Il est constitué d'un capteur de poids (3) et d'un support (4) qui sont intercalés entre le bras de levage (1) et le moyen de préhension (2) et qui sont placés à l'intérieur de l'extrémité dudit bras de levage (1).  It consists of a weight sensor (3) and a support (4) which are interposed between the lifting arm (1) and the gripping means (2) and which are placed inside the end of said lifting arm (1).

Le support (4) du capteur de poids (3) possède un profil extérieur dont la forme et les dimensions sont adaptées pour permettre son emboîtement dans le profil intérieur du bras de levage (1).  The support (4) of the weight sensor (3) has an outer profile whose shape and dimensions are adapted to allow it to fit into the inner profile of the lifting arm (1).

L'ensemble de pesage comporte également un indicateur de poids (5) qui est fixé au support (4) du capteur de poids (3) à l'extérieur de l'extrémité du bras de levage (1). La liaison entre l'extrémité du capteur de poids (3) et le moyen (2) de préhension de la charge, est assurée au moyen d'une pièce (6) qui traverse la partie inférieure du bras de levage (1).  The weighing assembly also includes a weight indicator (5) which is attached to the weight sensor support (4) (3) outside the end of the lift arm (1). The connection between the end of the weight sensor (3) and the means (2) for gripping the load is ensured by means of a part (6) which passes through the lower part of the lifting arm (1).

La mise en place de la pièce de liaison (6) peut utiliser les ouvertures (1A) et (1B) du bras (1) prévues pour positionner et fixer initialement le moyen (2) de préhension de la charge à soulever.  The establishment of the connecting piece (6) can use the openings (1A) and (1B) of the arm (1) provided for positioning and initially fix the means (2) for gripping the load to be lifted.

La pièce de liaison (6) comporte un dispositif, du type cardan (6A), câble (6B) ou rondelles sphériques (6C), permettant de désaccoupler l'effort (F) de la charge.  The connecting piece (6) comprises a device, of the cardan type (6A), cable (6B) or spherical washers (6C), for uncoupling the force (F) of the load.

Elle est maintenue au capteur de poids (3) au moyen d'un ensemble écrou et rondelle (6D).  It is held at the weight sensor (3) by means of a nut and washer assembly (6D).

L'indicateur de poids (5) comporte un emplacement (5A) destiné à contenir une source 30 d'énergie autonome, un afficheur (5B) et des boutons de commande (5C).
