Abstract
A crane for mounting to a vehicle, comprising a base defining a plane, a column member pivotally connected with respect to the base at a first end, and a column lifting arrangement, configured to adjust an angle of the column member with respect to the plane, wherein the column member is configured to be moved between a retracted position, where the column member lies substantially parallel with the plane defined by the base, through to a fully extended position, where the angle between the column member and the plane defined by the base is greater than 90 degrees.
Claims17
A crane for mounting to a vehicle, comprising:
- a base defining a plane;
- a column member pivotally connected with respect to the base at a first end;
- and
- a column lifting arrangement, configured to adjust an angle of the column member with respect to the plane,
- wherein the column member is configured to be moved between a retracted position, where the column member lies substantially parallel with the plane defined by the base, through to a fully extended position, where the angle between the column member and the plane defined by the base is greater than 90 degrees.
The crane as claimed in any one of the preceding claims, wherein the column lifting arrangement comprises a pair of hydraulic column cylinders pivotally connected at their first ends with respect to the base about an axis parallel to and spaced apart from that about which the column is pivotally connected with respect to the base, and pivotally connected at their second ends with respect to the second end of the column member, such that extension of the column cylinders causes an increase in the angle between the column member and the plane, and retraction of the column cylinders causes a decrease in the angle between the column member and the plane.
The crane as claimed in any one of the preceding claims, further comprising a boom member pivotally connected with respect to the column member at its second end, and a boom lifting arrangement, configured to adjust an angle of the boom member with respect to the column member.
A crane for mounting to a vehicle, the crane comprising:
- a base defining a plane;
- a column member pivotally connected with respect to the base at a first end;
- a boom member pivotally connected with respect to the column at a second end;
- a column lifting arrangement, configured to adjust an angle of the column member with respect to the plane;
- and
- a boom lifting arrangement, configured to adjust an angle of the boom member with respect to the column member,
- wherein the crane is able to be moved between a collapsed configuration, where the column member lies substantially parallel with the plane defined by the base and the boom member lies substantially parallel with the column member through to a range of operational configurations where the angle between the column member and the plane defined by the base is anywhere between approximately 0 and 100 degrees and the angle between the boom member and column member is anywhere between approximately 0 and 85 degrees.
A vehicle comprising a body and a crane as claimed in any one of the preceding claims, mounted to the body or the vehicle.
