Repairs on all Hydraulic Cylinders.
Refurbishing on all Hydraulic Cylinders.
Manufacturing on all Hydraulic Cylinders.
We have a wide variety of HiTech, Volvo, CAT, Sumintomo, Bell, Komatsu, Kawazaki and Liebherr Cylinders on Exchange.
We refurbish and repair these components to OEM specifications, with new springs if necessary.
We repair cracks, broken off ears and hoses
We also sandblast and stress relief componnets after major repairs, like lifting new plates, etc.
We manufacture complete new buckets, minor and major repairs for instance new cutting edges, leading edges, wears trips hanger brackets and line boring off bucket holes.
We manufacture harden and ground pins and bushes to OEM specifications.
Straightening on A-frames, weld, line bore and machine damaged bearing areas and also replacement of badly worn bearing hoses.
We weld and line bore all kind of H-frames, back to standard OEM specifications. We also manufacture and fit bushes all to OEM specifications. In some cases we also remove the old torque tube and fit new ones. We also weld and machine badly worn faces with facing attachments tool on site and in-house.
We do on site line boring both local and cross border. We have fully equipped quantum vans and both are fitted with generators enabling us to work almost anywhere.
We got a Lincoln welding, gauging and generator combination machine that allow us to gauge and weld on site, with the correct amps and penetration. required to do proper repairs on site.
We have skilled artist on all our machines that allow us to do almost any fabrication and general engineering that the customer may require.
U&L are committed to rebuilding undercarriage related components to
the highest standards that go the distance and provide genuine savings.
To ensure U&L Track frames and components meet our rigorous new parts standards of quality, individual parts are manufactured both globally and locally to OEM specifications. All engineering, assembly and quality assurance is carried out by U&L Engineering and checked by their qualified Engineering Department.
We supply all our track frames complete with idlers and rollers on a service exchange basis.
Caterpillar D9, D10 & D11
Komatsu 375 & 475
With a dedicated QA & Engineering department as well as an expertly designed new assembly
area for component builds, U&L Engineering fit U&L approved parts, repair and assemble to strict
standards. Thanks to their innovative production process, our JV track frames are the highest
degree of reliability and value.
U&L supply New and reconditioned track frames and components to many local and
international organisations across a variety of mining sectors. We’ve partnered with our clients
to create innovative undercarriage solutions which extend wear life and increase productivity
through reduced downtime.
01 Strip, clean and assess the condition and scope
of work required for the remanufacture/ repair
of the track frames. This includes sand blasting
and Non-Destructive Testing (NDT).
02 Strip the telescopic section, ensure the condition
of the recoil spring.
03 Strip the slack adjuster and assess.
04 Remove and replace the chrome sleeves.
05 Repair, manufacture or supply parts to OE
standards and reassemble.
06 Assess all major and minor bogies.
07 Repair all damaged areas. This will include
the buildup and restoration of the track guide
mounting area, the removal and/or repair of
roller and idler cap bolt holes on both major
and minor bogies. The line boring and repair of
major and minor bogies where bogie pins have
collapsed and damaged the bores. All these
repairs are done to the highest standards and
tolerances.
08 The complete frame is extensively checked
for cracks. If found these are repaired and
reinforced.
09 The base of the frame where the resilient pads
are mounted are given particular attention as
this may indicate inner tube cracking. If the case
the belly plate is removed, the tube repaired,
and a new belly plate fitted.
10 The front sealing area is checked. If damaged
this area is pre-machined, built up and machined
to original specification.
11 Pivot shaft bores, the split bronze on steal
bushes are removed and the bores checked. If
not within specification, the holes are built up
and line bored to standard.
12 The equalizer bar mounting holes are built up
and line bored.
13 U&L has a minimum standard repair parts kit
that includes mining quality bogie pins, seals,
retaining rings, wear parts, covers, nuts, bolts,
guards, resilient pads, guides, plugs, rollingstock
caps, rollers and idlers. (This list is available on
request)
14 Once all parts are ready, the assembly process
starts. A variety of hydraulic equipment and jigs
are utilized for the assembly process depending
on the size and type of track frame.
01 Special tooling and dies are used to ensure the
careful assembly of the bogie system and recoil
assembly insertion.
