Lippmann is the only crawler chassis manufacturer with its own unique chassis design. The TRC (torsional resistant module chassis) was developed from scratch and is backed by 22 years of operating success.

Many modern-day crawler manufacturers lack crawler expertise. They have not dedicated the time required to engineer a chassis designed to be free from catastrophic failure, which is too often prevalent. When copying each other’s chassis design, each manufacturer tried to reduce the weight in an effort to produce the shortest, lightest and narrowest crawler unit, in order to capture the majority of the aggregate and recycling market.

They forgot the fundamentals. “A crusher is a wrecking machine” not an ornament!

At Lippmann,this fact has been preserved and molded around the fundamentals of crushing, incorporating a proven range of Jaw and Impact Crushers in production for the last 22 years.

Key Advantages of the Lippmann L3252 Mobile Track Jaw:

By combining the TRC chassis system, the TPT, and the powerful Lippmann Jaw, the revolutionary Lippmann Mobile Track Jaw Crushing system was born.

What sets this system apart from any other on the market is the sheer size and weight of the Lippmann 32”x52” Jaw in a totally mobile crawler chassis system!

The size of the jaw necessitates little or no preparation of the material prior to crushing. The unique Lippmann Jaw is an overhead eccentric type jaw crusher that does not rely upon gravity alone to move material through the chamber. Instead, it provides a forced-feeding action, which results from the inward and downward eccentric movement of the swing jaw. Longer jaw dies, a larger eccentric, and a non-choking design also mean a reduction in nip angle, resulting in a more positive bite and an ability to devour material unlike any rival jaws in its class.

The TRC chassis system is unique to Lippmann and was the first and only system of its kind.

1. Unique features of the chassis include fabrication from carbon steel which is hot rolled square (not rectangle). This square hollow section withstands “symmetrical loading” and is equally strong through the vertical and horizontal plane of its structure, unlike other structures such as I beams, which can only take maximum load on the vertical.

2. All beams are fabricated ensuring the verticals and the horizontals are equal in dimension at the point of the weld penetration. At every 90 degree joint we include an additional haunch of equal proportion to the vertical and horizontal. This joint ensures maximum gradual load dispersal.

3. The chassis is comprised of two mirror image side frames, tied together with a total of 9+ cross members. This ensures complete rigidity in the chassis structure, eliminating horizontal and lateral movement during (a) tracking and (b) processing, doing away with fatigue caused by excess movement and vibration. This forms a rigid structure upon which to mount the jaw itself, without inflicting further stress throughout the jaw’s structure. Our competition mainly uses the jaw box as the tie-brace between the chassis frames. Lippmann does not, as this causes excess vibration through the main frame bearing housing of the jaw,

potentially leading to bearing failure, jaw box fatigue resulting in catastrophic main frame failure, or damage under the feeder area of the main chassis. This common failure, in many chassis designs, only weakens with repeat repair, eventually rendering the chassis useless.

4. Finally, Lippmann ties the gearbox housing of the track frames to the chassis module. This eliminates the desire of the frames to go their separate ways when they are used to sprag (change direction) during travel, unlike excavators that can use their boom and arm to manipulate directional change. A track-mounted crusher must resemble the characteristics of a bulldozer, which must change direction under severe load in the boggiest of conditions. Notice that the final drive housings in a bulldozer are also locked into the superstructure of the dozer, a few simple yet critical design practices adhered to by Lippmann in its chassis design.

In addition,our TPT (Triple Power Match system) has also been designed through foresight! Where others have taken the economical shortcut by sacrificing and reducing the output of jaw crushers, as predominantly foundin crawler jaw plants which are hydraulically driven, Lippmann has not!

Historically and currently, our wheel-mounted portable crushing plants are mechanically driven through electric motors, or in the case of diesel direct drives, through clutch drives.

With the emergence of track-mounted units, this presents difficulties for any manufacturer who wishes to develop a crawler system, as a diesel engine has only one rear takeoff capable of delivering 100% of power output.

Lippmann developed the TPT, which allows 100% of the engine power from two rear output points. 100% power to the hydraulic pumps in open loop circuit to power the tracks in travel, yielding grade ability up to 11 degrees. Also, this allows long periods of travel without fatigue. In process mode, this unit allows 75% of the power to drive the jaw, and the remainder to power the hydraulics, infinitely variable in speed of function. So the feeder can be varied without disturbing the crushing or conveying functions. This is achieved through radio control from up to 300 yards, or manually, in case of emergency or for maintenance.

To conclude, there are numerous features which make the Lippmann Mobile Track Jaw crushing plant destined for extraordinary success. But the fore mentioned points are the main and key advantages which can be customized to meet specific needs, while maintaining commonality of parts.

Our philosophy is, “Original thinking outside the box.”
