Activity.... Do – Think - Learn
Designing machines to lift heavy loads to great heights and place them accurately is an important engineering achievement.
Can you build a tower?
How high can the blocks go?
What prevents cranes from tipping over when lifting loads?
Cranes are designed to lift a maximum load. Check to make sure that you do not exceed this!
The Science Bit
A crane is a machine used largely in engineering. It is used to raise, lower and position heavy loads. There are three main types of cranes used:
- Jib crane: The main parts are the power winch, rope and moveable arm (jib). The rope has a pulley block and hangs from the jib and is wound up and down by the winch.
- Overhead travelling crane: This consists of a fixed horizontal arm with a trolley carrying the pulley block that run along the arm.
- Tower crane: It has a long horizontal arm that is able to revolve, the arm carries a trolley.
Many cranes are situated on a revolving turn tablet help with manoeuvring the heavy loads.
Curriculum Links
Pushes and Pulls
- That there are many sorts of movement which can be described in many ways
- To observe and describe different ways of moving
- That pushing or pulling things can make objects start or stop moving
- To identify similarities and differences between the movement of different objects ( e.g. Robotic Arm)
- To make suggestions about how objects can be made to move and to find out whether they were right
- To recognise hazards and risks to themselves in moving objects
Forces and Movement
- That pushes and pulls can make things speed up or slow down or change direction
- To suggest questions about ways in which different objects move
- That pushes and pulls are examples of forces
Forces in Action
- That several forces may act on one object
