Mobile rectangular lattice structure on wheels

The object is a tall, rectangular structure with a golden-brown finish, constructed from a lattice-like framework of what appears to be metal or wood. It stands on four wheels. Two horizontal bars span the top, supported by four vertical legs. Below these top bars are two shorter horizontal bars connected by a lower horizontal bar. Each horizontal bar is segmented into a larger left and smaller right section. A small, rectangular opening, possibly a window, is present on one side.
