Haulotte to preview 23m boom at Intermat

Haulotte has revealed that it will be showing the prototype of a new rough-terrain telescopic boom, at Intermat. The HT23RTJ is a 23m working height machine designed through Haulotte's policy of close customer collaboration.

It is suitable for applications such as construction work, the shipbuilding industry, chemical and petrochemical industries, and the aviation industry.

Haulotte said that the machine offers the best performance in its class by combining the "best" working envelope, the "fastest" lifting speeds and "excellent" manoeuvrability.

The platform height is 22.4m, with an 18.1m outreach, the telescopic jib is 2.2m long and lifting capacity is 450kg. It takes the HT23RTJ 53 seconds to reach full height, which, Haulotte believes, can increase productivity threefold.

The HT23RTJ has a tight turning radius with 4 wheel steer and drive making it easy to operate on congested building sites and/or in tight spaces. There are3 steer settings: two-wheel steer, four wheel steer and crab, with centralised control, the four wheels are controlled simultaneously, allowing the steering movements to operate more quickly and safely.

The new telescopic boom has oscillating axles as standard for rough-terrain ability and has differential lock, and a narrow chassis which enable it to be operated in congested environments.

Haulotte said that particular attention has been paid to the rigidity of materials: the boom and the jib are made of high elastic modulus steel making them very stable and safe to operate. Similarly the capacity of hydraulic circuit has been optimised to give the operator maximum control in safely and comfort.

The cables, which actuate the extension of the boom have been designed in such as way as to allow their replacement without dismantling the boom. This is among the features designed to improve the ease of maintenance as is the new fully modular basket which is easy and cost effective to repair.

The new boom will be available from October 2012 in Europe and North America.
