Standard Cranes


Crane selection - This is often difficult, however time spent analysing your requirements can save you a lot of time and money later. A few basic questions to ask are:

  • How frequently will the crane be used?

  • What temperatures will the Crane be used in?

  • What is the heaviest load the Crane needs to move?

  • Is the heaviest load infrequent and if so is there another way (rollers, etc)?

  • Does the Crane need 4 axis of movement (north-south, east to west)?

  • Does the Crane need 2 speed of hoisting (creep for setting down, fast for clearing)?

  • Does the Crane operate in hazardous areas?

Oiltech offer a range of Cranes categorised as follows:

Bridge crane.

This type of crane runs on an elevated runway system along the length of the factory or working environment.  Bridge Cranes are available in Single girder (MONO) or double girder (DUAL). Double girder is more suited to larger spans.


Gantry crane.

This type of crane is similar to the bridge crane and includes legs at both sides to floor mounted rails.  The gantry

crane shares the same performance as the bridge

crane and is a little heavier, however it may be more

convenient for the rails on ground (or deck mounted).  

A hybrid of the gantry and the bridge would typically

have just one leg; again the performance remains the s



Monorail crane.  

This type of Crane mounts on the underside of the Crain rail and has 2 axis of movement only (along the rail).  This is often the most cost effective solution (being low cost, light and maintenance friendly).  The monorail hoists can lift using chain or wire rope

Oiltech offer a range of standard cranes for all application, see the following Range Data sheets below.

ECH 100.  

Range of Driven Electric Chain Hoists from 500kg SWL to 10000kg SWL.


ECH 200.

Range of Undriven Electric Chain Hoists from

500kg SWL to 10000kg SWL.



Range of Industrial Bridge Cranes from 1250 kg SWL to 50000kg SWL.


BR100-LH MONO.  

Range of Low Headroom Bridge Cranes with single beam bridge from 1250kg SWL to 50000 kg SWL.



Range of Low Headroom Bridge Cranes with dual beam bridge from 1250kg SWL to 50000kg SWL.


Special or Hybrid Cranes at your request.

Oiltech have been designing Cranes since 1981, usually bespoke and to suit the application.  These Cranes include Gantry Cranes, Bridge Cranes, Goliath Cranes, and Semi-goliath Cranes.  Oiltech have also designed Pedestal cranes, King post Cranes, Knuckle boom Cranes, Davit Cranes, Telescopic Cranes.  Oiltech have designed Cranes to handle BOP stacks, LMRPs, BOPs, Xmas trees, Subsea Templates, Manifolds, Lower Marine Risers, Telescopic Joints, Large Casings, Drillcollars, Spuds and just about anything on a rig which needs handling.  We have designed and built to ABS, DNV,NMD, NPD Lloyds, BV, Germanischer Lloyds.  I believe it’s fair to say we know about Cranes, Onshore, industrial or Offshore.  We have built for Oil Companies, Drilling Contractors, Consultants and even for competitors.  Oiltech are Crane specialists.

Moonpool Mechanisation


In the last years BOP Stacks for use on dynamic drilling vessels, have grown considerably.  This includes the mass of the BOP stack, and also the heights and girth have increased. In addition to this safety and maintenance requirements have increased. This means that the equipment handling the BOP stacks have needed larger SWL’s (Safe Working Loads).

In existing dynamic vessels it could also mean that structural modifications are required in the moonpool area, and in some cases the Drillfloor itself has to be raised.

The level of mechanisation will be increased to improve safety.

Oiltech have pioneered a number of products to mitigate the amount of modification work and to comply with the requirements.
