Benefits of technology

This patent describes an invention that provides a base plate for a housing with an outer housing plate and an inner gangway plate. An insulation layer can be added between these plates for noise reduction. Additionally, a mountable railing element can be added to increase safety on the sides or in the ceiling area. This railing element can have a folding or pivot mechanism and can provide additional protection for the working area. Overall, this invention improves the operational safety of the housing.

Problems solved by technology

However, such gangways arranged in a fixed manner either reduce the constructional space inside the housing or enlarge the external dimensions of the construction machine.
An external grating has a negative effect on the appearance of the upper carriage and is, moreover, exposed to dirt and soiling without protection.
The gangway can only be formed after the access wall has been opened which can be a problem in terms of handling and for the safety of the operating personnel.

Embodiment Construction

[0031]In FIGS. 1 and 2 an upper carriage 10 for a construction machine according to the invention is shown in a closed state, i.e. with closed access walls 30. The upper carriage 10 comprises a box-like housing 12 which is supported by a basic frame 14. The box-like housing 12 comprises side walls 20 which are closed at the top by a ceiling area 18. The side walls 20 have access walls 30 which can be opened and are described in greater detail hereinafter.

[0032]At a front side of the upper carriage 10 a driver's cab 16 is arranged, as is known for various kinds of construction machines, especially earth drilling apparatuses.

[0033]For the sake of clarity, the illustrated upper carriage 10 is shown to a large extent without any attachments. In a central area of the housing 12 rope winches and a mast can be mounted. Inside the housing 12 different types of drive and control components can be accommodated, in particular a diesel drive, hydraulic pumps and a substantial part of the machin...

Abstract

A construction machine comprising an undercarriage designed as a running gear and an upper carriage with a housing having side walls, wherein for access to the housing at least one housing opening with an access wall is provided, which is adjustable into an open position, and in an area in front of the housing opening a horizontal gangway is formed. At least one pull-out element is provided which can be pulled out horizontally between a retracted position and a pulled out position, in which the pull-out element projects horizontally from the housing, and in order to form the gangway a base plate is provided on the pull-out element.

Description

BACKGROUND OF THE INVENTION[0001](1) Field of the Invention:[0002]The invention relates to a construction machine comprising an undercarriage designed as a running gear an upper carriage with a housing having side walls, wherein for access to the housing at least one housing opening with an access wall is provided, which is adjustable by means of an adjustment mechanism into an open position, and in an area in front of the housing opening a horizontal gangway is formed.[0003](2) Description of the Related Art[0004]Upper carriages of such type are deployed, for example, in earth drilling apparatuses or other earth working machines. These construction machines usually have a running gear, in particular a crawler-track running gear, as an undercarriage, on which an upper carriage is arranged in a fixed or rotatable manner. The upper carriage can therefore have a considerable distance to the ground surface. Depending on the size of the undercarriage this can usually amount to 1 to 2 met...
