Quadro chain hoist for a broad range of ap­pli­ca­tions

DEMM Engineering & Manufacturing - - PRODUCT WATCH - WWW.TRIMATE.NET

FIT­TED WITH four load hooks, the Demag LDC- Q quadro chain hoist al­lows dif­fer­ent load han­dling at­tach­ments to be lif ted and trans­ported at the same time. The avail­able LDC- Q sizes en­able loads weigh­ing up to 3.2 tonnes to be han­dled safely and ef­fi­ciently.

The Demag LDC- Q quadro chain hoist can be used for a wide va­ri­ety of han­dling re­quire­ments in pro­duc­tion and lo­gis­tics ap­pli­ca­tions. Equipped with four load hooks, LDC- Q units can han­dle and trans­port cus­tomer- spe­cific load han­dling at­tach­ments or flat com­po­nents and feed ma­te­ri­als to the rel­e­vant work­sta­tions.

The ba­sis for this broad range of ap­pli­ca­tions is the tech­nol­ogy of­fered by the LDC-D dou­ble chain hoist and some ded­i­cated char­ac­ter­is­tics. For ex­am­ple, these in­clude a de­sign that com­bines two dou­ble chain hoists which have only one drive, which is a spe­cial tech­ni­cal fea­ture. This means that only one chain hoist mo­tor trans­fers power to the other three chain lead- offs of the Demag LDC- Q quadro unit via cor­re­spond­ing con­nec­tions. Me­chan­i­cally syn­chro­nised hook lead- offs pro­vide for uni­form and pre­cise load han­dling. This ar­range­ment en­ables loads with an asym­met­ri­cal weight dis­tri­bu­tion up to a ra­tio of 70:30 to be picked up with­out any prob­lems.

ProHub in­te­grated vari­able speed con­trol, which is a fea­ture unique to Demag chain hoists, also per­mits rated speeds of up to 90 per­cent higher in the par­tial load range. Op­er­a­tors can utilise sizes DC 10 and DC 25 for han­dling loads weigh­ing up to 3.2 tonnes. The Demag LDC- Q quadro chain hoist of­fers ben­e­fits for safe and ef­fi­cient lif ting. Oper­a­tion of the con­trol unit with low volt­age (24 V con­tac­tor con­trol) as well as smooth start­ing and brak­ing for low load sway are also sig­nif­i­cant fac­tors. Fur­ther safety- re­lated func­tions sat­isfy at least Per­for­mance Level c and Cat­e­gory 2 to EN ISO 13849-1.

Be­sides safety, ser­vice is also of ma­jor im­por­tance. The ‘gen­er­ously di­men­sioned’ slip­ping clutch and gear­box, which is main­te­nance-free for up to 10 years, as well as fast and sim­ple main­te­nance of in­di­vid­ual com­po­nents thanks to its mod­u­lar de­sign, help to make the Demag LDC- Q quadro chain hoist easy to ser­vice, prom­ises the man­u­fac­turer. These are all im­por­tant as­pects that min­imise down­times and ex­tend the unit’s ser­vice life for im­proved pro­duc­tiv­ity.

For con­trol of the Demag LDC- Q quadro chain hoist, op­er­a­tors also ben­e­fit from DSC/DSE con­trol pen­dants with their low-fa­tigue ac­tu­a­tion force for im­proved er­gonomics. To meet spe­cific er­gonomics needs, op­er­a­tors can choose be­tween ra­dio con­trols or ca­ble- con­nected con­trol pen­dants that can be in­te­grated into sta­tion­ary con­trol units.

And ul­ti­mately, states Demag, 2D and 3D ge­om­e­try mod­els in the Demag De­signer tool give own­ers the op­por­tu­nity to view a po­ten­tial so­lu­tion and its pre­cise ar­range­ment in their ex­ist­ing build­ing and ma­chin­ery in­fra­struc­ture al­ready at the pre- plan­ning stage.
