A system comprising a tool handling system for transporting a sealing tool, the tool handling system comprising: a trolley comprising a vertical height adjustment member operable to move between a first position and a second position; and a support table for supporting a sealing tool, said support table comprising a first attachment member (34a, 34b) complimentary to said vertical height adjustment member, wherein the trolley is arranged to receive the support table in an attachment position that aligns the first attachment member (34a, 34b) with the vertical height adjustment member, such that when the vertical height adjustment member is moved from the first position to the second position, the first attachment member engages (34a, 34b) with the vertical height adjustment member and the support table attaches to the trolley and, in use, is raised off of the floor, and a traysealing machine, the traysealing machine comprising: a frame and a platform (14a, 14b) arranged to support a sealing tool, wherein the platform (14a, 14b) is mounted to the frame such that said platform (14a, 14b) is moveable relative to the frame between a sealing position where the sealing tool is operable to seal containers, and a maintenance position providing clearance between the sealing tool and the top of the traysealing machine, wherein the support table is arranged to cooperate with the traysealing machine such that, in use, when the platform (14a, 14b) is in the maintenance position, the sealing tool can be transferred from the traysealing machine to the support table by movement of the vertical height adjustment member from the first position to the second position such that the support table is raised off of the floor, lifting the sealing tool off of the platform (14a, 14b) and on to the support table. a trolley comprising a vertical height adjustment member operable to move between a first position and a second position; and a support table for supporting a sealing tool, said support table comprising a first attachment member (34a, 34b) complimentary to said vertical height adjustment member, wherein the trolley is arranged to receive the support table in an attachment position that aligns the first attachment member (34a, 34b) with the vertical height adjustment member, such that when the vertical height adjustment member is moved from the first position to the second position, the first attachment member engages (34a, 34b) with the vertical height adjustment member and the support table attaches to the trolley and, in use, is raised off of the floor, and a traysealing machine, the traysealing machine comprising: a frame and a platform (14a, 14b) arranged to support a sealing tool, wherein the platform (14a, 14b) is mounted to the frame such that said platform (14a, 14b) is moveable relative to the frame between a sealing position where the sealing tool is operable to seal containers, and a maintenance position providing clearance between the sealing tool and the top of the traysealing machine, wherein the support table is arranged to cooperate with the traysealing machine such that, in use, when the platform (14a, 14b) is in the maintenance position, the sealing tool can be transferred from the traysealing machine to the support table by movement of the vertical height adjustment member from the first position to the second position such that the support table is raised off of the floor, lifting the sealing tool off of the platform (14a, 14b) and on to the support table. a support table for supporting a sealing tool, said support table comprising a first attachment member (34a, 34b) complimentary to said vertical height adjustment member, wherein the trolley is arranged to receive the support table in an attachment position that aligns the first attachment member (34a, 34b) with the vertical height adjustment member, such that when the vertical height adjustment member is moved from the first position to the second position, the first attachment member engages (34a, 34b) with the vertical height adjustment member and the support table attaches to the trolley and, in use, is raised off of the floor, and a traysealing machine, the traysealing machine comprising: a frame and a platform (14a, 14b) arranged to support a sealing tool, wherein the platform (14a, 14b) is mounted to the frame such that said platform (14a, 14b) is moveable relative to the frame between a sealing position where the sealing tool is operable to seal containers, and a maintenance position providing clearance between the sealing tool and the top of the traysealing machine, a frame and a platform (14a, 14b) arranged to support a sealing tool, wherein the platform (14a, 14b) is mounted to the frame such that said platform (14a, 14b) is moveable relative to the frame between a sealing position where the sealing tool is operable to seal containers, and a maintenance position providing clearance between the sealing tool and the top of the traysealing machine, wherein the support table is arranged to cooperate with the traysealing machine such that, in use, when the platform (14a, 14b) is in the maintenance position, the sealing tool can be transferred from the traysealing machine to the support table by movement of the vertical height adjustment member from the first position to the second position such that the support table is raised off of the floor, lifting the sealing tool off of the platform (14a, 14b) and on to the support table.
