Instruments in the laboratory
- Lifting and carrying crane
It is a mechanical crane that can move horizontally with a lifting capacity of 2 tons. It is used for lifting and carrying heavy objects. It is generally used in all experiments consisting of heavy test elements.
How to use:
- The crane is brought over the object to be lifted.
- Check the stability of the lifting eye of the heavy object.
- The hook of the crane is inserted into the lifting eye on the heavy object.
- Make sure that the hook is inserted correctly and will not come off.
- If available, people in the surrounding area are removed and security measures are reviewed.
- The load is lifted in a controlled manner.
- After the object is lowered to the right place, its stability is ensured and the crane is separated from the object.
Instructor Faruk Ogun and Hüseyin Kalkan are responsible for the crane.
Security precautions:
It cannot be used without wearing a helmet, gloves, and steel-toed shoes.
- Sample Test Press
It is a hydraulic press with a pressure capacity of 200 tons. It is used to determine concrete cylinder and cube strengths. It is used in all tests where concrete strength is required.
How to use:
- The engine button and digital indicator of the press are turned on and it is waited for at least 10 minutes to warm up.
- The sample is put into the press.
- Steel fillers are used if necessary for excess spaces.
- The maximum load memory is unlocked before starting the load.
- Loading is done slowly.
- After the element starts to load, the safety cover is closed.
- The maximum load is recorded after the element breaks.
- The maximum load memory lock is turned off and the element is ejected.
- If another element is to be broken, it is repeated after the 2nd item.
- When the job is finished, the press motor and digital display are turned off. The press is cleaned.
Instructor Faruk Ogun and Hüseyin Kalkan are responsible for the Sample Test Press.
Security precautions:
It cannot be used without wearing a helmet, gloves, glasses and steel-toed shoes.
- Hydraulic jacks
Hydraulic jacks have 20-150 and 10-75 tons of pressure and pulling capacity respectively. They are used in the application of tensile and compressive loads.
How to use:
- Before connecting the pump to the jack, the hose end and the place where it will enter are cleaned.
- The pump is connected to the jack.
- The jack piston is protected against possible debris during load application.
- Load is applied by a hydraulic jack.
- At the end of the test, the piston, jack and pump are cleaned.
Instructor Faruk Ogun and Hüseyin Kalkan are responsible for the Hydraulic jacks.
Security precautions:
It cannot be used without wearing a helmet, gloves, and steel-toed shoes.
- Electronic Displacement Meters (LVDT)
LVDTs are electronic displacement meters with an amplitude of 25-200 mm. They are used in all experiments that require deformation measurements.
How to use:
- The LVDT is carefully removed and connected to the measurement location, then its cable is attached.
- Necessary precautions are taken against stepping on the cables and weight drops.
- Safety is ensured against possible explosions and sudden collapses during the test.
- The instrument is calibrated and at the end of the experiment, it is carefully disassembled and put into its box.
