1. A carriage lift assembly comprising:
at least one frame element configured to secure the carriage lift assembly relative to a first mast and a second mast, the first mast and the second mast being spaced a lateral distance apart, wherein the carriage lift assembly is defined at least in part by a lift width that extends along at least a portion of the lateral distance between the first mast and the second mast;
at least one spreader arm defined at least in part by a spreader arm width extending laterally between a first frame end of the at least one frame element and a second frame end of the at least one frame element, wherein the spreader arm width defines at least a portion of the lift width of the carriage lift assembly;
a load surface configured to support one or more objects disposed thereon;
wherein the spreader arm width of the at least one spreader arm comprises a selectively adjustable configuration, wherein the lift width of the carriage lift assembly is configured to be selectively adjustable based at least in part on the selectively adjustable configuration of the spreader arm width and wherein the at least one spreader arm comprises a first arm element and a second arm element arranged in an at least partially telescoping configuration defined by an axial range of relative motion between the first arm element and the second arm element, wherein the selectively adjustable configuration of the spreader arm width of the at least one spreader arm is based at least in part on the axial range of relative motion between the first arm element and the second arm element and wherein the at least one spreader arm is configured to enable a relative motion between the first arm element and the second arm element in each of a vertical direction, a lateral direction, a longitudinal direction, and an angular direction; and
at least one spring elements configured to apply a lateral force on at least one of the first arm element and the second arm element in order to facilitate an axial relative motion between the first arm element and the second arm element.
