Boom lift machine

A boom lift machine comprising:

• a body;
• a boom defining a longitudinal axis;
• a mounting arrangement mounting the boom to the body;
• and
• a lifting unit extending between the boom and the mounting arrangement,
• wherein the boom is pivotably connected to the mounting arrangement at or proximate a first end of the boom,
• wherein the mounting arrangement is configured such that in response to actuation of the lifting unit, the boom is pivoted to raise or lower a second end thereof, and the boom is translated relative to the body,
• the boom lift machine further comprising a counterweight mass configured to counterbalance a tipping moment of the boom lift machine,
• wherein the counterweight mass is configured to translate with the boom,
• wherein the mounting arrangement forms part of a four bar linkage including:
• a first arm extending from a first pivot connected to the body to a second pivot connected to the boom;
• and
• a second arm extending from a third pivot connected to the body to a fourth pivot connected to the boom,
• wherein the first pivot is spaced from the third pivot and the second pivot is axially spaced from the fourth pivot along the boom,
• wherein the first pivot is spaced from the third pivot in the direction of a longitudinal axis of the body, and
• wherein the counterweight mass comprises a weight mounted to the boom at or proximate the first end thereof and pivotable about a pivot axis about which the boom is pivotably connected to the mounting arrangement.
