You asked for it, you got it
At its recent Customer Days at its Ehingen (Germany) hydraulic boom crane factory, Liebherr unveiled a 220t capacity LTR 1220 hydraulic boom crawler crane.
Until now the largest crane of this type on the Liebherr range has been 100t capacity LTR 1100, of which there are a number working in Australia. Until relatively recently the market for hydraulic boom crawler cranes, not just in Australia but around the world, had been largely ignored although a 16t Kato hydraulic boom crawler crane was popular in Australia in the 1970s and many lamented its demise.
Although there has been market demand for a hydraulic boom crawler crane with more than 100t capacity, manufacturers until now have largely worked to fill, if not overfill, the market with cranes below 100t in capacity.
Liebherr is in an excellent position to built larger cranes, being the world’s largest manufacturer of hydraulic boom all terrain cranes as well as a significant manufacturer of lattice boom crawler cranes. The 60m boom for the LTR 1220 is derived from an all terrain crane of the same capacity.
This crane can be fitted with a lattice boom extension, a swing-away jib, and an erection jib and second winch for turning a load such as a panel.
There are a number of circumstances where a hydraulic boom crawler crane would be preferable to a lattice boom crawler crane or an all terrain crane. Reasons for using tracks include poor ground conditions in the access to the lift area and the ability to walk with a load (care in ground preparation as well as operation is required when walking a load, to avoid side load on the boom).
Reasons for using a telescopic boom rather than a lattice boom include speed of set-up and pull-down for short-term jobs, ease of transport and the ability to readily vary the boom length as required. This can be important where there are head height issues or where being able to telescope the boom under load is an advantage if the load is placed at a different radius to what it is picked up at.
A hydraulic crane can be an advantage when road or track access is only allowed for restricted hours so a fast set-up and pull-down time maximises actual lifting time.
