The manual winch is a safety device governed by strict technical rules and whose design is framed by the European standard EN13157 A1.
Here are some criteria to be taken into account to select the right winch.
Quality winches designed in compliance with the European standard EN13157 A1, are provided for a maximum load capacity with a force on the handle that cannot exceed 25 kg first layer and last layer load).
This is a rated capacity and not a capacity of use. In general, one considers that a 12 kg force on the handle is acceptable. To obtain this maximum force level, the load on the winch should be limited to approximately 50% of its rated value.
The load capacity of the winch (100% force applied directly to the cable) depends on the cable winding level on the drum. In fact, the mechanical force transmited by the cable to the winch proportionally increases with the winding of the latter on the drum. In other words, the more the load is lifted, the more the transmitted force is significant, thereby reducing the capacity of the winch. For this reason, the standard considers a first layer and a last layer load:
The first layer is the minimum filling level of the drum. The load capacity of the winch given for a 25 kg force on the handle is then maximum, but is not a use value, as the winch cannot be used with this load (lifting/winding capacity equal to 0).
The maximum last layer load value, still for a 25 kg force on the handle, is the maximum capacity of the winch if the cable is completely wound on the drum.
Consequently, the winch capacity will depend on the cable length wound on the winch when the load is lifted to the maximum. To optimise this value and select the winch best suited for the application, it is necessary to limit the cable length wound on the drum to strictly: lifting height + 1 metre (minimum safety winding on the drum). Our Goliath Store configurator allows you to carry out simulations and indicates the references best suited for your application.
Each winch is determined according to a cable diameter adapted to its capacity. It is then recommended for optimum use of the winch to use the corresponding cable. A cable with a close diameter can eventually be used. WARNING! In this case, the winch capacity will eventually be reduced proportionally to the difference in breaking capacity of the cable.
WARNING-DANGER: Please note that ratchet winches are designed to be ideally used with a sling. In fact, as the drum diameter is often inferior to 30 mm, cables with a diameter superior to 4 mm have a radius of curvature which is too constrained and which breaks the steel fibre, causing the cable to break early.
WARNING-DANGER: The use of a sheave pulley with a diameter which is not appropriate for the cable also causes the cable to break early.
It is imperative that the winch be equipped with a protective cover preventing access to the mechanism in order to avoid any accident.
Since the 1980s, GOLIATH has gradually become the leading European manufacturer of manual winches. Our products, known for their quality, are distributed in all industries and integrated in numerous lifting products.
Our sustained investments in R&D for more than 10 years allowed us to launch new products every year. The Goliath range has thus become the most complete and competitive offer in terms of manual winch on the market, whether it concerns standard winches or lifting solutions dedicated to an application.
Our industrial flexibility, associated with a significant component library, allow us to offer, at low cost and within a limited time, lifting solutions suitable for the needs of integrators.
Our technical expertise in a great number of industries and applications allows us to easily adapt to OEM needs, with an industrial customisation approach.
Technical tailor-made solutions for industrial volumes (from 100 pieces a year, and for more significant systems up to several thousand units).
We provide integrators with customised solutions by adapting our winches (handle lengths, accessories, mounting system, additional handles, etc.) or by creating tailor-made products (reduction, size from our standard or modified component libraries according to specifications).
Our telescopic masts are available in standard or customised version up to 6 metres and 300 kg-load according to requirements. Our solutions also integrate accessories and mounting systems.
We also make hoist arm and davit systems in steel, aluminium, or stainless steel intended for handling various equipment.
Talbot Industrie provides overall lifting solutions intended to equip vehicles or industrial handling systems.
Talbot Industrie is also a manufacturer of trailers and offers tailor-made combined mobile lifting solutions, including lighting management solutions, material handling, building equipment and installation assistance. ....
Nos investissements soutenus en R&D depuis plus de 10 ans nous ont permis d’introduire chaque année de nouveaux produits. La gamme Goliath est ainsi devenue l’offre de treuil manuel la plus complète et la plus compétitive du marché, qu’il s’agisse de treuils standards ou de solutions de levage dédiée à une application.
Notre flexibilité industrielle, associée à une importante bibliothèque de composants, nous permet d’offrir, à moindre coût et dans un délai contraint, des solutions de levage adaptées aux besoins des intégrateurs.
Notre expertise technique dans de très nombreux secteurs d’activités et applications nous permet de nous adapter facilement aux besoins des OEM, dans une approche du sur-mesure industrielle.
Nous proposons aux intégrateurs des solutions sur-mesure en adaptant nos treuils (longueurs de manivelle, accessoires, système de fixation, poignées additionnelles …) ou en créant des produits sur-mesure (démultiplication, taille à partir de nos bibliothèques de composants standards ou modifiés suivant les cahiers des charges).
Nos mâts télescopiques sont disponibles en version standard ou sur-mesure jusque 6 mètres et 300 kg de charge suivant les besoins. Nos solutions intègrent également les accessoires et les systèmes de fixations.
Nous fabriquons également des systèmes de potences et davits en acier, aluminium, ou inox destinés à la manutention de divers équipements.
Talbot Industrie propose de réaliser des solutions globales de levage destinées à équiper des véhicules, ou des systèmes industriels de manutention.
Talbot Industrie est également fabricant de remorques et offre des solutions de levage mobile combinées sur mesure, qu’il s’agisse de solutions de gestion d’éclairage, de manutention, d’équipement pour le bâtiment, d’assistance à la pose en hauteur…
The norm EN13157 A1 defines the essential criteria to ensure your safety and allow us the put the CE stamp on our winches (in the case of use in the European Union)
Warning! The CE stamp can be based on a self-certification of the importer or the manufacturer, which sadly lead to an abusive usage and the non-compliance with the CE standards. Please be careful
A winch that is not in compliance with the EN13157 A1 is not CE, which renders the lifting product not in compliance with the directive on machinery safety for which you can be held liable.
You’ll find bellow a few of the compulsory criteria for the CE qualification of a winch. Of course, it shouldn’t be summarize just by these elements. Our goal is to allow you to visually identify some key elements to look out for:
With 40+ years of manufacturing innovation, we're ready to develop products to your exact specifications. Let's create the perfect solution for you.
