Trimmer Brake Lever ZP 01.000.2.2 for ZM-60U/90U/120U

Trimmer Brake Lever ZP 01.000.2.2 for ZM-60U/90U/120U + ZMB

The ZP 01.000.2.2 brake lever is an actuating power element of the modernized band brake system standard on our new generation machines: the ZM-60U, ZM-90U, and ZM-120U. In the overall kinematic layout of the locking assembly, this part functions as the primary mechanical lever, converting the control force into a rigid linear tension of the friction brake band.

The main engineering task of the part is to ensure quick and reliable blocking of the pivoting mechanism. Thanks to the correctly calculated geometry and force application arm, the lever allows operators to create sufficient working pressure with minimal physical effort so that the metal band tightly compresses the drum. This guarantees stable retention of the set position without parasitic backlashes, completely eliminating spontaneous displacement or turning of the massive trimmer structure under the influence of the unit's operational vibrations on the threshing floor.

As seen from the kinematic layout, the ZP 01.000.2.2 lever is a rigid flat metal plate with a curved (crescent) profile. The part is equipped with mounting holes and a pin, through which it movably connects the eccentric of the ZP 01.150 brake control handle to the eyelet of the brake band. The profile and arm length of the lever are calculated to optimally convert the rotational movement of the handle into a direct linear tension of the metal band around the trimmer drum.

The introduction of this lever into the kinematics of the modern band brake made it possible to eliminate a complex system of intermediate parts. In classic grain loaders, the force on the band was transmitted via a long ZP 01.160 guide rod that passed through a through-hole in the frame. Since the angle of inclination of the rod constantly changed during the movement of the control lever, a specific spherical (ball-and-socket) washer ZP 01.608 was necessarily used to prevent it from jamming. Operational practice showed that the loss of this small washer during field repairs or the slightest bend in the rod itself led to severe metal friction against the edges of the frame hole. The mechanism began to jam, and releasing the trimmer required excessive physical effort from the operator.

In the modernized assembly, the ZP 01.000.2.2 lever operates exclusively in a single plane, reducing the kinematics to simple linear force transmission. Long rods that easily deformed under load and small spherical washers that frequently got lost on the threshing floor are excluded from the design. Thanks to the new shape of the lever, force transmission from the handle to the band occurs without parasitic angular misalignments, eliminating the risk of binding. The mechanism has become more rigid, structurally reliable, and maintains ease of movement regardless of operating conditions and unit vibrations.

Since the ZP 01.000.2.2 lever acts as the central power and connecting link in direct-action kinematics, during its maintenance or comprehensive retrofitting of the locking mechanism, the following adjacent components must be checked and installed:

• Brake handle ZP 01.150
• Brake band ZP 01.241 (for ZM-60U/90U) or ZP 01.242 (for ZM-120U)
• Spring ZP 01.612
• Fixing elements: support washers and cotter pins

In classic locking mechanisms with rods and spherical washers, the frequent cause of breakdowns was precisely the human factor. Due to the general capriciousness of the assembly and its tendency to jam, operators often had to apply excessive force trying to turn the trimmer, which led to part deformation. The introduction of the ZP 01.000.2.2 lever radically changed this process — the part features a reinforced metal profile that easily withstands maximum loads without the risk of bending, and its operation principle has become much more convenient and intuitive for personnel.

Thanks to the direct action of this lever, force from the control handle is transmitted to the band clearly and linearly. The operator physically feels the moment of complete unbraking and rigid locking, which naturally minimizes human error — the system has become practically impossible to "over-tighten" or damage due to misunderstanding the actuation moment. Numerous reviews from engineers and operators on farms that have been operating our modernized units for many years confirm that the updated mechanism with this lever works excellently, smoothly, and flawlessly even under the most difficult threshing floor conditions.

Transitioning to the reinforced ZP 01.000.2.2 lever combined with the updated band and handle is a reliable way to permanently get rid of chronic trimmer jamming problems. You get simple, durable, and intuitive kinematics that minimize the human factor and guarantee uninterrupted functioning of the locking assembly for many operational seasons.
