ACCESS DEVICE FOR WORK DEVICE
Document Type and Number:
Japanese Patent JP2023048130
Kind Code:
A
Abstract:
To provide an access device for a work device, which is for a movable crane in particular, which satisfies requirements in regard to a minimum dimension and can be easily and swiftly moved to a space-saving transportation orientation as well.SOLUTION: An access device 10 comprises a stringer 24, at least two steps 30 displaced in a transverse direction and longitudinal direction to each other and supported rotatably around a first rotational shaft 61 in the longitudinal direction to the stringer 24 respectively, and a guide bar 21 connecting the steps 30 to each other. The guide bar 21 is rotatably connected to each step 30 via a connection element 211 at an end of the step 30 opposite to the stringer 24, thus, the steps 30 can be moved together from an access orientation in which the steps 30 project in the transverse direction from the stringer 24 and users can walk on the access device 10 to a transportation orientation in which the steps 30 are placed on the stringer 24 around the first rotational shaft 61 and vice versa.SELECTED DRAWING: Figure 2
