What counts as “mobilised”?
Delivery, placement, installation and “air available” are different events with different owners. A compressor delivered without its dryer may satisfy the transport milestone and still fail the production requirement. Agree one set of definitions across the rental order, the transport booking and the plant shutdown schedule:
- Dispatched: the full package has left our yard with its documents.
- Delivered: it has arrived and been checked at site.
- Placed: it is in its final position, levelled, with clearances for cooling and service.
- Connected: hoses, treatment, power or fuel are in place.
- Air ready: required pressure, flow and quality have been shown at the receiving point.
Work backwards from “air ready”. Include inspection, connection, electrical checks or fuel arrangements, time for the dryer to reach dew point and a controlled transfer. If the existing station must be isolated to make the connection, put that outage in the schedule explicitly. Our page on tie-in and changeover covers the transfer itself.
Build a complete equipment and accessory list
Most mobilisation delays come from a missing small item, not the compressor. A full list for a typical temporary station includes:
- compressors, with their rated flow and pressure and whether diesel or electric;
- aftercoolers, moisture separators, dryers and filters needed to reach the required air quality;
- receiver, where the site has no usable storage;
- hoses with the correct diameter, length and pressure rating, couplings, whip checks and adaptors to the plant connection;
- manifolds, isolation valves, gauges and drain fittings;
- for electric units: cable of the right size and length, a suitable incoming isolator and earthing arrangement;
- for diesel units: fuel arrangements, a drip tray or bunding where the site requires it;
- a starter set of consumables and the service kit for the planned hire duration;
- documents: delivery note, pre-dispatch check record, operating instructions and contact numbers.
Check the list against the actual plant connection, not a generic one. Photographs of the tie-in point save wrong adaptors.
Match transport to the real package
Plan transport for the package as it will actually travel, with dryers, hoses and accessories, not just the compressor’s brochure weight. The table shows the usual options for the equipment we supply.
| Equipment | Typical transport | Points to confirm |
|---|---|---|
| Portable diesel 100–600 cfm on wheels | Towed by a suitable vehicle, or carried on a truck for long distances | Towing eye and brakes in order, tyres, lights; towing speed limits; road suitability over long distances |
| Larger diesel packages and high-pressure units (above 600 cfm, up to 30 bar / about 435 psig) | Flatbed or low-bed truck | Lifting points, crane or forklift at site, height on the vehicle under bridges and cables |
| Skid-mounted electric compressors and dryers | Truck with crane, or truck plus site crane or forklift | Forklift pockets or lifting lugs, protection of panels and dryer vessels from knocks and rain |
| Hoses, manifolds, cables and small items | Same vehicle where possible, or a separate light vehicle | Packed and labelled so nothing is left behind or separated from the main load |
A towable compressor is not automatically suited to every distance or route. For long highway journeys across states, or roads in poor condition, carrying the unit on a truck is often safer for both the machine and other road users.
Survey the route and the site access
Before dispatch, confirm with the site team:
- gate width and height, turning space for the vehicle, and any time restrictions for heavy vehicles entering the city or the plant;
- overhead cables, pipe racks and canopies on the route inside the site;
- ground conditions at the placement point: hard standing that will carry the weight, not loose fill that softens in the monsoon;
- slope, drainage and the risk of standing water around the package;
- distance from the placement point to the plant connection, which sets hose length and pressure drop;
- clearances around the package for cooling air, exhaust discharge away from buildings and air intakes, and service access.
In Indian summer conditions, with ambients of 40–45 °C and above 45 °C on open sites, avoid placing a compressor where it will breathe its own hot exhaust or sit against a hot wall. Shade and a clear air path matter.
Unloading, placement and securing the load
Agree in advance who provides the crane or forklift, who is the competent person for the lift, and whether a lift plan is required by the site. Use the package’s designated lifting points only; dryers and control panels are easily damaged by improvised slings.
For transit, the package should be prepared so it arrives as it left:
- drain or secure fluids as required, and close tank caps and service doors;
- cap open hose ends and pipe connections to keep out dust and water;
- secure the unit to the vehicle with suitable restraints, and pack loose items so they cannot shift;
- record the condition with photographs before departure.
On arrival, inspect the load before restraints are released. Check for transit damage, fluid leaks and loose items, and compare against the equipment list. Record any shortage straight away so it can be sent before it delays the connection.
Sequence deliveries and protect cleanliness
When several items arrive, the order matters. The machine that will sit furthest from the access road usually needs to go in first. Hoses and manifolds should arrive with or before the compressor, not after. Where a site crane is booked for a short window, all lifted items need to be there for it.
Keep the air path clean during installation. Open hoses left on the ground collect dust, insects and water, which then go straight into the plant header. Keep caps on until connection, blow hoses through before connecting them to the plant, and fit filters before any sensitive user.
Which activities really control the finish time?
In practice, the items that most often hold up “air ready” are:
- the plant connection itself, where an outage or a hot-work permit is needed;
- electrical supply for electric units: cable routing, termination and checks by the site electrician;
- dryer start-up and the time to reach dew point;
- site permits, gate passes and safety induction for our crew;
- a crane or forklift that is not available when the truck arrives.
Report these as separate items rather than a single “percentage complete” figure, which can hide the one open item that will stop the job. If a deviation occurs, such as a substitute machine or a different hose route, check it against the original duty: flow, pressure, quality and continuity at the receiving point still have to be met.
Weather, distance and disruption
Monsoon rain, flooding of low-lying access roads and extreme summer heat all affect mobilisation in Telangana and Andhra Pradesh. Plan for them:
- have tarpaulins or covers for panels and dryers during unloading in rain;
- avoid placing packages in low spots that collect water;
- allow for slower movement on long routes and check for road restrictions;
- for remote or long-duration sites, arrange fuel supply and service visits before the job starts, not after.
Compare options on schedule risk as well as transport cost. A slightly more expensive transport that guarantees arrival before the shutdown starts is usually cheaper than a delayed restart.
How Reddy Compressors helps
Reddy Compressors, based at Tarnaka, Secunderabad, since 2002, runs its own rental fleet of diesel and electric compressors, 50–2,000 cfm and 2–30 bar, including high-pressure units, with hoses, dryers and accessories. We are an independent multi-brand specialist and supply, rent and service ELGi, Atlas Copco, Ingersoll Rand, KAESER, Chicago Pneumatic and other makes, without acting as an authorised dealer for any of them.
For mobilisation we prepare the package and its accessory list, check it before dispatch, arrange transport, and send our crew to place, connect and commission the station with your team. Our service teams cover all of Telangana and Andhra Pradesh, and we supply rental equipment across India, with project-based site support where feasible. One example of our work: for a natural-gas development project at Kakinada, our team supplied, transported, erected and commissioned a temporary package of six compressors from 750 to 1,100 cfm, generators and distribution boards, with operators and a technician on site.
What to send us
- Site address and a location pin, with any vehicle or timing restrictions.
- Required flow, pressure and air quality, and the hire duration.
- Photos of the placement area, access route and plant connection point.
- Whether you can provide a crane or forklift, and power supply details for electric units.
- The date and time air is needed, and any shutdown window it must fit.
- A site contact who can receive the delivery and arrange permits.
Frequently asked questions
How do you transport a rental air compressor to site?
Smaller portable diesel compressors on wheels can be towed for short distances on suitable roads, but for longer journeys they are usually carried on a truck. Larger diesel packages, high-pressure units and skid-mounted electric compressors and dryers go on a flatbed or crane truck. The choice depends on the weight and size of the full package, distance, road conditions and the unloading equipment available at site.
What should the site prepare before a rental compressor arrives?
Prepare firm, level hard standing with drainage, clear vehicle access and turning space, and enough clearance around the package for cooling air and service. Arrange gate passes and inductions for the crew, a crane or forklift if the package needs lifting, and the electrical supply for electric units. Identify and photograph the plant connection point so that the right hoses and adaptors come with the first delivery.
Why is there a delay between delivery and having compressed air available?
Because delivery is only one step. After arrival the package must be checked, placed, connected to the plant, supplied with fuel or power and started. Dryers need time to reach their dew point, hoses must be purged, and the transfer from the existing system has to be done in a controlled way. Permits, cable work and a crane that is not available are the most common causes of further delay.
Can a portable compressor be towed on the highway?
Many portable compressors are built for towing, with a towbar, wheels and lights, but whether it is sensible depends on the distance, the road, the towing vehicle and the condition of the running gear. For long inter-state journeys, carrying the machine on a truck is often safer and protects the machine from vibration and road damage. We decide this case by case for each hire.
Who is responsible for unloading the compressor at site?
That should be agreed before dispatch. Some jobs use a truck with its own crane; others rely on the site’s crane or forklift. Either way, the lift must be done using the designated lifting points by a competent operator under the site’s safety rules. Tell us what lifting equipment you have and we will plan the delivery to suit it.
Do you supply rental compressors outside Telangana and Andhra Pradesh?
Yes. Our service teams cover Telangana and Andhra Pradesh, and we supply rental compressors, equipment and spares across India and provide project-based site support elsewhere where it is feasible. For distant sites we plan transport, fuel, servicing and spares before mobilisation so that the package can run reliably for the full hire period.
