Maintenance contracts are one of the easiest line items to strike out of a budget: a certain cost against an uncertain benefit, and the benefit — a breakdown that did not happen — never appears in any report. Here is the arithmetic set out honestly, including the cases where an annual maintenance contract genuinely does not pay.
The number most buyers never calculate
Before comparing maintenance options, establish one figure for your own plant: the cost of one stopped hour in the area the equipment serves. It has four components — lost contribution (output not produced, valued at contribution rather than sale price); idle labour (operators and anyone downstream who runs out of material); recovery cost (overtime, expedited freight, a weekend shift); and consequential cost (delivery penalties, a missed vehicle, an audit finding).
In most SME operations this is higher than assumed, because the last two components are invisible until you look. Once you have it the question is arithmetic: how many stopped hours must a contract prevent to pay for itself? Often one or two a year.
What breakdown maintenance really costs
Running to failure looks cheap because the invoice arrives only when something breaks. The full comparison differs:
| Dimension | Run to failure | Planned maintenance |
|---|---|---|
| Timing | Whenever it happens — typically peak load, month end | Chosen: shutdown day or planned window |
| Diagnosis | On arrival, under pressure, sometimes twice | Scheduled, with condition recorded over time |
| Spares | Whatever is fastest, at whatever price | Correct part, ordered ahead, at list price |
| Collateral damage | Common — a failed seal contaminates a system | Contained — wear item replaced in time |
| Production impact | Full unplanned stoppage | Little or none |
| Cash profile | Lumpy and unpredictable | Budgeted and even |
The dominant term in that table is almost never the labour rate — it is the timing and the collateral damage.
What a maintenance contract actually contains
The Indian market broadly offers two structures, and confusing them is a frequent source of dispute:
- Non-comprehensive (labour-only) AMC. Scheduled visits, inspection, adjustment and labour included; spares billed as used. Lower fee, variable total. Suits equipment with predictable, low-cost wear items.
- Comprehensive AMC. Labour and specified spares included, usually excluding consumables, batteries, tyres and misuse damage. Higher fee, predictable total. Suits high-duty equipment and operations that value budget certainty.
Either way the contract should state in writing: visit frequency, breakdown response time, what is included and explicitly excluded, spares pricing, whether a standby unit is available for extended repairs, and what documentation is handed over after each visit. A contract that does not commit to a response time is a discount scheme, not a service agreement.
Spares lead time is the hidden variable
The most expensive breakdowns in Indian plants are rarely complex. They are simple failures where the part took eleven days to arrive. Equipment origin therefore matters commercially: a machine supported by a domestic manufacturer with stock and a service network returns to service faster than an imported unit whose spares clear a port first. Ask three questions of any contract — which parts are in stock, what is the committed lead time for those that are not, and can a small critical-spares kit sit on your own shelf? Seals, wheels, a control switch and a hose cost little and remove the commonest cause of a multi-day stoppage.
The wear items that decide your year
Most failures come from a short list of components with predictable lives. A contract earns its price largely because someone looks at these on a schedule rather than when they fail.
| Item | Typical symptom when worn | What it becomes if ignored |
|---|---|---|
| Hydraulic seals | Drift down under load, weeping at the ram | Sudden loss of lift; oil on the floor |
| Hydraulic oil | Discoloured, sluggish when hot | Pump and valve wear — cheap fluid killing an expensive assembly |
| Load and steer wheels | Flat spots, higher push effort, noise | Bearing failure, damaged floor, strain claims |
| Chains, ropes, sprockets | Elongation, stiff links, broken strands | The failure mode with the worst consequences |
| Brakes and limit switches | Longer stopping distance, inconsistent stop | Collision damage and injury risk |
| Battery and connections | Short run time, hot terminals, corrosion | Premature replacement — often the largest unplanned bill |
| Structure and welds | Hairline cracks, distortion, elongated pin holes | Progressive failure, expensive or impossible to repair |
Indian conditions shorten several of these intervals. Monsoon humidity accelerates corrosion at terminals and unpainted surfaces; textile lint and paper dust pack into brake assemblies and cooling paths; high ambient ages hydraulic oil and increases water loss in flooded batteries. A calendar copied from a temperate-climate manual will be too slack for most Indian plants.
A three-year worked comparison
Take five semi-electric units in a two-shift operation, in notional units so the structure is visible without pretending to precision nobody has.
- Option A — no contract. Zero fixed cost; seven unplanned failures over three years at 1.0 unit of parts and call-out each and 5 hours of stoppage each. Total 7.0 units of parts, 35 hours down.
- Option B — comprehensive AMC. 1.4 units a year, 4.2 over three years. Scheduled attention prevents four events and shortens the other three to 1.5 hours because the right part is on the shelf. Total 4.5 hours down.
On parts and fees alone the options are close: 7.0 units against 4.2. The decision is made by the 30.5 hours of avoided downtime, multiplied by your cost of a stopped hour. At even 0.2 of a unit per stopped hour, the contract is ahead by roughly six units over three years. If your line is easy to catch up and a stopped hour costs almost nothing, the contract may not pay — a legitimate finding, not a failure of the method.
Safety and statutory obligation
Employers have statutory duties around the safe condition, inspection and testing of lifting appliances, and inspectors, insurers and customer auditors all ask for the same thing: documented evidence of competent examination at a defined interval. A contract generates that record as a by-product. Buying one purely for the paperwork is the wrong reason; not having it when an incident occurs is far more expensive than the contract ever was.
When a maintenance contract does not pay
An honest assessment includes the cases against:
- Very low duty. A single manual pallet truck used a few times a week needs greasing, an annual inspection and a spare seal kit — not a contract.
- A capable in-house team. Plants with their own fitters and a working preventive schedule may need only a spares arrangement and an annual expert inspection.
- Equipment approaching replacement. Comprehensive cover on a machine you intend to retire within a year is money better spent on the replacement.
- Non-critical, redundant units. If another unit simply takes over with no output impact, your cost of a stopped hour is near zero and the arithmetic says so.
The right structure is often mixed: comprehensive cover on the two or three assets whose failure stops production, labour-only on the rest.
How to evaluate an AMC quote
- Preventive visits per year, and what is done at each.
- Committed breakdown response time in hours, with the working-hours definition.
- Exactly which parts are included and which excluded.
- Spares discount and committed lead times for non-stock items.
- Whether a standby unit is available if a repair runs long.
- Written condition report after every visit.
- Operator training or refresher sessions.
- Escalation contact if the response commitment is missed.
Score the quotations against those eight points before comparing annual fees. On the first day it matters, the cheapest contract that commits to nothing is more expensive than the dearest one that commits to a four-hour response.
