Abstract: The present invention relates to a guardrail for construction equipment. More specifically, the present invention relates to a guardrail for construction equipment that can adjust the overall height thereof, for example, to satisfy a height limit when a cargo ship is loaded with construction equipment, thereby increasing the amount of loaded construction equipment to reduce a transportation cost. To this end, the present invention provides a guardrail for construction equipment, comprising: a lower guardrail fixed to the edge of an upper body of the construction equipment; an upper guardrail connected to the lower guardrail; and a connecting part that is formed between the lower and upper guardrails to connect the lower and upper guardrails and enables the upper guardrail to move toward the lower guardrail, thereby adjusting the overall height made by the lower and upper guardrails.

Abstract: A door hinge assembly is provided which can prevent the phenomenon of closure of an open door by performing a self-stay function, and can improve a worker's or user's convenience and implement a cost saving effect by simplifying the configuration compared to the prior art in which a hinge and a stay are separately provided.
