Traction depends on rope condition, number of drum windings and friction coefficient. It is not a powered winch, cannot be used with VFD\/encoder\/remote-control options, and is not intended for personnel lifting.<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Features Benefits<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Friction drive \u2014 the rope is wound several turns around one driving drum and one driven drum, and friction generated by the windings acts as the driving force for rail-free movement in a defined area.<br>Simple and direct \u2014 the crank is linked directly to the drum with no gearbox; turning the crank moves the rope back and forth to deliver materials uphill quickly.<br>Fast braking \u2014 torsion-spring bidirectional mechanical braking allows quick stops, which helps improve safety during transport and reduce accidental incidents.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Complete Technical Specifications<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Fuerza m\u00e1xima de tracci\u00f3n de los cabrestantes: 25 kg<\/td><td>Di\u00e1metro de la cuerda: 8 mm<\/td><td>Peso propio: 13,5 kg<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Fuerza m\u00e1xima de tracci\u00f3n de los cabrestantes: 25 kg<\/td><td>A (Longitud) 280 mm<\/td><td>B (Ancho) 134 mm<\/td><td>C (Altura) 196 mm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Size Installation and System Interface<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Outline dimensions (case): 280 \u00d7 134 \u00d7 196 mm (L \u00d7 W \u00d7 H).<br>Mounting: enclosed body with mounting holes on the housing; the unit is carried or fixed depending on the site.<br>Rope interface: wire rope \u00d88 mm wound around both drums, then fixed to the trolley or load.<br>Working posture: hand crank on the shaft; braking via torsion-spring bidirectional mechanical brake.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Control Safety and Protection<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>- Torsion-spring bidirectional mechanical brake for quick stopping in both directions.\n- Enclosed protective guard helps protect internal parts in dusty or no-power environments.\n- Manual 1:1 crank drive \u2014 no electrical component, so no electrical hazard.\n- Drum winding friction acts as the driving resistance; the rope should be checked for wear and correct winding before each use.\n- Not intended for personnel lifting.<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Customization Options and Engineering Process<\/h2>\n\n\n\n<pre class=\"wp-block-code\"><code>Configured around your operating conditions \u2014 Share the required line pull, rope travel, operating speed, duty cycle, power supply, installation envelope and environment.
