Monorail cranes or “goalpost cranes”, or runway cranes, explained.
A monorail crane for warehouse use is similar to an overhead traveling crane (OHTC’s) but the main difference the movement is only on 2 axis. Traditionally the movement on OHTC’s is 3 axis, up/down, left/right, and forward and reverse.
As you can see on the picture below the hoist can only move forward and backwards along the beam, and up and down. This is perfectly normal and is often used in small workshops where space is limited, or where a client only needs to move a load along a straight line. Side pulling is not allowed, and must never happen as it is potentially dangerous to the hoist and more importantly your factory personal.
The length of the run needed is important to know, as this will impact on how many “goalposts” you require along the crane runway or length.
10 things you need to know or ask about monorail cranes, goalpost cranes, or runway cranes.
- What SWL, safe working load do you need to lift?
- How many hoists or hooks do you require on your runway?
- What span to you require, between the goalposts, or overall runway length?
- How high to you need from hook to floor?
- Is it for indoor or outdoor use?
- Do you require electric or manual hoists / chain blocks?
- If electric do you require a pendant control or a radio remote control to operate the hoist?
- Voltage for electrically driven monorail cranes systems in the UK is normally; 3 phase and earth, 415 volts 50hz.
- Will the power be fed from buzz bar where is the nearest isolator and power supply?
- Do you require a full goliath or a semi goliath crane?
