WINCH RE­VIEW

NZ4WD - - CONTENTS -

Iron­man 4x4 has to­tally re­designed and up­graded its range of mon­ster winches, in­clud­ing stronger mo­tors, heavy duty cas­ings, syn­thetic ropes, com­pe­ti­tion style so­le­noids – and they are the only winches on the mar­ket with a mo­tor breather. With two in the range, a 9,500lb and a 12,000lb, and with the op­tion of steel or syn­thetic cable, the com­pany of­fers a winch to suit your needs.

En­gine breather

The great­est new fea­ture of the Mon­ster range is the fully sealed mo­tor, with a breather that al­lows the mo­tor to equalise changes in tem­per­a­ture and pres­sure by means of a re­mote breather hose which can be placed high in the ve­hi­cle away from wa­ter. The Iron­man Mon­ster winch is the only winch on the mar­ket with this fea­ture. Is­sues tend to arise when winches come into con­tact with wa­ter or when they heat and cool, draw­ing in mois­ture which re­sults in cor­ro­sion, es­pe­cially when they are not used or ser­viced reg­u­larly. The sealed mo­tor keeps the mo­tor dry while the re­mote breather al­lows it to breathe to out­side away from wa­ter. The 12,000lb mon­ster winch has a 6hp (4.5kw) se­ries wound mo­tor while the 9,500lb uses a 5.5hp (4.1kw) se­ries wound mo­tor. Both have sealed wa­ter­proof bear­ings at both ends of the ar­ma­ture for bet­ter sta­bil­ity and re­duced fric­tion. The ar­ma­tures are in­di­vid­u­ally bal­anced for high speed op­er­a­tion, all wiring is coated for heat pro­tec­tion and Iron­man have added an ex­ter­nal heat sink with in­creased sur­face area to trans­mit heat away from the mo­tor.

Gear­box

The winch gear­box uses pre­ci­sion machined hard­ened gears while the clutch mech­a­nism uses a slid­ing sys­tem with straight cut gears and the han­dle has been notched to en­sure it re­mains in the se­lected po­si­tion. The ro­tat­able gear­box al­lows po­si­tion­ing of the clutch han­dle to al­low fit­ment to most bars and easy hand ac­cess, and the re­de­vel­op­ment has re­sulted in a low pro­file clutch han­dle al­low­ing for a more uni­ver­sal fit. Gear­boxes are com­pletely sealed and use pre­mium high qual­ity lithium grease to re­duce the ef­fect of heat, wa­ter and ox­i­diza­tion.

Con­trol box

The Iron­man con­trol box is wa­ter­proofed and sealed to re­sist wa­ter con­tam­i­na­tion, re­duc­ing the risk of short­ing out. The so­le­noid used is com­pletely sealed, and has tung­sten tipped con­tacts pro­vid­ing long life and re­sis­tance to arc­ing.

Drums and cable

Drums are fit­ted with an au­to­matic Cam Loc which holds the drum in po­si­tion when winch­ing stops. This cam lock sys­tem pro­duces very lit­tle heat and ac­ti­vates quickly. Winches can either be spec­i­fied with 28m of 8.3mm ( 9,500lb) or 9.4mm (12,000lb) of wire cable or 28m of syn­thetic rope.

Gen­eral

All winches come with full wiring kits and in­struc­tions, four-way roller fair­lead or al­loy hawse fair­lead, winch damper blan­ket and a fiveyear war­ranty. Spare parts are car­ried in NZ and are read­ily avail­able should they be re­quired. Iron­man Mon­ster winches have a stan­dard bolt mount­ing pat­tern which will al­low them to fit to most bars and ve­hi­cles. Prices start from $ 1,249.
