overall lifting capacity is that of the lowest SWL

19
Q

lifting personnel competence

A

over 18 yrs old unless under direct supervision for training

adequately trained

20
Q

competent person

A

plans lift

21
Q

load handler

A

attaches / detaches load

22

authorised person

A

ensures load safely attached

23
Q

operator

A

operates crane

24
Q

responsible person

A

banksman

25
Q

assistants

A

relay communications

26
Q

LOLER reg 9

A 
thorough exam 
before first use,

6 mths if lift people, 
after exceptional circs
27
Q

LOLER Reg 10

A

written report as soon as poss after exam

28
Q

LOLER Reg 11

A

report to be kept for duration of its validity

29
Q

lifting equipment location

A

so low risk of hitting person or other structure / eqpmt
weight distribution on ground
ground surveys
power lines
no suspended loads over people / occupied buildings

30
Q

factors affecting stability

A

wind
slopes
ground conditions

31
Q

stability control measures

A 
correct installation
anchoring
firm ground
outriggers
avoid slopes
decrease load radius if uphill
32
Q

lift plan considerations

A 
load - weight, shape, centre of gravity, lift points, construction
eqpmt & accessories
proposed route of load
team required & competency
SSW & RA
environ - ground, weather
trial lift
derigging
33
Q

types of lifting accessories

A 
chain slings - single & multi leg
wire rope slings
fibre rope slings
round slings
eyebolts
shackles
hooks
block & tackle
34
Q

chain sling advantages

A

resist abrasion & corrosion

warning of excess loading = elongated links

35
Q

synthetic fibre slings

A

strong
durable
some resist chemicals
suspect to abrasion damage, sunlight damage

36
Q

eyebolts

A

dynamo = straight lift only
collar - straight & angle
collar & ring = angle only

37
Q

plate clamp

A

used for sheets of metal

not suitable for heavy loads

38
Q

case or drum sling

A

loads under 1 tonne
keep as close as poss to 60 degrees
check drum rim condition

39
Q

shackles

A

fix sling to load or eyebolt or to join slings

40
Q

lifting hooks

A

safety catch or ‘moused’ with wire, rope, strap
