Abstract
Abstract A movable lifting and depositing device comprising separate rack and pinion jacks to be connected to the corners of portable containers, e.g., cabins, containers, shelters or the like, by means of brackets, the jacks having racks for the containers provided on columns which have track wheels at the bottom. In order to maintain sufficient stability of the lifting and depositing device, even when the container to be handled is at relatively high positions, each rack and pinion jack has a swivel mechanism with two vertically spaced work positions. In its bottom work position, wherein it is folded down from a main column guide onto a relevant bracket, the swivel mechanism is to be connected with an auxiliary column guide arranged beneath the main column guide. This can be moved by the swivel mechanism into the top work position of the associated column. To move the swivel mechanism into one of the two work positions when it is loaded, a stop device is provided between the main column guide and the associated rack or column.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
203 words
A movable lifting and depositing device for portable containers, e.g., cabins, containers, shelters or the like, with rack and pinion jacks connected by means of brackets to the corners of the containers, the jacks having racks for the containers which are provided on movable columns having track wheels, the columns being raised for depositing of the container, e.g., on the ground, or for lifting of the wheels by the rack and pinion jacks to the level of the container bottom, characterized in that: (a) each rack and pinion jack (13) has a swivel mechanism (18) with two vertically spaced work positions; (b) the swivel mechanism (18) in its bottom work position, being folded down from a main column guide (16) onto the associated bracket (10), for connection with an auxiliary column guide (33) arranged beneath the main column guide (16), which can be removed when the swivel mechanism (18) of the associated column support (14) is in the top work position; and (c) stop means (29) between the main column guide (16) and the associated rack (17) and column (14) to enable movement of the swivel mechanism (18) into one of said two work positions when the lifting and depositing device is loaded.
Claim 2
Dependent Claim
203 words
A movable lifting and depositing device for portable containers, e.g., cabins, containers, shelters or the like, with rack and pinion jacks connected by means of brackets to the corners of the containers, the jacks having racks for the containers which are provided on movable columns having track wheels, the columns being raised for depositing of the container, e.g., on the ground, or for lifting of the wheels by the rack and pinion jacks to the level of the container bottom, characterized in that: (a) each rack and pinion jack (13) has a swivel mechanism (18) with two vertically spaced work positions; (b) the swivel mechanism (18) in its bottom work position, being folded down from a main column guide (16) onto the associated bracket (10), for connection with an auxiliary column guide (33) arranged beneath the main column guide (16), which can be removed when the swivel mechanism (18) of the associated column support (14) is in the top work position; and (c) stop means (29) between the main column guide (16) and the associated rack (17) and column (14) to enable movement of the swivel mechanism (18) into one of said two work positions when the lifting and depositing device is loaded.
Claim 3
Dependent Claim
28 words
The device as in claim 1, characterized in that the swivel mechanism (18) is mounted at the bottom end of main column guide (16) near its outside edge.
Claim 4
Dependent Claim
31 words
The device as in claim 1 or 2, characterized in that the two work positions of the swivel mechanism (18) are offset from each other at an angle of substantially 180°.
Claim 5
Dependent Claim
46 words
The device as in claim 1 or 2, characterized in that swivel mechanism (18) has driving pinions (23, 24) on facing sides which, according to the work position of the swivel mechanism (18), are alternately in engagement with the rack (17) of the associated column (14).
Claim 6
Dependent Claim
35 words
The device as in claim 1, characterized in that an auxiliary column guide (33) is mounted to swivel on the bottom end of the associated bracket (10), which also supports the main column guide (16).
Claim 7
Dependent Claim

Claim 8
Dependent Claim
37 words
The device as in claim 1, characterized in that an auxiliary column guide (33A) is connected to the swivel mechanism (18), and means are provided to connect detachably the auxiliary column guide with the associated bracket (10).
Claim 9
Dependent Claim
43 words
The device as in claim 6, characterized in that on the side of each auxiliary column guide (33) are mounted spring arms (38, 39), which, when auxiliary column guide (33) is in the work position, are connected in contact with the container (12).
Claim 10
Dependent Claim
37 words
The device as in claim 6, characterized in that each auxiliary column guide (33) when in its work position is connected by at least one strut (47) with a stabilizing part (45) angularly surrounding the container corner.
Claim 11
Dependent Claim
56 words
The device as in claim 7, characterized in that the auxiliary column guide (33B) is mounted to swivel at the top end of the associated bracket (10), whereby when swivel mechanism (18) is folded up by connection with the bracket (10), it can serve as guide for column (14) and can stabilize the main column guide.
