Push-Pull Unit

A unit consists of a number of modular hydraulic cylinder sub-assemblies. Each module consists of powerful double-acting, double ended hydraulic push-pull cylinders with a clamp assembly mounted on the bottom of the lower piston rod. An adjustable guidance system is surrounding the upper piston rod.The modules are bolted to a support frame. Each module can push with 200 tonnes.

The unit can be configured with 2, 3 or 4 sub-assemblies.

The light blue plates in the sketch shown are support frames, the light grey cylinders the modular hydraulic cylinder assemblies (four shown) and the brown areas packing fabrications to accurately position modules to suit pile centres.

The Piling Rig

Should be able to impart between 20 and 50 tonnes of down-crowd or extraction force to the Push-Pull Unit over the entire pile installation length. Besides, it should be capable of handling the combined weight of the Push-Pull unit and relevant sheet piles.[/vc_column_text][/vc_column][vc_column width=”1/3″][vc_single_image image=”4061″ img_size=”336 x 448″ alignment=”center” title=”Push-Pull System Set-up”][/vc_column][/vc_row][vc_row][vc_column][vc_separator color=”pink”][/vc_column][/vc_row][vc_row][vc_column width=”1/3″][vc_column_text]

Advantage by Leader Articulation

The leader of the piling rig should have the ability to articulate or pivot in plain view.

This feature results in two signiﬁcant operational beneﬁts:

The operator can position the leader for good visibility with minimum track movement.
With 2-Cylinders the Push-Pull Unit can accomodate numerous pile proﬁles simply by lead articulating and adjusting the rotationel setting of the individual cylinder assemblies.

The examples in the sketches show the same 2-Cylinder Push-Pull unit working with Arcelor AZ18 and PU32 sheet piles. The centres of the two Modular Hydraulic Cylinder Sub-Assemblies remains the same, but the Adjustable Guidance System is altered to correctly align the Clamp Assemblies with the clamping faces of each pile.[/vc_column_text][/vc_column][vc_column width=”1/3″][vc_single_image image=”4056″ img_size=”336 x 433″ alignment=”center”][/vc_column][vc_column width=”1/3″][vc_single_image image=”4055″ img_size=”336 x 426″ alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_separator color=”juicy_pink”][/vc_column][/vc_row][vc_row][vc_column width=”1/3″][vc_single_image image=”4062″ img_size=”336 x 448″ alignment=”center” title=”Two-cylinder Push-Pull”][/vc_column][vc_column width=”1/3″][vc_column_text]

Main Advantages by the Push-PullSystem

Vibration-less and quiet.
Fast installation and extraction due to the high push-pull force up to 200 tonnes.
Ready conﬁgured to suit Z, U and H-pile proﬁles in groups of between 2 to 6.
No reaction frame required to start pile installation – unlike conventional pile press.
Corner piles easily installed without reaction frame.
Standard Z-piles can be installed close to property boundaries.
Leader guided operation reduces interlock friction and produces accurate installations.
Piles can be threaded without the use of a crane.
Piles can be removed to leave the area to the original condition.
The Push-Pull can be configured to install high capacity foundation piles formed by interlocking 4, 5 and 6 sheet piles in a box.
