Kato Crane Operators Manual

The ability to lift and slew a load is common to all cranes. Increasingly the need to lift a load up and over obstacles or up and on to the top of structures is in demand. People are probably familiar with the concept of luffing jibs on larger all terrain cranes, 200 tonnes plus. On smaller cranes operators have had to use manually fixed offsets to allow them to handle 'up and over' jobs. What is relatively new is the use of luffing jibs on smaller ATs and very recently on new RTs.

The hydraulic luffing jib concept on mobile cranes has its roots in East Asia. Asia has always been the place where hydraulic luffing jibs have been seen since the introduction of the mini rough terrain, or city crane, concept. It can be difficult and heavy work for operators to fit large manual swingaway jibs so this generated the need for the swingaway set up action and for the luffing jib to be powered. First examples were seen on Kobelco city cranes in the late 1980s and then on larger Kato and Tadano city cranes in the early 1990s.

Acceptance of the idea in the rest of the world began when the hydraulically powered swingaway set up action was removed while retaining the hydraulic luffing jib. Originally introduced on Krupp's KMK 3050, in 1994, and the KMK 2035, in 1995, the hydraulic luffing jib feature is now common across the Grove GMK range of all terrains. While it took a little while for it to become a major selling point, the use of the hydraulic luffer on five and six axle machines, in particular the GMK 5180 and GMK 6220, showed real performance advantages according to Grove. As operators got used to the benefits on the larger cranes they began to look for this feature on smaller all terrains. Demand has increased to the extent that Grove estimates that 85% of its machines now sold feature the hydraulic system as opposed to the manual.

In addition, there are bigger cranes that can carry loads of over 100 tons. The KA1300SL is a member of the lift family in question. This is a car-derived all-terrain crane. It has excellent responsiveness and speed. When combined with the vehicle, the unit weighs more than 90 tons. The maximum allowable weight of the lifted load is 130 tons. The crane can reach up to 75 km/h when traveling untethered on roads. It expands to a radius of roughly 10 m. The telescoping boom may extend to a maximum of 52 meters in length. The unit is standard equipment for building tall structures like skyscrapers.(adsbygoogle = window.adsbygoogle []).push();Other crane manuals (adsbygoogle = window.adsbygoogle []).push();Related Posts 041b061a72
