The present invention relates to a forklift capable of mounting a door in a state in which a pipe for forming a cabin frame is not drilled, the forklift having: a door mounting bar, which is mounted on the outer surfaces of rear pipes at both left and right surfaces of the cabin frame of the forklift, has a bent part formed at the upper end thereof, and has a fastening part formed on one side surface thereof by bending so as to be positioned at the rear surface of the rear pipe; a rear window frame which is mounted between both the left and right rear pipes at the rear of the cabin frame and is formed as a square frame having, at both the left and right sides thereof, engagement fastening parts coupled to the fastening part of the door mounting bar; connecting brackets which simultaneously fasten the door mounting bar and the rear window frame while coming in close contact with the rear pipe at the inner side of the cabin frame; and a hinge bracket which is provided at the upper and lower ends of the outer surface of the door mounting bar, is integrally provided with threads so as to ensure the thread thickness of bolt fastening for the assembly of a hinge for opening and closing the door, and has a predetermined thickness.

A pallet sled includes a base and a pair of tines extending from the base. A load wheel supports outer ends of each of the tines. A wheel supports the base. At least one motor is configured to drive the base wheel or at least one of the load wheels for driving the pallet sled. The motor may be a hub motor inside the base wheel or the load wheel.

A riding lawn mower comprising, a pair of rear drive wheels, a pair of front wheels, a deck positioned between the pair of front wheels and the pair of rear drive wheels, a rotatable cutting blade, and multiple battery packs removably coupled to the riding lawn mower and structured to provide power to the riding lawn mower, each battery pack graspable and removable by a user, wherein the multiple battery packs jointly provide power to the riding lawn mower.

An air spring actuated slider pin release system for a semi-trailer slider includes an actuator shaft oriented to extend in generally parallel relationship to at least one of a pair of parallel main members, being connected to the slider for axial rotation, and having a transverse lever arm secured to each end of the shaft for common rotation. Each lever arm has an end connected to a retractable, biased lock pin via a link so that rotation of the shaft and the lever arms causes retraction of the associated lock pin relative to the main member. The actuator shaft has a normally projecting air spring bracket. An air spring is disposed between one of the main members and the air spring bracket so that inflation of the air spring acts on the air spring bracket, axially rotating the shaft and the lever arms for retracting the lock pins.

A high-pressure hydrogen container is provided that has a simple configuration, requiring less labor for manufacture, achieving reduced manufacturing costs, and ensuring pressure resistance. The high-pressure hydrogen container includes a metal cylinder configured to store high-pressure hydrogen, a pair of lid parts configured to cover both end portions of the metal cylinder, and a plurality of fastening parts configured to fix the pair of lid parts in a state where the metal cylinder is clamped between the pair of lid parts.
