Their principal features and most significant advantages are • compact dimensions • ease of maintenance • long operation life • high performance • modular design of gear unit • functional design With these characteristics the machine designer will get a ready to install unit and will achieve economic solutions even in confined space conditions. Potential applications: • mobile cranes • construction cranes and conveyors • material and working elevators • loading and cargo handling cranes • shipboard and deck cranes • rescue and wrecker salvage trucks • dockyard and harbour cranes • offshore cranes • container gantries • access platforms ZOLLERN gears use components common to our complete range (Winches, Slewing Units, Industrial Gears, Free Fall Winches) giving the advantage of volume production: cost savings from standard parts, reduced lead times, tested and proven designs across the whole range and readily available spares for units in service. DESIGN AND CONSTRUCTION OF ROPE WINCHES WITH FLANGE DRIVE GEARBOX 2 stage planetary gearbox Ratios from i = 21 to 29 Gearbox mounted inside winch drum, Parking Brake and Hydraulic motor flange mounted externally. Input and output in opposite sense of rotation. 3 stage planetary gearbox Ratios from i = 45 to 147 Gearbox mounted inside winch drum, Parking Brake and Hydraulic motor flange mounted externally. Input and output in opposite sense of rotation. 2 stage planetary gearbox with spur stage input Ratios from i = 40 to 150 Gearbox mounted inside winch drum, Parking Brake and Hydraulic motor flange mounted externally, twin motor/brake option. Input and output in opposite sense of rotation. WINCH GEARBOXES Winch Gearbox Range Output torques: 1,750 to 1,500,000 Nm. Rope load: 17 to 1,950 kN. In calculating the rope load care must be taken to include reeving, hooks and an allowance for reeving efficiency (see page 11). Lubrication All gears and anti-friction bearings are splash lubricated. Service intervals and recommended lubricants are given in the table on page 16. The end support bearing can be grease packed for lifetime operation – requiring no further service attention. Oil change An external fill/breather/drain pipe is fitted to the drive flange of winch gearbox. Oil level Oil level is checked by either dip stick or sight glass. Notes The output torques Tdyn max, listed on pages 12/13 are based on FEM Standards I/3rd edition/load conditions L2 running time classification T5, in accordance with ‘Drive unit group M5’. Ambient temperature +20 C° (FEM - Federation Europeenne de la Manutention). 4 5 Gear Design Selected for optimum surface durability and bending strength; also for minimum sliding velocity, according DIN 3990. External gear teeth are case-hardened and ground; internal gears annealed and nitride hardened. Cooling Cooling may be required where the unit is to operate continuously in direct sunlight or high ambient temperature environments. Cooling may be also required if the power on time is high. ZOLLERN can provide suitable coolers. Bearings All rotation parts run on rotation element bearings. Ball bearings are used to support the input gearing, needle roller bearings for the planet wheels and self aligning bearings for the drum support bearings. Input Options ZOLLERN’s modular system provides for hydraulic or electric motor input interfaces. Flange mounted or free shaftwith key to DIN 5480. Seals Efficiency The efficiency per planetary stage is 98% and about 99% for the drum bearings including seals. Example: Rope winch with 2 planetary gear stages η total = 0,98 x 0,98 x 0,99 = 0,95 Input and output are protected with radial shaft seals of double lip type. This prevents oil leakage and protects the unit from ingress of dirt or water. Where the unit is be used offshore or on-ship additional protection is provided with greased felt strips and secondary radial seals. Mounting position Horizontal Brakes A hydraulic multi disc parking brake with spring applied, pressure release operation is fitted. This fail safe device is a self contained piston/ brake with release pressure of 15 bar, 300 bar max. Line transient pressure of 0.5 bar permitted. The connection ports are metric M 12 x 1.5. Multi disc, single disc or barrel brakes with direct connection to the rope drum can be fitted for additional safety back up. Fitting ZOLLERN’s winch gearbox is designed to be flange mounted in a fabricated steel structure. The drive end mounting flange reacts rope load and transmission torque, the non drive end reacts rope loads only and can be safely removes to facilitate fitting of the winch drum and gearbox. Backstop For special applications a backstop can be incorporated between the gear transmission and the parking brake. It operates as follows. Lifting of load - Parking brake closed - Backstop open Lowering of load - Parking brake open - Backstop closed Electric motor Standard electric motors cannot be mounted inside the winch drum. As opposed to Electric-Compact-Winch. Operating conditions The gear systems are designed for use in Central European conditions. Permissible oil temperatures -20°C to +70°C. Environmental factors such as salt water, salt-laden air, dust, excessive air pressure, heavy vibration, high shock loads and extreme ambient temperatures, corrosive media, etc. must be stated. Geared limit switch a) electrical an electrical signal can be generated at various rope travel or end limit position. The switch positions are infinitely adjustable. The switch is flange mounted with drive from the rope drum through the bearing support housing. b) hydraulic ZOLLERN geared limit switch operating as the electrical version – with a hydraulic signal. Paint Primer This is a specially developed multi-primer with a twocomponent zinc-dust epoxy resin base. Colour: Grey white. A two component epoxy resin is most suitable for the finish coat. Choice of gear unit In order to select the correct rope winch for a given application the output torque Tdyn calculated from the rope load and rope drum diameter must be multiplied by the factor K. Tnom = Tdyn x K ≤ Tdyn max For application factor K and calculation of the rope load see pages 10. WINCH GEARBOXES INTEGRATED ROPE DRUM 6 7 With normal grooves With special grooves Raising wedge This is cast on to the drum on the opposite side of the rope entry and guides the rope from the first to the second layer. Dummy-lay filling wedge With grooves of this kind the difficulties encountered in multi-layer winding on to grooves of the usual kind do not arise, as the crossover points of the rope in each layer always lie in the same section of the drum and the lift of the rope into the next layer is precisely defined. 8 and more layers can be accommodated without difficulty. This is cast on to the drum at the rope entry point and serves to fill the gap between the drum flange and the first rope turn. Material for rope drum: - ductile graphite iron (EN-GJS-400-15; EN-GJS-600-3) - steel (S355JO) Other material available on request Rope drum diameter D1 1,5 . d Drum flange diameter D2 D2 = D1 + 2 (z + 1) d D1 = 20 x d or as specified d Length of rope including 3 safety turns LS = LS L2 D1 d D2 ( )( L2 -a p D1 D1 + 0,866 . d (z-1) ) z.π 1000 p z a = Pitch of rope groove [mm] = Number of rope layers [–] = 1 for normal grooves [–] = 0,5 for special grooves = Length of rope [m] = Length of drum [mm] = Diameter of drum [mm] = Diameter of rope [mm] ROPE FIXING Wedge lock a) on the outside of the drum flange Rope Clamps a) on the outside of the drum flange b) on the inside of the drum flange (for up to 2 rope layers only) b) on the inside of the drum flange (for up to 2 rope layers) c) within the barrel shell c) on the drum by means of clamps. In an emergency the rope can be pulled out of the fixing without damage to either rope or drum. WINCH GEARBOXES 8 9 ROPE GROOVES AND ROPE Rope grooves On cast drums cleanly cast and trimmed, and at the flash line carefully ground. On welded drums all edges are deburred and radiussed. α Fleet angle To achieve acceptable rope winding - the deflection angle α must with special grooves be not less than 0,5° in order to prevent the rope from riding up the drum flange and to ensure that it is guided securely on to the next layer. - the deflection angle α must not exceed 1,5° in order to prevent the rope in the first layer being pulled against the grooves and, where a number of layers occur, to enable even winding up to the drum flanges. If the deflection angle is greater, the working life of the rope will be negatively affected. Rope groove lead/pitch Right-hand lead on standard design Left hand lead Direction of rope lay Rope lay should be in the opposite sense to drum lead. For example: right-hand rope lay left-hand rope lay APPLICATION FACTOR K FOR WINCHES Symbol Running time classification Mean running time per day in hours, related to one year Life in hours 8 years, 200 days/year Load conditions L1 L2 L3 L4 M log M log M log M log L L L L T2 over 0,25 to 0,5 400 to 800 T3 over 0,5 to 1 800 to 1 600 T4 over 1 to 2 1 600 to 3 200 T5 over 2 to 4 3 200 to 6 300 T6 over 4 to 8 6 300 to 12 500 T7 over 8 to 16 12 500 to 25 000 T8 over 16 25 000 to 50 000 Collective coefficient km to 0,125 0,125 to 0,250 0,250 to 0,500 0,500 to 1,000 M1 0,90 M2 0,90 M3 1,05 M4 1,32 M2 0,90 M3 0,92 M4 1,09 M5 1,36 M3 0,92 M4 0,96 M5 1,17 M6 1,46 Drive unit class Application Factor K M4 0,9 M5 1 M6 1,23 M7 1,53 M5 0,92 M6 1,07 M7 1,28 M8 1,58 M6 1,1 M7 1,3 M8 1,53 M8 1,8 M7 1,36 M8 1,6 M8 1,89 M8 2,22 CLASSIFICATION GUIDANCE According FEM section I, 3rd edition, table T.2.1.3.5.

A single pulley block is the total number of rope strands and rope pulleys for a single rope running on to a rope drum (see illustration) ηR is the efficiency of a single rope pulley ηF is the efficiency of the pulley block ηs is the efficiency of the rope drive The efficiency of a rope pulley depends not only from its type of bearing used in it (friction or antifriction), but also upon the ratio rope pulley diameter: rope diameter (D:d), upon the design of the rope and upon the rope lubrication. If no more exact values have been obtained by experiment, the following values are to apply with friction bearings ηR = 0,96 with anti-friction bearings ηR = 0,98 For compensating pulleys no efficiency value must be considered.
