Band Brake Assembly ZP 01.140 for ZM-60U/90U/120U

Band Brake Assembly ZP 01.140 (for Trimmer ZM-60U/90U/120U)

The modernized ZP 01.140 band brake is the main friction locking assembly for the pivoting frame (trimmer) standard on the upgraded ZM-60U, ZM-90U, and ZM-120U series grain loaders of our production. Its primary engineering task is to securely lock the massive trimmer in a set operating position, preventing its spontaneous turning under operational vibrations or the recoil from an intensive grain flow.

Structurally, this mechanism operates on the principle of a normally closed direct-action system. The assembly consists of three main elements: the ZP 01.150 brake control handle, the brake band with an extended guide shank (ZP 01.241 for ZM-60U/90U or ZM-120U for ZM-120U), and the powerful ZP 01.612 working spring. The spring is mounted directly onto the straight rod of the band itself, creating a constant linear tension that forces the metal strip to tightly wrap around the cylindrical drum of the pivoting frame.

To change the grain discharge direction, the operator moves the handle, overcoming the spring's resistance — the handle's eccentric linearly pushes the band forward toward the drum, creating the necessary slack to turn the trimmer manually. After setting the desired angle, the handle returns to its initial position, and the spring tightly clamps the drum once again.

Analyzing the long-term operational practice of classic grain loaders, Zavod Moroza designers identified a chronic vulnerability in the old trimmer locking mechanism. In the classic layout, force from the lever was transmitted to the band via a complex intermediate system: the ZP 01.160 guide rod passing through a hole in the frame, and the specific ZP 01.608 spherical hinge washer. Because the lever moved along an arc, the rod constantly changed its angle of inclination. The loss of the spherical washer during repairs on the threshing floor or the slightest misalignment caused the rod to scrape hard against the edges of the hole, quickly bending it, deforming the holes, and jamming the entire assembly.

For the new generation of machines, we significantly revised this kinematics, applying a direct-action engineering principle. In the modernized brake, we completely abandoned the use of the intermediate rod and capricious spherical hinges. Instead, the design of the band itself was modified: it received an extended straight shank onto which the ZP 01.612 working spring is mounted directly. The updated control handle (ZP 01.150) also features a different eccentric geometry — now, when shifting the handle, force is transmitted perfectly linearly, pushing the band toward the drum without any angular deviations or misalignments.

This engineering optimization made it possible to eliminate all weak and problematic links from the design. Thanks to the transition to direct linear action, the modernized trimmer locking assembly has become structurally much simpler, features a smoother handle travel, and is completely fail-safe, guaranteeing secure retention of the pivoting frame even under maximum vibrations and grain flow recoil.

Components of Band Brake ZP 01.140

For complete maintenance or a major overhaul of the trimmer locking unit, the modernized assembly includes the following parts:

• Brake handle ZP 01.150
• Brake band ZP 01.241 for ZM-60U/90U or ZM-120U for ZM-120U
• Spring ZP 01.612
• Fastening elements (adjusting nuts, cotter pins, washers)

Grain loader maintenance practice shows that the trimmer locking mechanism most often suffers not from natural metal wear, but precisely due to the human factor and violations of operating rules. The most typical mistake on the threshing floor is an operator attempting to turn the massive trimmer frame by force without bringing the unbraking handle to the extreme open position (to the lock). In such cases, the mechanism remains semi-clamped, and during rotation, the drum acts like sandpaper — this thins the brake band and stretches its metal. Moreover, in older systems, if the assembly was unlubricated and operated stiffly, operators often applied excessive force, leading to irreversible bending of the control handle or misalignment and loss of spring rigidity.

Understanding these harsh operating realities, we engineered maximum personnel error protection into the design of the modernized ZP 01.140 band brake. Abandoning capricious intermediate rods in favor of direct action means that the powerful ZP 01.612 working spring always compresses strictly linearly along the extended band shank, without bowing into an arc even during sharp or careless jerks. The updated ZP 01.150 brake handle received a more rigid base and correct eccentric geometry. Now it has an easy and intuitive travel, which naturally prompts the operator to fully unbrake the assembly before turning, protecting the band itself from burning and premature rupture.

Choosing the modernized ZP 01.140 assembly and its components manufactured by Zavod Moroza gives you an engineering-perfect system capable of forgiving operational carelessness. Our parts are designed to minimize the impact of the human factor on wear. Installing this kit radically simplifies machine control and guarantees absolutely fail-safe operation of the trimmer lock, permanently sparing your farm from regular replacements of bent handles or deformed springs during intensive work.
