Front Travel Brake Band ZP 01.000.1.3

Front Travel Brake Band ZP 01.000.1.3

The ZP 01.000.1.3 front travel brake band is the direct working (friction) element of the modernized direction-of-travel locking system equipped on modern ZM-60U, ZM-90U, ZM-120U series grain loaders and their ZMB hopper modifications. In the steering kinematics scheme, this part functions as a flexible clamp responsible for rigidly holding the unit's pivoting strut on a set course.

Structurally, the part is a curved metal strip mounted on the machine's main frame that geometrically encompasses a steel drum (rim) welded to the large driven steering sprocket. The ends of the band connect to a support pin on the frame and a control screw handle. When the operator turns the handle to lock the direction, the mechanism draws the ends of the band together, causing it to tightly compress the sprocket drum. The friction force generated by this contact reliably locks the steering assembly in the set position, preventing spontaneous turning of the front wheels caused by vibrations from operating mechanisms or when moving over uneven threshing floor surfaces.

Technical Specifications of Front Travel Brake Band ZP 01.000.1.3

• Catalog number: ZP 01.000.1.3
• Application: Modernized grain loaders ZM-60U, ZM-90U, ZM-120U and their ZMB hopper modifications
• Purpose: Friction stepless fixation (blocking) of the front travel direction
• Construction: Flexible metal strip with eyelets for connection to the tension mechanism
• Contact adjacent assemblies: Steering sprocket ZP 01.402 with a welded steel rim

Structurally, the brake band acts as the main friction element of the mechanism, tightening around the steel drum of the large driven steering sprocket. Driven by the motion created by the rotation of the screw handle, the ends of the band converge, ensuring its uniform and tight compression against the working surface. This kinematics allows the band itself to rigidly hold the wheel base in the set position, enabling the operator to meter the clamping force without the risk of losing friction contact under the unit's operational vibrations.

The use of this band-based locking principle eliminated the engineering vulnerabilities characteristic of classic grain loaders, where course locking was performed by a metal stopper between the teeth of the small sprocket shaft. Unlike the archaic lock that limited adjustment accuracy with the rigid pitch of a gear transmission, the smooth inner plane of the band guarantees smooth, stepless steering fixation at absolutely any angle. This also eliminates ergonomic issues: the operator no longer needs to additionally spin the heavy steering wheel while "catching" the clearance, as used to happen when a gear stopper rested against a tooth face. Furthermore, because the band encompasses the large sprocket, the braking point is shifted to a significantly larger radius of the drum - here, the contact area of the band effectively disperses physical stresses, reliably protecting the steering drive from extreme concentrated impacts from the wheels, shearing of locking elements, and the development of parasitic backlashes.

Related Parts of the Band Brake Mechanism

Since the ZP 01.000.1.3 brake band is purely an actuating friction element, its operation relies on a tight connection with other components of the modernized course-locking assembly. The basic list of adjacent parts includes:

• Front travel brake handle ZP 01.000.1.2
• Steering sprocket ZP 01.402
• Fastening elements

Using the band principle allowed engineers to get rid of one of the most unreliable parts of the old kinematics - the gear stopper spring. On classic units, this spring constantly broke, flew off from operational vibrations, or simply got lost, causing the steering strut to lose its fixation. The new band system requires no external springs at all - the metal brake strip itself possesses sufficient natural elasticity. When the operator releases the screw tie rod, the band independently unclamps and smoothly moves away from the drum, and course retention is based entirely on the rigid mechanics of the thread.

Because the band-tightening process depends entirely on the travel of the control handle's threaded rod, operators often raise a logical question regarding the performance of such an assembly under heavy dust conditions on the threshing floor. The mechanism is designed taking these agricultural realities into account - the thread profile and technical clearances between the tie rod parts prevent grain dust or fine debris from compacting tightly inside the turns. Even if dust inevitably settles on open sections of the thread, it cannot cause critical jamming. The natural self-locking property of the threaded pair ensures that the clamped band will not loosen from vibrations, and the adequate leverage of the handle itself allows the operator to easily overcome the resistance of contaminated threads when unbrakes are applied. All of this preserves overall steering smoothness and makes the assembly fail-safe even with minimal maintenance.

Buy Band ZP 01.000.1.3 and Other Retrofitting Components

At Zavod Moroza, you can order the ZP 01.000.1.3 brake band either as a separate replacement item for routine maintenance or complete with all necessary kinematics - the screw handle and the steering sprocket with a drum. Ordering parts directly from the manufacturer ensures the precise geometry of the metal strip and its correct, distortion-free fit against the working surface.

If you decide to abandon the outdated gear stopper on a classic grain loader and convert it to a band brake system, we will assemble a ready-to-install kit for you. Upon separate request, we will include a special metal mounting pad - it is enough to weld it to the old frame in the appropriate place to provide a proper base for the screw tie rod's operation.

At the same time, it is important to rationally assess the overall condition of your equipment. When the frame's metal structure and running assemblies of an old unit show critical wear and signs of metal fatigue, endless targeted modernizations lose their engineering and economic sense. In such cases, we suggest updating your machinery fleet and switching to our modern ZM-60U, ZM-90U, or ZM-120U series machines - in these grain loaders, convenient stepless course fixation, reliable drives, and a balanced undercarriage are already implemented in the base factory architecture.

Contact our sales department for component selection - we understand the steering mechanisms and other assemblies of grain loaders across various production years and will help you find parts and repair solutions that are guaranteed to fit your specific unit.
