Preventative Maintenance By Allison Hydraulics Ltd
Preventative Maintenance (PM) is a service that is becoming increasingly
popular especially in today’s industrial market place where there is often no
built-in allowance for breakdowns.
Here at Allison Hydraulics we believe we are
in a superb position to provide PM packages for UK businesses. We have a
dedicated team of experienced hydraulic engineers operating from branches at
Leeds, and Newcastle whose specialist skills are saving companies thousands of
pounds every week.
Companies that opt for a PM package are typically those engaged in the supply
of components to the motor industry and are often working to ‘Just in Time’
circumstances. In recent years we have seen the move towards ‘Just in Time’
supply in many other industries and as a result companies are seeking the advice
of PM specialists for their hydraulic systems. With a visit from one of our
engineers PM packages can be clearly seen as an advantage and that a reputable
company must be appointed for the package to be a success. With 25 years
experience in the hydraulics industry it is no surprise that companies are
turning to Allison Hydraulics for their PM packages.
Essentially these PM packages involve the close and frequent monitoring of
all measurable parameters within the hydraulic system. Most, if not all of these
measurements are taken whilst the machine is still in production and are
non-intrusive. As part of this regular monitoring, oil samples are taken and
inspected for particle contamination. Oil contamination and high oil
temperatures are two of the most common factors that can lead to system failure
and time spent controlling these two areas is time well spent. Surprisingly, one
of the most common causes of oil contamination is that of air borne particles
finding their way into the system through inadequate and sometimes non-existent
tank air breathers. These fine particles can easily clog up filters with
disastrous consequences.
Probably the most important ingredient to operating a successful PM service
is having experienced hydraulic personnel to correctly interpret the findings.
For example, if we discover a machine running at an excessively high temperature
we need to determine the cause of this, it may be an incorrectly set pump, a
relief valve not being unloaded due to a signal fault or just a clogged radiator
on a fan cooler. Generally this sort of diagnosis in not within the capabilities
of the multi disciplined maintenance technician.
Another important aspect of the PM service is that of written reports. These
reports will record all of the measurements taken, thereby giving a history for
comparison and will also show the improvements made to the oil condition and can
be shown in graph form. There will obviously be occasions when corrective work
needs to be carried out to prevent a worsening situation and potential
breakdown. The only way this service can be successful is if both service
provider and customer work in partnership and the customer takes action on the
recommendations of the hydraulic engineer. Generally speaking all parties
involved with the PM packages provided by Allison Hydraulics are pleased with
the results, but only wish they had taken specialist advice sooner to save their
time and money.

Refurbishment At Allison Hydraulics
Since 1975, the company has assisted machine tool companies and press
builders in the restoration of a wide variety of equipment. AHL has replaced
obsolete non-standard hydraulic power packs and components with those to the
latest industry standards. In the press field, on occasion it has been water
hydraulics that has been removed!
Along the way AHL has expanded from being a small independent designer and
manufacturer of hydraulic systems and power packs eventually taking in
electrical and electronic control systems. As more of its products became
established in the market place a service department had to be set up to deal
with essential maintenance. The experience gained has proved invaluable and
given an insight into the design of machinery and the faults it can develop.
The purchase of the old established press manufacturers – Rhodes Gill, in
1992 gave AHL another string to its bow. The increased drawing office capability
and machine shop capacity enabled a whole new range of equipment to be
developed. Also, in addition to carrying out maintenance purely on hydraulics,
electrics and mechanical machinery parts, the company was now in a position to
design and build complete machines for a variety of purposes. To save costs it
could also offer extensive refurbishment services to almost new condition. It is
this latter facility that has seen the growth as large manufacturers have sought
to increase productivity by re-allocating the duties of existing machinery
rather than investing in new.
Among many others, AHL has over the past decade completely or partially
overhauled machines for textile baling, the manufacture of gudgeon pins, meter
casings, scaffolding plank reclamation, steel cable crimping for nuclear power
stations, forging presses for the aerospace industry, heavy vehicle axle
forging, special purpose injection moulding machines, a machine for making and
extruding endless reels of flexible plastic hose, and many others.

Allison Appointed UK Distributor For Italian Press Manufacturer
Locatelli Meccanica Manufacturers
Of Hydraulic Coining Presses Have Agreed To Allison Being their UK Distributor
Locatelli was established
in 1924 and their hydraulic presses, have for many years,
been used in various fields, including gold and silver jewellery,
spectacle frames, watch making, minting and cold metal deforming.
 Allison
Hydraulics Limited who are the latest acquisition to the DCA group, joining
in 1998, was established in 1975. Almost from the beginning Allison were
UK main agents and distributors for Atos and MP Filtri, whose products
are coincidentally widely used on Locatelli presses.
Giulio Locatelli, Export
Manager of Locatelli Meccanica, and Tony Whitehead, founder of Allison
Hydraulics meet at Pudsey. 
Mr Whitehead says: "The new
partnership will provide varied and interesting work for the Allison labour
force, which could eventually lead to new jobs, I'm looking forward to
a long and successful association with Locatelli."
Operating from two sites
in Pudsey and Jarrow Allison not only distribute components but provide
a repair and maintenance service throughout the industry.
At the main works in Leeds
the company designs and manufactures its own hydraulic presses from the
long established Rhodes Gill range. These will continue to be produced
mainly as special purpose presses and sold alongside the Locatelli range.

Allison
engineers operate a delivery service on a regular basis throughout Yorkshire
and the North East. They can now also meet the requirements of companies
operating in JIT circumstances with the extra vans that have been added
to their fleet.
