What Latin American mine managers should consider when comparing TCA-7, TPB-40, TPB-60 and TPB-90.

A mine can contain several different working environments within a short distance. A narrow access route may lead to a confined underground heading, while a nearby surface area provides room for heavier breaking equipment.

For purchasing teams, this creates an important distinction: the most suitable pneumatic breaker for one location may serve a different purpose elsewhere on the same site.

Terrain provides the starting point. The final choice should bring together access, operator position, rock condition and the size of the breaking task. This gives Latin American mine managers a practical way to assess the Shenli Tools TCA-7, TPB-40, TPB-60 and TPB-90.

Mountain Access Routes: Consider Every Equipment Move

For hillside workings and remote mountain projects, begin with the route between the equipment store and the prepared work area.

How often will the crew relocate? Can equipment be transported close to the job, or must operators carry it for part of the journey? Will the task involve small areas of material removal or repeated breaking at one position?

The TCA-7 is a candidate for light, localized work where its intended application matches the material. The TPB-40 provides another option to evaluate when the work calls for a larger breaker while retaining a more manageable handling weight than the heavier TPB models.

The objective is to match the tool to the complete assignment, including movement between work points. Mountain terrain alone does not determine the required breaking capacity.

Confined Underground Areas: Match the Tool to the Available Space

Inside a narrow working area, check the space needed for the operator, tool, chisel and air hose.

For localized soft-rock work or small trimming tasks, the TCA-7 is worth assessing. Where a more substantial breaking task is planned and sufficient clearance is available, the TPB-40 can enter the comparison.

Before ordering, confirm the intended working direction and the space required to position and withdraw the chisel. Tool length and handling arrangement should be checked against the actual work location.

This approach helps procurement teams distinguish between a compact tool for selective work and a larger breaker for a prepared, more accessible position.

Open Benches and Surface Work Areas: Assess the Breaking Task

On a prepared surface bench, equipment access may allow the mine to consider a wider range of breaker sizes.

For substantial blocks or heavier localized breaking, the TPB-60 and TPB-90 are candidates for assessment. Selection should consider block dimensions, fractures, access to a free edge and the direction in which the material can separate.

The TPB-60 may be evaluated for a work package requiring a heavier breaker, while the TPB-90 can be assessed for more demanding tasks supported by suitable handling and air-supply arrangements.

A larger model should be selected because the job benefits from its capabilities. Mine size or the appearance of the surrounding landscape is not enough to establish the right choice.

Fractured Ground and Mixed Material: Look Closely at the Break Point

Two nearby work areas can require different tools even when both are described as hard-rock terrain.

One may contain smaller, fractured pieces that can be approached from an exposed edge. Another may involve a larger, more intact block with fewer accessible breaking points.

For the first task, a TPB-40 may be worth testing before specifying a heavier model. For the second, the TPB-60 or TPB-90 may merit evaluation.

A representative trial should examine useful material removal, repositioning effort and chisel suitability. These observations provide a stronger purchasing basis than selecting a model from rock hardness alone.

Use Weight to Plan Deployment

Published net weights provide a useful reference when planning handling:

Model	Published net weight	Initial selection focus
TCA-7	7.2 kg	Light, localized work in suitable material
TPB-40	18 kg	General localized breaking with attention to mobility
TPB-60	30 kg	Heavier breaking at prepared, accessible positions
TPB-90	42 kg	Demanding breaking tasks with appropriate support arrangements

These are starting points for assessment, rather than guaranteed application limits. Confirm the supplied configuration, chisel and intended use with the supplier.

Connect Terrain Selection With the Air Supply

The location of the work also affects how compressed air reaches the tool.

A breaker working near a surface supply point has a different hose arrangement from one operating farther along an underground route. Include hose length, connections and simultaneous tool use in the equipment review.

For high-altitude mines in the Andes, provide the compressor supplier with the actual elevation and operating conditions. Confirm the air available to the selected breaker while it is working.

Stable footing and a prepared operating position remain essential for every model; a terrain-based selection does not replace the mine’s ground-control and access procedures.

Purchase for the Mine’s Actual Mix of Work

A mine with varied tasks may benefit from assigning different breaker models to different work packages.

A lighter unit can serve suitable selective tasks, while heavier models can be allocated to prepared locations requiring greater breaking capability. This allows the purchasing team to organize equipment around the work crews actually perform.

When requesting a recommendation from Shenli Tools, include photographs of the work area, access dimensions, material condition, typical block size, working direction and available air supply.

Together, these details make it easier to develop a practical model shortlist for your mine.
