In a vehicle having a wheel or endless track driven undercarriage supporting a lifting arm, the undercarriage (10) of the vehicle is provided with formations (20) on a vertical lateral surface (18) to engage with mating formations (22) on a vertical lateral surface of a removable counterweight (16). The formations (20,22) are shaped to engage by sliding the counterweight (16) in a vertical plane relative to the undercarriage (10) and, when engaged, they support the weight of the counterweight (16) vertically and prevent separation of the counterweight (16) from the undercarriage (10). |
