Problems solved by technology

However, the ROPS top cover is installed with optional specifications. Therefore, for the above-mentioned reasons, it is necessary to have stocks of ROPS top covers of different specifications for each model. Therefore, there is a problem that the total inventory of ROPS increases and the inventory management cost increases. question
In addition, in order to maintain an appropriate inventory of the unique ROPS top covers for each model, the number of production units (hereinafter referred to as production batches) of the unique ROPS top covers is extremely small, and thus there is a problem of high production costs.

Abstract

A ROPS canopy (50A) of a hydraulic shovel commonly usable among the models of different ranks, wherein a roof structure (40) is supported by two columns (31, 32) to form a basic ROPS canopy (50A) so that at least one of additional columns (51, 52, 53, 54, 55, 56) can be installed (50a, 50b, 50c, 50d, 50e, 50f) so as to match the ROPS canopies of higher class models. The additional columns (51, 52, 53, 54, 55, 56) are installable (57, 58b) by merely add-on method.

Description

technical field [0001] The invention relates to a ROPS top cover of a hydraulic excavator. Background technique [0002] In the small hydraulic excavators that are often used in urban civil engineering, since the work period at one work site is short, more attention is paid to the mobility between work sites. For this reason, light-weight and Easy to attach and detach, has a simple structure top cover with 2 pillars. However, in recent years, in order to ensure the safety of the driver when the vehicle is overturned, safety requirements have been increased in order to adapt to ROPS (Rollover Protective Structure), which is a unified strength standard such as that specified by ISO standards. [0003] In this case, the ROPS roof, as its name suggests, needs to have the strength to withstand when the vehicle is overturned (hereinafter referred to as overturning). Therefore, the strength of the main body of the roof and the strength of the members supporting the main body of th...
