When the workbench is in the unfolded state, the lower end of the handrail 400 is inserted into the corresponding installation hole, and the plurality of handrails 400 form a fence to protect the staff. When the work platform needs to be folded, the handrails 400 need to be removed to form as Figure 2The folded state shown.

[0042] For the foldable working platform in the above technical solution, when the roadheader needs to turn during operation in a narrow roadway, the working platforms on both sides can be folded up to facilitate the smooth passage of the roadheader.
