Front Travel ZM-60/60A (ZP 01.020) Assembly

Front Travel Assembly ZM-60/60A (ZP 01.020)

The front travel assembly ZP 01.020 is a critical component of the running gear of the ZM-60 and ZM-60A series grain loaders and their modifications. It is mounted directly to the machine frame and serves as the support point for the front section of the unit, ensuring its stability during operation and travel. The design of the assembly allows steering the machine's direction of movement via the steering mechanism (handwheel), contouring the topography of the working surface (threshing floor), as well as converting the grain loader from working to transport position and vice versa.

Structurally, the front travel assembly ZP 01.020 is a complex metal unit, based on an outer and an inner yoke, a height adjustment mechanism, and a rubber-tyred support wheel. The outer yoke is equipped with special vertical slots where the wheel axle ZP 01.601 is positioned - this solution allows the axle, together with the inner yoke, to shift upward or downward relative to the assembly during position changes and unit movement. This, in turn, implements the surface contouring mechanism, where the assembly compensates for height variations and irregularities of the working area (threshing floor), helping to maintain the correct operating position of the scraper feeders during grain pickup.

The mechanism for height adjustment (lifting) of the front travel assembly ZP 01.020 is implemented via a vertical screw, where the screw drive is actuated by the reciprocating motion of the drive handle. A pawl is installed on the handle, which engages with a ratchet wheel (star wheel) rigidly fixed to the screw. Depending on the position of the pawl (flip-over mechanism), this movement of the handle rotates the screw in one direction or the other, causing the lowering or lifting of the loading feeders along with the entire front section of the unit. Steering is performed via a large sprocket located at the top of the travel assembly, which receives rotational torque via a chain drive from the sprocket shaft on which the steering handwheel is mounted.

Technical Specifications of the Front Travel Assembly ZM-60/60A (ZP 01.020)

Given the long history of production by various manufacturing plants, several design modifications of the assembly exist, with the primary differences relates to the lowering and lifting mechanism. For instance, the large steering sprockets may differ in outer size (although the chain pitch always remains identical), and depending on the version, either a massive bearing housing or a special large nut can be installed beneath it. Different designs of the outer yoke platform are also encountered - ranging from a standard one to variants with a large welded shroud. The shape of the inner yoke may also have visual differences, though its geometry and working slots remain standard. The support point of the vertical screw is implemented differently - it can either rest against a bushing with washers and a pin, or be supported by a full-fledged thrust bearing with a system of bushings. Despite such a vast diversity of designs, our specialists thoroughly know all these nuances and will assist you in selecting the correct spare parts specifically for your grain loader modification without any trouble.

We recommend using our improved modification of the front travel assembly ZM-60U with dual wheels, which comes as standard equipment on all new grain loaders of our manufacture. Installing two wheels on a single axle instead of one significantly increases the overall stability and operational safety of the heavy unit. This solution substantially improves maneuverability under manual steering and adds comfort when moving the grain loader across the working area. Even weight distribution also ensures smooth travel and ease of rotation of the steering mechanism, allowing the operator to position the machine more precisely without unnecessary physical effort. Importantly, this assembly is fully interchangeable with the classic single-wheel variant - it can be easily installed on any ZM-60 grain loader of previous production years without any issues.

Front Travel Assembly ZM-60/60A (ZP 01.020) and Its Components

The proper working condition of the ZM-60 front travel assembly is the key to easy handling and the overall stability of the grain loader. Wear of its elements - from the steering sprocket and screw to the yoke slots - significantly complicates the maneuvering of the heavy unit and its position adjustment. At the Zavod Moroza, you can purchase both a completely ready-to-install complete assembly and all the necessary spare parts for its repair:

• Outer yoke ZP 01.050
• Inner yoke ZP 01.040
• Rubber-tyred wheel ZPT 1.6.2
• Screw ZP 01.070
• Special nut ZP 01.101
• Sprocket ZP 01.402
• Handle ZP 01.060
• Pawl ZP 01.401
• Axle ZP 01.601
• Wheel hub ZPT 1007
• Cap 3S 4040
• Special bolt ZP 01.602
• Bushings (including roller bushings), plates, bars, springs, washers, bolts, nuts, pins, cotter pins, grease nipples, and other small elements of this assembly

Considering the large number of factory variations and the equipment modernization needs, in addition to standard parts, we offer a wide selection of alternative and heavy-duty components. Depending on the design of your unit, various configurations of housings and thrust bearings, steering sprockets of other sizes (including those equipped with grease nipples) are available in our product range, and for specific grain loader modifications, we have elements for a band brake system (instead of the standard locking device on the frame). To increase the machine's cross-country capability on uneven surfaces, the standard 400-mm support wheel can be replaced with an enlarged 500-mm one (from OVS grain cleaners). In this case, if necessary, a corresponding modification of the inner yoke is performed - this guarantees that the travel range of the position adjustment mechanism will be sufficient for the correct lowering of the feeders to the very surface of the threshing floor. To improve the ergonomics of the assembly, we also offer extended drive handles, which significantly ease the process of adjusting the height of the front section of the frame, and modern wear-resistant metal-ceramic bushings, which serve as a reliable and more durable alternative to classic roller ones.
