Method of marking cranes and hoists KPK

MŽJZE3,2/14
abcdef g

a/ type of crane

M - overhead travelling crane

P - gantry crane

if the 2nd letter in the name is Z, the letter P means monorail crane

PZ - monorail crane

S - pillar cranes

K - wall slewing cranes

b/ type of lifting device

Ž - crane

ŽT - crane with permanent spreader beam

Z - monorail crane

ZT - monorail crane with permanent spreader beam

ŽP - under running overhead travelling crane

c/ number of crane bridge girders

J - single girder

D - double girder

Note: for pillar and wall slewing cranes, the number of girders is not specified.

d/ type of crane main beam

Z - welded, box construction

K - side running hoist

G - crane from Unit-Built System KPK KB

Note: if nothing is specified, the bridge or arm is made of rolled profile

e/ crane drive type

E - electric

R - manually

Note: for pillar and wall slewing cranes, the letter O means that it is rotatable.

f/ crane load capacity in tons

e.g.. 3.2 is load capacity 3200 kg

g/ span or reach of the crane arm in m

The number indicates the span for bridge - type cranes, or max. reach of the crane arm for pillar and wall slewing cranes in m.

Example of marking a doublegirder overhead crane, welded main beams, with an electric drive, with a load capacity 5000 kg and span of 10 m.

A

  • Auxiliary Hoist – A supplementary lifting device used to assist or serve as an alternative to the main hoist for vertical movements, can provide different speeds and load capacities than main hoist.

B

  • Beam - The main horizontal structure in a crane.
  • Brake - An essential safety component, controlling and stopping crane mechanisms.
  • Bridge – The crab or crabs are carried on this part of the crane construction.
  • Bridge Travel or Long travel - Movement of the crane parallel to the runway.

C

  • Cab - Crane cab serves as the safe and comfortable operator's station.
  • Capacity - lifting capacity represents the maximum safe weight or load it can handle, maximum load of crane.
  • Center of Gravity - in a crane refers to the point where the entire weight of the crane and its load is concentrated.
  • Clearance – The space or distance from the crane to the point of the nearest obstruction.
  • Controller – Regulates the power supply to the corresponding motor.
  • Corrosion Resistant – Prevents corrosion of parts of the crane construction.
  • Counterweight – A counterweight is an amount of weight that balances a crane and its load. Counterweights are typically added to the opposite side of the crane to the load.
  • Crab - see Trolley.
  • Crane – Equipped with cables and pulleys and based upon the application of fundamental mechanical principles. Crane can lift and lower loads.

D

  • Dead Load - The weight of the crane itself or other components, which remains constant during crane working.
  • Dead end - end of a wire rope or chain opposite to where the load is applied.
  • Design Life -The intended duration for which a crane is designed to operate safely under normal usage conditions.
  • Drum – A cylindrical component in a crane's hoisting mechanism, responsible for winding and unwinding hoisting wire ropes or cables during lifting.

E

  • Electric Overhead Travelling Crane – A crane that travels overhead, often mounted on a girder, powered by electricity. Abbreviation - EOTC.

F

  • Footwalk - A safe and accessible walkway (platform) for crane operators and maintenance personnel.

G

  • Gantry Crane – Crane attached to a gantry with crab.

H

  • Height Of Lift – Hook path - Measurement of the distance from the floor to the load level. Abbreviation - HOL
  • Hoist – The part of the crane that lifts or lowers the load.

J

  • Jib – The horizontal part of construction of the crane (arm) that supports the hoist.

L

  • Lifting Capacity – The capacity of lift of crane - weight terms.
  • Load – The load is what the crane lifts.

M

  • Main Hoist – Hoist that can lift the main load.
  • Max Lifting Capacity – The maximum capacity of lift of crane - weight terms.

N

  • Normal Working Load ( Safe Working Load )– The load a crane can safely handle without damaging the lifting mechanism or crane structure. Abbreviation - NWL

O

  • Overhead Travelling Crane – A crane that travels overhead on craneway.

P

  • Power supply trolley on bridge – Providing power to the trolley, supply trolley are along the bridge of the crane.
  • Power supply trolley on Runway – Providing power to the crane, supply trolley are along the runway.
  • Pulley Block (sheave) – a wheel with a groove for a wire rope to pass through.

R

  • Rail – Part mounted or welding on beam of craneway or bridge of crane.
  • Runway – Cranes travel on a runway.

S

  • Safe Working Load – The load a crane can safely handle without damaging the lifting mechanism or crane structure. Abbreviation - SWL

T

  • Trolley – allows movement for the hoist.

W

  • Wire rope - lifting element.
  • Working Load Limit – Maximum working load for the crane . Abbreviation -  WLL
  • Working Radius – The radius over the area the crane will carry out its work.
