Ef­fi­cient LRS 545 Log Han­dler

So­phis­ti­cated de­sign and proven qual­ity stan­dards make the new Lieb­herr LRS 545 Log Han­dler a hall­mark of re­li­a­bil­ity. With up to 30 tonnes lift­ing ca­pac­ity and a max­i­mum grap­ple ca­pac­ity of 8.2 m², the new Log Han­dler from Lieb­herr sets stan­dards when it comes to tim­ber han­dling per­for­mance. The tele­scopic boom al­lows an un­ri­valled range of up to 8.5 me­tres and stack­ing height of up to 8.9 me­tres. An­other ad­van­tage is the pos­si­bil­ity of log han­dling be­low ground level.

Ever since the mar­ket launch in June 2015, all the de­vices of the LRS 545 se­ries have been among the most in­no­va­tive ones on the reach­stacker mar­ket. The de­ci­sive fac­tor above all is the unique drive con­cept of the Lieb­herr reach­stack­ers, the hy­dro­static drive. This con­cept is a high-end so­lu­tion de­vel­oped by Lieb­herr and has al­ready proven it­self in over 70,000 Lieb­herr wheel load­ers. It en­ables a num­ber of unique ad­van­tages over com­pet­i­tive prod­ucts, e.g. main­te­nance- and wear-in­ten­sive parts such as dif­fer­en­tial and torque con­vert­ers can be saved. Fur­ther­more, the hy­dro­static drive com­bined with the ex­tremely eco­nom­i­cal 230 kw Lieb­herr diesel en­gine pro­vides pos­si­ble fuel sav­ings of up to 30% com­pared to the mar­ket av­er­age.

To ex­tend the safety as­pect dur­ing op­er­a­tion, Lieb­herr de­vel­oped the new Topview Cam­era Sys­tem, which is an op­tional fea­ture avail­able for all de­vice types of the LRS 545 se­ries. The in­no­va­tive Topview Sys­tem of­fers the driver an ex­cel­lent rear and side view from a bird’s eye per­spec­tive, without any blind spots. Due to the log­i­cal com­po­si­tion of three cam­era im­ages, the com­plete rear area is cov­ered by the sys­tem at an an­gle of 270°.

The new LPS 420 E

The new LPS 420 E is the lat­est ex­ten­sion of the Lieb­herr mo­bile har­bour crane prod­uct range. The newly de­signed ma­chine is a purely elec­tric driven por­tal crane. All crane move­ments like luff­ing, hoist­ing, slew­ing and trav­el­ling are done by elec­tric mo­tors. As the LPS 420 E is a mem­ber of the LHM se­ries, it is also char­ac­terised by high mod­u­lar­ity. There­fore, it is a univer­sal all­rounder and a key as­set for han­dling every type of cargo, from con­tain­ers to bulk, gen­eral cargo and heavy lifts up to 124 t. The for­ward look­ing ma­chine is de­signed for ports and ter­mi­nals with an elec­tri­cal in­fra­struc­ture. Equipped with two winches, each with a pow­er­ful

190 kw elec­tric mo­tor, the LPS 420 E pro­vides a max­i­mum load ca­pac­ity of up to 124 tonnes.

Bulk Han­dling

With a turnover of up to 1,200 tonnes per hour, the new Lieb­herr LPS 420 E elec­tric crane ex­ceeds the av­er­age turnover of com­pa­ra­ble elec­tric driven cranes in the mar­ket. With a max­i­mum out­reach of up to 48 me­tres, ships with a size of up to Pana­max class can be served.

Con­tainer Han­dling

With up to 30 cy­cles per hour, the LPS 420 E is the per­fect so­lu­tion when it comes to con­tainer han­dling. Ship sizes up to post-pana­max class are ide­ally serv­able for the LPS 420 E. The op­er­a­tor of the new LPS 420 E can rely on very dy­namic elec­tric mo­tors. Fur­ther­more, the low mo­ment of in­er­tia en­sures a fast re­sponse of the mo­tor for pre­cise drive char­ac­ter­is­tics. Due to the high mo­tor speed spread no gear shift­ing be­tween nor­mal and heavy load is re­quired.

Lat­est Tech­nol­ogy

The LPS 420 E is es­pe­cially op­ti­mised for ter­mi­nals with a power sup­ply rang­ing from 380 V to 460 V. Thanks to the Lieb­herr ac­tive-front-end fre­quency con­verter de­vi­a­tions in the volt­age sup­ply can be com­pen­sated eas­ily for safe and sta­ble op­er­a­tion. Due to the crit­i­cal con­di­tions, like lim­ited space and harsh en­vi­ron­men­tal con­di­tions, a liq­uid-cooled and highly ef­fi­cient multi-drive fre­quency con­verter sys­tem was im­ple­mented. The com­pact unit en­sures a high power stor­age ca­pac­ity, which en­ables the ac­cu­mu­la­tion and sup­ply of 200 kw of power within 15 sec­onds.
