Brake Band ZP 01.242 for ZM-120U and ZMB-120U

Brake Band ZP 01.242 (for ZM-120U and ZMB-120U)

The ZP 01.242 brake band acts as the central friction part in the modernized band brake mechanism, which comes standard on high-performance new-generation grain loaders — the ZM-120U series machines from Zavod Moroza. The main engineering function of this element is to securely clamp the cylindrical drum of the pivoting frame (trimmer). Thanks to the tight wrap of the metal strip, the massive trimmer structure is firmly fixed in a set position, preventing its spontaneous displacement due to operational vibrations and the powerful recoil during grain discharge.

Structurally, the part is a flexible steel strip equipped with a mounting eyelet on one end and a special elongated rod on the other. The presence of this straight guide shank is a key design innovation of the modernized band, as the ZP 01.612 working spring is now placed directly onto it — this layout creates direct-action kinematics with exclusively linear tension transmission. The implementation of this system has made it possible to permanently get rid of unreliable intermediate rods and capricious washers, which in classic equipment models regularly misaligned and caused the trimmer lock to jam right during operation on the threshing floor.

Technical Specifications of Brake Band ZP 01.242

• Catalog number: ZP 01.242
• Application: ZM-120U, ZMB-120U
• Installation assembly: Trimmer band brake ZP 01.140
• Part type: Direct-action flexible friction band with an extended guide shank
• Quantity per unit: 1 pc.

The shape and dimensions of the updated ZP 01.242 band are specially adapted to operate within the direct-action kinematics of high-performance units. Structurally, the part has a mounting eyelet on one end (for a hinge connection with the flat drive lever), while its opposite end terminates in a long straight threaded rod. This integrated shank serves as the base for direct installation of the ZP 01.612 working spring — resulting in a perfectly straight, axial tension vector that completely eliminates any misalignments or angular shifts during the clamping or release of the pivoting frame drum.

The use of a band with an extended shank became a key step in abandoning unreliable intermediate links characteristic of classic machinery. In older locking mechanisms, a separate ZP 01.160 guide rod along with a specific ZP 01.608 spherical washer was required to transmit force. As operational practice showed, the accidental loss of this hinge washer or the bending of the rod itself led to severe metal scraping against the frame, destruction of mounting seats, and jamming of the entire assembly. The modernized ZP 01.242 part operates directly, making the mechanism much simpler structurally and completely fail-safe in practice.

The band itself is made of durable and flexible rolled metal that easily withstands intensive tensile and frictional loads. Thanks to the new linear transmission of force, the operator physically and very clearly feels the moment of complete mechanism unbraking. Such intuitive feedback serves as reliable engineering protection against the human factor — it prevents the operator from turning the massive trimmer while the brake is semi-clamped. This dramatically reduces the risk of premature wear on the metal strip, guaranteeing the machine ironclad locking of the discharge direction without parasitic backlash over many operating seasons.

Related Components of Brake Band ZP 01.242

In the kinematic scheme of the modernized direct-action band brake, the ZP 01.242 band functions not in isolation, but in tight mechanical connection with other control and power components. During maintenance or complete replacement of this friction strip on ZM-120U units, the following adjacent parts are subject to mandatory inspection:

• Brake handle ZP 01.150
• Brake lever ZP 01.000.2.2
• Working spring ZP 01.612
• Standard fixing elements (M12 adjusting nuts, lock washers, flat washers, and retaining cotter pins)

A similar principle of pivoting frame (trimmer) band locking is widely used not only on our new machines, but also on many other models of grain loading equipment. For high-performance units of our production, such as the ZM-120U and ZMB-120U, we always maintain the necessary stock of standardized ZP 01.242 bands in our warehouse. At the same time, we fully understand that farms operate many machines of various manufacturing years, units from other manufacturers, or machinery after individual retrofitting, where the dimensions or diameter of the brake drum may differ significantly. For such cases, our enterprise has all the necessary manufacturing capabilities to produce friction bands according to your individual parameters.

If your grain loader's locking mechanism has a non-standard configuration, our engineers are ready to quickly adapt the basic geometry of the band — we can change its overall length for a perfect drum wrap, use wider rolled metal to increase the contact area, and cut a different thread (or weld a specific bolt) on the guide shank. Upon separate request, to increase the friction coefficient and protect the metal drum from premature wear, we apply a special lining to the inner working surface of the band. We are ready to implement any design solutions to ensure ironclad reliability and stable operation of your machine's trimmer braking mechanism on the threshing floor.

Buy Brake Band ZP 01.242 for ZM-120U from Zavod Moroza

The manufacturing approach of Zavod Moroza is closely tied to the real practices of agricultural producers. Feedback from machine operators confirms that the brake band experiences the highest frictional wear when a massive trimmer is forced to turn while the brake is not fully released. Considering these extreme loads inherent in high-performance ZM-120U and ZMB-120U machines, we have completely moved away from unreliable kinematic schemes with intermediate rods. Our updated direct-action ZP 01.242 band is created from durable and flexible rolled metal and is equipped with an elongated guide rod. This ensures the maximum contact area with the drum and exceptional resistance of the part to tearing or deformation in the harsh conditions of the threshing floor.

By purchasing this friction part directly from our enterprise, you are completely insured against installation problems because you receive a product with strictly verified geometric parameters that flawlessly integrates into the locking mechanism and restores its correct linear action. Our own production facilities allow us to seamlessly ship standardized bands from stock and promptly execute individual orders — adapting basic length, strip width, or applying additional wear-resistant lining tailored to the specific needs or non-standard drums of your farm.
