| BLOCK SHEAR is a line of highly-productive portable
hydraulic tools for the masonry and landscaping trades, that provide
on-site, precise split-face cuts on all types of cast and natural
stones, including specifically: 1. Natural Stone
2. Curb Ston
3. Cast-Stone
4. Concrete Masonry Blocks
5. Veneer Stone
6. Mosaic tile
7. Brick Pavers
8. Wall Stone, including the toughest, Granite and Quartzite
BLOCK SHEAR portable equipment vastly increases the speed
of splitting and shaping of large and small stones of all above
types, with large labor savings. Typically, the payback period is
only a few weeks. The increase in efficiency that this equipment
delivers is so significant that it usually pays for the equipment
cost on the first project.
BLOCK SHEAR hydraulic splitters are activated either manually
or Air-assist- Activated. In either variant, it’s the hydraulics
that turn our splitter into power tools, as compared with still
commonly used labor-intensive (manual) block and stone cutting and
splitting methods. Please read on to learn why BLOCK SHEAR portable
machines are the favorite of stone masons and landscapers worldwide.
Our Small Equipment Division focuses on manufacturing hydraulic
tools and equipment for splitting cast stone (masonry), natural
stone and slab construction materials. See above the detailed list
of applicable construction materials.
BLOCK SHEAR™ portable machines -- hydraulic masonry
equipment and hydraulic stone splitting equipment (hydraulic splitters)
– quickly became the favorite of stone masons and landscapers
worldwide.
Our hydraulic stone / block splitters are activated either manually
or as air-assisted activated. In either variant, it’s the
hydraulics that turn our splitters into power tools, as compared
with still commonly used labor- intensive (manual) block and stone
cutting and splitting methods.
Our hydraulic splitters are portable but robust, as are all tools
and equipment designed by Mr. Lackner. LACKNER TOOLS™ represent
good value because they are very practical.
The payback period on BLOCK SHEAR™ portable machines is typically
only several weeks.
In other words, the increase in efficiency and labor savings that
this equipment delivers usually pays for its price on your first
project.
Because of their additional efficiency, Mr. Lackner recommends our
air-assisted hydraulic models for anyone who will use them for just
one medium size project or for repeated small projects.
Selecting the Optimal BLOCK SHEAR™ Equipment:
Broadly, BLOCK SHEAR ™ hydraulic power splitting
equipment is used to:
Split / cut masonry and pavers, or pre-cast construction materials.
Split / cut natural stone and slabs. Models designed for this application
will also
split / cut pre-cast construction materials.
Operation & Benefits of BLOCK SHEAR tools:
BLOCK SHEAR ™ hydraulic power-splitters come in two configurations,
either as Manually-Activated or as Air-Assist-Activated. The later
models can also be activated manually.
All BLOCK SHEAR ™ power-splitters are portable to the job-site.
They are equipped with handcart type wheels.
Manually-Activated Hydraulic Tools:
Manually-Activated BLOCK SHEAR™ tools are self-contained and
provide the highest productivity for splitting natural stone and
masonry products in the industry. At the core of this advantage
lies the BLOCK SHEAR™ designed pumping mechanism.
When the operator places a new stone, block or slab on the worktable,
the first time he presses the (single) foot-lever, the worktable
and the lower cutting blade move up by about 2” [ 50 mm ]
– in one move it fits the upper blade snuggly on the blocks,
stones or slabs being cut. Subsequent pumping of the same lever
drives the hydraulic actuator that quickly splits the construction
material, moving in 1/8” [ 12.5 mm ] increments.
BLOCK SHEAR™ tools are engineered to reduce the pumping
of the foot lever because the first 2'' [ 50 mm ] adjustment is
only available with our unique mechanism.
A BLOCK SHEAR™ Manually-Activated tool is recommended
for jobs that involve the splitting of a small quantity of stones,
masonry blocks, slabs or pavers at a time. For larger jobs we recommend
the BLOCK SHEAR™ Air-Assist-Activated tool.
Air-Assist-Activated Hydraulic Tools
The Air-Assist-Activated BLOCK SHEAR™ equipment adjusts the
position of the worktable and splitting / cutting blades and makes
the cut even faster.
The operator simply squeezes the air trigger - the adjustment of
the table and blades, and the cut follow. Our Air-Assist-Activated
machine requires only a small outside compressor. A portable one
is perfectly adequate. Furthermore, compressors are usually available
on job sites.
As a back-up feature, Air-Assist-Activated BLOCK SHEAR™ tools
include the single foot-lever of our Manually-Activated tools. This
enables these machines to operate even when there is no compressor
around.
Our Air-Assist-Activated BLOCK SHEAR™ tools are recommended
for jobs that require the splitting / cutting of a larger volume
of natural stones, masonry blocks, slabs or pavers.
HYDRAULIC FORCE AND MACHINE THROAT SPECIFICATIONS
BLOCK SHEAR™ Masonry Tools (Manually-Activated and Air-Assist-Activated)
· Produce 24,000 pounds [10,900 kilograms ] of splitting
force, to provide precise split-face cuts, straight cut or angle
cut, on masonry blocks, brick pavers and cast-stone.
· Their throat opens up to 8.25” high by 18.25”
wide [ 210 mm x 464 mm ] to accommodate most pre-cast blocks, pavers
or slabs.
BLOCK SHEAR™ Stone Tools (Manually-Activated and
Air-Assist-Activated)
· Produce even higher splitting force, namely 40,000 pounds
[ 18,000 kilograms ], to provide precise split-face cuts, straight
cut or angle cut, on natural stone or slabs (also on masonry blocks,
brick pavers and cast-stone).
· In Manually-Activated Stone Tools, the throat opens up
to 8.25” high by 18.25” wide [ 210 mm x 464 mm ] to
accommodate most of natural stones and slabs (not to mention pre-cast
ones).
· In Air-Assist-Activated Stone Tools, the throat opens even
wider, up to 8.25” high by 24.5” wide [ 210 mm x 622
mm ].
