A vehicular steering device includes a turning shaft, a housing storing therein the turning shaft, a stopper provided at a shaft end of the turning shaft, and an annular elastic body. An opening of the housing is formed in a U-shaped cross-sectional shape and in an annular shape opened toward the stopper by an external cylinder portion and an internal cylinder portion. The elastic body includes a first elastic portion and a second elastic portion. The first elastic portion is supported by an inner circumferential surface of the external cylinder portion and the bottom surface, and is provided with a first clearance from an outer circumferential surface of the internal cylinder portion. The second elastic portion extends toward the stopper from the first elastic portion, and is provided with a second clearance larger than the first clearance from the inner circumferential surface of the external cylinder portion.

Disclosed is a shock absorption device including a dual fall prevention band connected to a safety rope connected to a safety harness that a worker wears. The shock absorption device including the dual fall prevention band includes a dual fall prevention band and a shock absorption band. The dual fall prevention band is shaped like a closed loop by coupling opposite ends thereof through a first seam, and the first ring, the second ring, a third ring, and a fourth ring are formed by coupling parts of the dual fall prevention band that face each other at a first position to each other through a second seam, and coupling parts of the dual fall prevention band that face each other at a second position to each other through a third seam.

Industrial truck, in particular a tri-lateral sideloader, comprising

a chassis (6),
a mast (8) arranged on the chassis (6),
a cab (12),
a support structure (9) supporting the cab (12), which can be moved up and down on the mast (8) together with the cab (12) and has at least one cantilever arrangement (24; 124) projecting from the mast (8), which arrangement extends underneath the cab (12) and supports a load-carrying assembly (36) arranged in front of the cab (12),
and a device for reducing vibrations having vibration components transverse to the main direction of travel (G) of the industrial truck, which device allows vibration-reducing movements of the load-carrying assembly (36) relative to the mast (8),
characterised in that
the cantilever arrangement (24; 124) has a division, having a first cantilever portion (50a; 150a), which is coupled to the mast (8) and guided thereon in a height-adjustable manner, as a first part, and having a second cantilever portion (50b; 150b), which supports the load-carrying assembly (36) and is connected to the first cantilever portion (50a; 150a), as the other part, such that, together with the load-carrying assembly (36), it can perform vibration-reducing movements relative to said first cantilever portion, in particular having movement components transverse to the main direction of travel (G) of the industrial truck.

Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cellular material formed of a three-dimensional interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow tube buckling, which is rendered repeatable by the micro-lattice architecture.
