The thickness of the wire rope used in a 15-ton E.O.T crane depends on various factors.
The thickness of the wire rope is determined by the load capacity and safety factors.
The type of wire rope, such as 6x19 or 6x37, also affects the thickness.
The diameter of the wire rope can range from 10mm to 32mm or more.
Consulting the crane manufacturer's specifications or engineering standards is necessary to determine the exact
The company XYZ uses mobile cranes and blackhole loaders for mechanical maintenance. The capacity of the mobile crane varies depending on the model.
The company XYZ utilizes mobile cranes and blackhole loaders for their mechanical maintenance operations.

The name used for two travelling EOT cranes not touching each other during working time is 'tandem operation'.
Tandem operation is a technique used in crane operations where two cranes work together in synchronization.
The cranes are controlled by a single operator and operate in close proximity without touching each other.
Tandem operation allows for increased lifting capacity and flexibility in handling heavy loads.

There are several types of earthing including plate earthing, pipe earthing, rod earthing, strip earthing, and water pipe earthing.
Plate earthing involves burying a plate made of copper or galvanized iron in the ground.
Pipe earthing uses a pipe made of galvanized iron to provide a low resistance path to the ground.
Rod earthing involves driving a metal rod into the ground to provide a connection for earthing.
Strip earth...

Yes, ACB settings refer to the settings of Air Circuit Breakers used in electrical systems.
ACB settings include parameters such as overload protection, short circuit protection, and ground fault protection.
These settings can be adjusted based on the specific requirements of the electrical system.
For example, the trip unit of an ACB can be set to trip at a certain current level to protect the system from overloads.
Power factor is a measure of how effectively electrical power is being used in a system.
Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.
It indicates how efficiently power is being converted into useful work.
A power factor of 1 indicates all power is being used effectively, while a lower power factor means some power is being wasted.
Power factor correction can be used to impr
I will first check the cause of the trip, reset the ACB, and then investigate further if needed.
Check the cause of the trip - look for any overload, short circuit, or earth fault
Reset the ACB by switching it off and then on again
Investigate further if needed - check for any faulty components or wiring
VRF stands for Variable Refrigerant Flow and is a type of HVAC system that uses refrigerant as the cooling and heating medium. AHU stands for Air Handling Unit and is a device used to condition and circulate air as part of an HVAC system.
VRF systems use refrigerant to directly cool or heat the space, while AHUs use chilled or heated water to condition the air before distributing it.
VRF systems are more energy efficient...

HT motor rating is the maximum power it can handle and FLC is the current it draws at full load.
HT motor rating is expressed in kilowatts (kW) or megawatts (MW).
FLC of HT motor is the full load current it draws at rated voltage and frequency.
FLC is expressed in amperes (A) and varies depending on the motor's power rating and efficiency.
For example, a 1 MW HT motor may have a FLC of 1000 A at 11 kV.
The rating and FLC of...
