The invention relates to a tension ratchet with a belt magazine, for rapidly fixing a good to be transported to a vehicle, an object to a support, or several objects to each other. The tension ratchet (30) is combined with a belt magazine (1) which receives the entire idle belt supply during use and during storage and ensures rapid tying down/releasing of e.g. a transport load, due to constant availability for use; as well as tidy storage. The belt magazine (1) is arranged in such a way that it lies flat on the lower arm of the tension ratchet (30) in order to reduce the construction height, with a vertical belt winding up shaft (15) for receiving a belt to be wound up in horizontal rotation. The belt runs into the tension ratchet out of the belt magazine on its back side in the winding position, rotates about 90° in said tension ratchet and is then led out through the load tensioning roller (8).
A tensioning ratchet (30) with belt magazine (1) for winding up a non-active stock of a tensioning belt (19), in which the tensioning ratchet (30) contains a load tensioning roller (8) and an actuator for the latter, and the belt magazine (1) has a belt winding device (14, 15), characterized in that the belt winding device (14, 15) has a winding axis that runs essentially perpendicular to the axial direction of the load tensioning roller (8).

The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the belt guides (17, 17a) have rotatably mounted sleeves, sliding rollers or the like.
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the belt (19, 24) is rotated by 90° between the belt guides (17, 17a) and the load-tensioning roller (8).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the stopper (4) is situated at a radial angle to the load tensioning roller (8), which corresponds to or exceeds the angle of the rotated belt progression between the load tensioning roller (8) and the belt guides (17, 17a).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the stopper (4) is spring-loaded on its lower side facing the floor part (2) in the direction toward the locking wheel (9, 9a).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the stoppers (4, 11) engage the locking wheels (9, 9a) in a radial and shape-conforming manner.
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that a second belt (27) is secured to the traverse (25), and the other end of the belt has a connection means, e.g., a hook.
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that an attachment part (28) with a locking mechanism (26) is secured to the traverse (25) for attaching a second belt (27).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized by a strap (7) pivoted in the lateral walls (3, 3a) for attaching a second belt (27).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the strap (7) is essentially U-shaped, and has bends (7a, 7b).
The tensioning ratchet with belt magazine according to one or more of the preceding claims, characterized in that the strap (7) has securing means (29, 29a) at its two ends extending through the lateral walls (3, 3a) into the inside of the lower arm to prevent sliding out.
