5. Travels on public highways at normal road speed, meets road traffic regulations
BASE-Truck Mounted Crane

6. Designed for level ground, hard. Packed or within factories. Short chassis.
Possibly fitted with outriggers/stabilisers.Travel with suspended loads.One
cab - driven and operated, limited vision
BASE-Yard Crane/Low Headroom

7. BASE-Terrain Rough
Off road, large balloon tyres,slow moving,highly manoeuvrable

8. BASE-All Terrain Crane
Hybrid - truck and rough terrain, fast on public highways, most models all axle
drive and steer, therefore highly manoeuvrable, traverses uneven ground

9. Used on sites with poor ground bearing pressure, which often proves to be
unsuitable
for wheeled cranes. Crane is transported to site in parts. Erection and dismantling
May require an auxiliary crane. Requires large area for erection especially for long
Boom configurations and transportation.
BASE- Crawler Crane

Free On Wheels:
-On rubber, 360 degree, static only
-Pinned to rear of crane
-Shortest boom (Restricted jib length)
-Creep speed
-Firm level ground
-Axle locks
-Tyre pressures

55. Lateral efforts .
Verticalization & dragging of loads
Sharp turns
Dragging loads

56. Increase in the radius of load

57. Enough distance
Overload or impact---Impact on the boom

58. Out-of service 47-52 km/h
Extremaly careful 30-40 km/h (8,33-11,11 m/s)
Manufacturer’s recomendations
WIND

59. ELECTRICITY

60. No Lifting equipment should be closer than:
 15m to overhead power lines suspended from steel towers
 9m to overhead lines supported on wooden poles
ELECTRICITY

61. WORK WITH MORE THAN ONE CRANE:
QCRANE 1 = (A2 x Q) / L = (2 m x 100 TN )/4 m = 50 TN
QCRANE 2 = (A1 x Q )/L = (2 m x 100 TN )/4 m = 50 TN
L= distance between crane-hook-cg/ between support
CRANE 2 SUPPORT BEAM
SO NOW IT IS BETWEEN CRANE 1 AND BEAN SUPPORT
QCRANE1 = (A2 x Q) / L = (8 m x 100 TN )/8 m = 80 TN
QSUPPORT = (A1 x Q )/L = (2 m x 100 TN )/10 m = 20 TN

64. • Points to be considered:
– weights, dimensions and characteristics of loads
– operational speeds, radii, heights of lift and areas of
movement
– number, frequency and types of lifting operations
– length of time on site
– site, ground and environmental or site and building
restrictions
– space available for crane access, erection, travelling
operations and dismantling
– special requirements or limitations
– costs - not at expense of safety
