A 3000 kg twin rope synchronous winch built around a K-series hardened-tooth geared motor. Two grooved drums sit side by side on a common shaft, separated by a centre flange, and each rope spools in a single layer inside its own drum section \u2014 so both ropes pay out at the same rate from one drive. A mechanical height limiter with adjustable set positions stops the travel where you set it, and the electromagnetic brake can be released by hand for manual positioning. Rope speed 10 m\/min at a drum speed of 10.15 rpm, stroke 1 m, steel wire rope \u00d814 mm.<\/p>\n\n\n\n

Hardened gearing carries a higher tooth load in the same housing size than a soft-tooth unit, which is why a 7.5 kW frame can deliver 4562 N.m at the drum. The case reduction is 141.93:1, taking a 4-pole motor to a drum speed of 10.15 rpm.\nThe two grooved drums are machined side by side on one shaft with a centre flange between them. Because both drum sections turn as one body, the two ropes are driven from a single rotational reference \u2014 there is no second motor and no separate reducer that could fall out of step. The centre flange keeps the two ropes from migrating into each other's drum section.\nEach drum section is grooved so the rope lays into a defined groove instead of cross-winding. With a single layer, the effective winding radius stays constant through the whole travel, so the rope speed does not change as the rope builds up \u2014 the rope at the top of the stroke runs at the same speed as at the bottom.<\/code><\/pre>\n\n\n\nComplete Technical Specifications<\/h2>\n\n\n\nModelo: 3000 KG<\/td> Fuerza de tracci\u00f3n nominal: 3000 kg<\/td> Di\u00e1metro del cable de acero: 14 mm<\/td> Carrera: 1 m<\/td><\/tr> Potencia del motor: 7,5 kW<\/td> Velocidad del tambor: 10,15 rpm<\/td> Velocidad de la cuerda: 10 m\/min<\/td> <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nModelo: 3000 KG<\/td> A (Longitud): 998 mm<\/td> B(Ancho): 1184 mm<\/td> C(Altura): 685 mm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nSize Installation and System Interface<\/h2>\n\n\n\n1. The base frame has 68 mm slots rather than drilled holes, so the position can be adjusted along the slot when aligning to the structure. Use all four corner positions.\n2. Mount on a flat, rigid surface. The frame is a welded box; bolting it to an uneven surface twists the frame and misaligns the drum shaft.\n3. Design the supporting structure for the machine weight plus the 3000 kg rated pull. The machine weight is not stated in the source drawings \u2014 obtain it before finalising the structure.\n4. Allow clear space on the motor side for the 1184 mm projection and for brake access, because the manual release lever has to be reachable.\n5. Keep the rope lead within a few degrees of perpendicular to the drum axis. A side lead pulls the rope against the drum flange and the centre divider.\n6. The two rope exits are set by the drum geometry. Confirm your load's suspension spacing before mounting, because this spacing cannot be changed on site without changing the drums.<\/code><\/pre>\n\n\n\nControl Safety and Protection<\/h2>\n\n\n\n
The case machine is a direct-on-line or contactor-controlled unit: a 4-pole 7.5 kW motor through a 141.93:1 reducer gives a single rope speed of 10 m\/min. There is no variable-frequency drive in the case configuration, so the speed is fixed unless a VFD is added as an option.
The brake is electromagnetic and is released by the motor's own control circuit when the motor is energised. When power is removed, the brake applies. A manual release lever allows the brake to be opened by hand.<\/p>\n\n\n\n
Customization Options and Engineering Process<\/h2>\n\n\n\nConfigured around your operating conditions \u2014 Share the required lifting load, rope travel and diameter, operating speed, duty cycle, power supply, installation envelope and environment. KLD will review the application and provide a proposed configuration, technical drawing and quotation for approval.\nRequirements \u2192 Concept \u2192 Drawing & Quotation \u2192 Approval \u2192 Production & Test \u2192 Delivery<\/code><\/pre>\n\n\n\nStandards Testing and Quality<\/h2>\n\n\n\nThe company operates an ISO 9001 quality management system. CE conformity documents (LVD, EMC) are available for applicable configurations on request.\n\nFactory testing follows the approved technical specification for each configured unit and may include: no-load run, rated-load operation, twin-rope synchronization check, limit function and control verification. Available documentation may include dimensional drawings, electrical diagrams, inspection records and functional test results, depending on project scope.<\/code><\/pre>\n\n\n\nEngineering Cases<\/h2>\n\n\n\nApplication: a fixed lifting station needing two-point suspension of loads up to 3000 kg over a 1 m stroke, where the load has to stay level as it moves.\nConfiguration supplied: twin rope synchronous winch PJK-3000. K-series hardened-tooth geared motor, 7.5 kW 4-pole, reduction 141.93:1, drum speed 10.15 rpm, rope speed 10 m\/min. Two grooved drums \u00d8310 mm on a common shaft with a centre divider, single-layer spooling. Steel wire rope \u00d814 mm. Mechanical height limiter with adjustable set positions. Electromagnetic brake with manual release. Base frame 598 \u00d7 472 mm with 68 mm mounting slots; overall 998 \u00d7 1184 \u00d7 685 mm.\nWhy this configuration: a short, fixed stroke with two ropes meant the simplest synchronism solution was one shaft carrying both drums, rather than two drives with an electronic link. Single-layer spooling keeps the rope speed constant over the 1 m travel, so the two ends of the stroke behave the same. The adjustable mechanical limiter lets the same unit serve different fixtures by resetting the stops.<\/code><\/pre>\n\n\n\nTechnical Data Download<\/h2>\n\n\n\nDownloads:\n- Product Datasheet (PDF)\n- General Arrangement Drawing (PDF)\n- Installation & Operation Manual (PDF)\n- Request CAD \/ Electrical Drawing<\/code><\/pre>\n\n\n\nDelivery Packaging and Lifecycle Support<\/h2>\n\n\n\nMost winches are custom-made products; lead time is confirmed after technical approval and order review.
