A pallet includes a top deck and a bottom deck, and spaced apart support blocks coupled between the top and bottom decks and forming a gap therebetween for receiving a lifting member. Each support block includes a mid-section having spaced apart upper and lower surfaces, an upper tower extending from the upper surface of the mid-section, and a lower tower extending from the lower surface. The upper towers are inserted into corresponding upper tower openings in the top deck, and the lower towers are inserted into corresponding lower tower openings in the bottom deck.

The pallet according to claim 6 wherein said tubular section further comprises a biasing member, and wherein said insert comprises a catch that engages said biasing member. 8. The pallet according to claim 7 wherein the catch is configured as a groove within sidewalls of said insert, and wherein said biasing member comprises a spring that releases the groove at a predetermined load threshold. 9. The pallet according to claim 1 further comprising a plurality of tubular inserts carried by said top deck along outer edges thereof, each tubular insert butting up against at least one of said upper towers. 10. A plastic pallet comprising: a top deck having spaced apart upper and lower surfaces, with the lower surface having a plurality of upper tower openings recessed therein and a plurality of stepped upper projections projecting outwards therefrom, with each stepped upper projection adjacent a respective upper tower opening so as to form a top deck upper stepped interface;a bottom deck having spaced apart upper and lower surfaces, with the upper surface having a plurality of lower tower openings recessed therein and a plurality of stepped lower projections projecting outwards therefrom, with each stepped lower projection adjacent a respective lower tower opening so as to form a bottom deck lower stepped interface; anda plurality of spaced apart support blocks coupled between said top and bottom decks and forming a gap therebetween for receiving a lifting member, each support block comprising a mid-section having spaced apart upper and lower surfaces, and comprising first and second pairs of opposing exposed support block side surfaces, with each exposed support block side surface having a pocket formed therein for receiving an end of the lifting member so as to allow the pallet to be spun around,an upper tower extending from the upper surface of said mid-section, and with the upper surface having a stepped upper tower projection opening adjacent to and outwards from the upper tower so as to form a support block upper stepped interface,said upper tower inserted into a corresponding upper tower opening in said top deck, while the stepped upper tower projection opening receives a corresponding stepped upper tower projection from said top deck so that the top deck upper stepped interface contacts the support block upper stepped interface so as to provide a shear load transfer during impact with the lifting member,a lower tower extending from the lower surface, and with the lower surface having a stepped lower tower projection opening adjacent to and outwards from the lower tower so as to form a support block lower stepped interface, andsaid lower tower inserted into a corresponding lower tower opening in said bottom deck, while the stepped lower tower projection opening receives a corresponding stepped lower tower projection from said bottom deck so that the bottom deck lower stepped interface contacts the support block lower stepped interface so as to provide a shear load transfer during impact with the lifting member. 11. The plastic pallet according to claim 10 wherein said mid-section of each support block comprises a respective exposed support block corner surface extending between an exposed support block side surface in the first pair of exposed support block side surfaces and an adjacent exposed support block side surface in the second pair of exposed support block side surfaces. 12. The plastic pallet according to claim 10 further comprising a plurality of interlocking tower assemblies extending through said plurality of support blocks for coupling said top and bottom decks together, each interlocking tower assembly comprising: a tubular section carried by said bottom deck and having a flared end contacting the lower surface of said top deck; andan insert carried by said top deck and having a tapered end inserted into the flared end of said tubular section. 13.
