Crane Operation Controls

◆ According to TADANO’s system, lever arrangement changes as follows:

1. Main hoist control lever

→ Auxiliary hoist control lever

2. Boom elevating control lever

→ Main hoist control lever

9. Auxiliary hoist control lever

→ Boom elevating control lever

This section provides the meaning of some important terms used in this manual.

Load Radius, Lifting Height

"Load radius" refers to the horizontal distance between the crane's center of rotation and the vertical center of the lifted load.

A "lifting height" is defined for each load radius and refers to the vertical distance between the ground and the bottom of the hook block raised to its uppermost position.

Jib Length, Jib Offset Angle

"Jib length" refers to the center-to-center distance as illustrated in the figure below.

"Jib offset angle" refers to the angle formed by the centerline of an extended jib and the centerline of the boom.

Maximum Lifting Height

"Maximum lifting height" refers to the maximum lifting height allowed.

Boom Length, Boom Angle

"Boom length" refers to the distance from the pivot pin at the foot of the boom to the center axle of the sheave(s) at the boom head.

"Boom angle" refers to the angle formed by the boom's centerline and the horizontal.

Rated Lifting Capacity

"Rated lifting capacity" refers to the maximum allowable load for a particular boom length and working radius. The rated lifting capacity includes the weight of the hook block, rigging and load handling devices.

The weight of individual hook blocks are indicated in the "INFORMATION AND DATA" section at the end of this manual.

Without Load

The phrase "without load" is used to indicate that no load is being lifted on the hook block.

Stability Section, Strength Section

"Stability section" refers to the section of the rated lifting capacity table in which the major factor for determining lifting capacity is the stability of the crane.

"Strength section" refers to the section of the rated lifting capacity table in which the major factor for determining lifting capacity is the structural strength of the crane. In the rated lifting capacity table, the values below the blue line are based on the stability of the crane. The values above the blue line are based on the structural competence of the crane for on-outrigger operation, or of the tires for on-rubber operation.

Over-front

"Over-front" refers to the forward working area of the carrier for which lifting capacities have been rated and listed in the rated lifting capacity table.

Over-front Capacity, 360-degree Capacity

Outrigger Extension Width

“Outrigger extension width” refers to the horizontal distance between the right and left outrigger floats when outriggers are extended.

(1)Outrigger maximum extension width (L1)

This refers to maximally extended outrigger extension width.

(2)Outrigger middle extension width (L2)

This refers to designatedly-middle-extended outrigger extension width.

(3)Outrigger minimum extension width (L3)

This refers to designatedly-minimum-extended outrigger extension width.

"Over-front capacity" refers to the rated lifting capacity that can be lifted in the over-front area.

"360-degree capacity" refers to the lifting capacities that remain the same regardless of the area in which the load is lifted.

Maximum Extension Capacity, Middle Extension Capacity, Minimum Extension Capacity

(1)Maximum extension capacity

Lifting capacity when outriggers are maximally extended.

(2)Middle extension capacity

Lifting capacity when outriggers are extended to middle.

(3)Minimum extension capacity

Lifting capacity when outriggers are minimally extended.

On-outrigger Operation

"On-outrigger operation" refers to an operation performed with a crane that is supported on outriggers.

On-rubber Operation

"On-rubber operation" refers to an operation performed with a crane that is supported on the tires, and not on the outriggers.

Traveling with Load on Hook

"Traveling with load on hook" refers to traveling with a suspended load. No crane operations are being performed during this activity.

Raising Load Just Clear of Ground

“Raising load just clear of the ground” refers to clearing the load from the ground by hoisting up.
