Abstract: A battery module includes at least one cell assembly including a plurality of secondary batteries, a gas pipe configured to allow gas produced in a module housing to move therein, and the module housing including a lower case having one open side and an internal space in which the at least one cell assembly is received, and an upper case coupled to one side of the lower case to cover the one open side of the lower case and having a receiving space in which the gas pipe is received, and a connection hole to which one end of the gas pipe is connected such that the gas pipe and the internal space are in communication with each other.

Abstract: A forklift according to an exemplary embodiment of the present disclosure includes: a first hydraulic pump and a second hydraulic pump each of which generates a working fluid; a lift cylinder which raises or lowers a carriage; a first hydraulic line which supplies the working fluid from the first hydraulic pump to the lift cylinder and a second hydraulic line which supplies the working fluid from the second hydraulic pump to the lift cylinder; a first lift spool which controls the working fluid to be supplied to the lift cylinder through the first hydraulic line and a second lift spool which controls the working fluid to be supplied to the lift cylinder through the second hydraulic line; a first pilot line which transmits a pilot signal for operating the first lift spool and a second pilot line which transmits a pilot signal for operating the second lift spool; and an opening/closing valve which selectively closes any one of the first pilot line and the second pilot line.
