A safety pin locking device for workpiece turnover includes a safety pin, a triangular lock plate, an elastic positioning pin, and a lockset. The safety pin is configured to be inserted into a base and an overturnable workpiece to lock an angle of the overturnable workpiece relative to the base. A first corner end of the triangular lock plate is connected to an axial surface of the safety pin by a fastener, and the triangular lock plate can rotate around the fastener. The elastic positioning pin is mounted at a second corner end of the triangular lock plate and is configured to be inserted into positioning counterbores at two different positions on the axial surface of the safety pin to limit a position of the triangular lock plate. The lockset is mounted at a third corner end of the triangular lock plate.

A bearing arrangement for a driver's cab of a lorry is disclosed. The bearing arrangement has a respective frame-side bracket which is fastened to a laterally associated frame element of a support frame of the lorry and which has a guide, along which an allocated bearing element of a driver's cab bearing can be displaced in the event of an accident-induced application of force. The bearing element is connected to the laterally allocated frame element of the support frame via a weakening device by which the laterally allocated frame element of the support frame can be weakened in a targeted manner in the event of an accident-induced displacement of the bearing element.

A cab tilting stay easy-unlock system includes: a tilting stay portion including an upper stay rod rotatably combined with a vehicle cab, a lower stay rod rotatably combined on an axis to the upper stay rod and rotatably combined with the vehicle body, and a locking handle provided at the upper stay rod and that fixes or unfixes the upper stay rod and the lower stay rod by being combined with the lower stay rod; and a tilting handle portion connected to the tilting stay portion by a cable and operating the tilting stay portion to be in a folded state.

A truck comprising a chassis, further comprising a front bumper, a cabin comprising a front lid, and a lock. The front lid is operable between an open position and a closed position, and the lock is operable between an unlocking configuration of the front lid and a locking configuration in which the front lid is locked in the closed position. The cabin is pivotally mounted on the chassis and is tiltable between a horizontal position and an inclined position. The truck comprises a latching mechanism, operable between an unlocking configuration of the cabin and a locking configuration in which the cabin is locked in the horizontal position, and an opening mechanism, mechanically connecting the latching mechanism to the lock and automatically operating the lock from its locking configuration to its unlocking configuration when the latching mechanism is operated from its locking configuration to its unlocking configuration.

A tilt locking apparatus for a truck cap is provided. The tilt locking apparatus includes a locking hook that is installed below the truck cap and a tilting lever that is installed under a lower portion of the truck cap to be rotatable. A hook lever is installed adjacent to the locking hook to be rotatable forward and rearward and is configured to rotate interlocking with the tilting lever to selectively lock or from the hook lever to or from the locking hook. A manipulation lever is installed adjacent to the tilting lever and forms a latch lever. The manipulation lever is configured to sequentially restrict rotation of the tilting lever and rotates so that when the tilting lever is sequentially released from the latch lever, the hook lever is removed from the locking hook.

A work machine comprises a main body, a cab riser, and a shaft. The cab riser includes a cab and a frame, the cab being uprightly positioned on the work machine in a first position, and being tilted forward in a second position, and the frame comprising a first plate to contact a second plate provided on the main body in the first position. The cab riser is rotatable about the shaft in clockwise and counterclockwise directions to and from the first position and the second position. The first plate and the second plate can be clamped together by a clamping assembly in the first position, the clamping assembly including one or more clamps to clamp the first plate and the second plate, and the clamping assembly is mounted on the main body.
