimensions of the upper channel being slightly larger than that of the lower channel, wherein the lower channel is slidingly received with the upper channel, an upper channel having a plurality of ramp assemblies; and a lower channel having a plurality of rollers and ramp rollers, the dimensions of the upper channel being slightly larger than that of the lower channel, wherein the lower channel is slidingly received with the upper channel, 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, wherein an upper portion of each sidewall of the lower channel is bent outwards from said sidewall to form an outward extending shelf on each side of the lower channel, wherein a lower portion of interior sidewalls of the upper channel comprises periodically spaced inward extending locking elements, and wherein engagement of the outward extending shelf of the lower channel with the inward extending locking elements of the upper channel prevents further expansion of the upper channel and lower channel during actuation of the tines, thereby preventing separation of the upper channel from the lower channel.
