432D and 442D Backhoe Loaders Caterpillar

Show/hide table

Failure to comply with the rated load can cause personal injury or attachment damage. Review the rated load of a particular attachment before performing any operation. Make adjustments to the rated load as necessary for non-standard configurations.

Note: Rated loads are based upon a standard machine with the following conditions:

• lubricants

• full fuel tank

• enclosed ROPS

• 80 kg (176 lb) operator

Rated loads will vary with different attachments. Consult your Caterpillar dealer regarding the rated load for specific attachments.

Note: Rated loads should be used as a guide. Attachments, uneven ground conditions, soft ground conditions, or poor ground conditions have effects on rated loads. The operator is responsible for being aware of these effects.

Special hazards (toxic gases, ground conditions, etc) require special precautions. The operator must determine whether special hazards exist in each application. The operator shall perform the appropriate steps in order to eliminate the hazard. The operator shall perform the appropriate steps in order to reduce the hazard.

Rated Load for Loader Buckets

For North American applications, the rated operating load is defined by the SAE standard "J818 May 1987" and by "ISO 5998 1986". For European applications, the rated operating load is defined by "EN 474-4 Feb. 1996". The rated operating load is defined as the lesser value of 50% of the static tipping capacity and the hydraulic lift capacity.

Dump Reach (A) and Dump Height (B)

Rated Load for Pallet Forks

For North American applications, the rated operating load is defined by the SAE standard "J1197 February 1991". The rated operating load is defined as the lesser value of 50% of the static tipping capacity or the hydraulic lift capacity. The intended operating range of the pallet forks starts from the fully racked back position. The range ends at the top face of the pallet forks at 20° below the horizontal at any given lift height.

For European applications, the rated operating load is defined by "EN 474-4 Feb. 1996". The rated operating load is defined as the lesser value of 80% of the static tipping capacity or the hydraulic lift capacity over firm and level ground. In rough terrain, the rated operating load is defined as the lesser value of 60% of the static tipping capacity or the hydraulic lift capacity. The intended operating range of the pallet forks starts from the fully racked back position. The range ends at the top face of the pallet forks at 20° below the horizontal at any given lift height.

Rated Load for Material Handling Arm

The rated operating load is defined by "EN 474-4 Feb. 1996". The rated operating load is defined as the lesser value of 50% of the static tipping capacity or the hydraulic lift capacity.

Remove the retainer pins from the arm in order to extend or retract the arm.

Replace the pins after the arm has been extended or retracted in order to lock the arm into position.

Lift the load close to the machine for best stability. Move the machine slowly in order to avoid excessive load swing.

Do not apply side loads on the hook and on the shackle. Check the condition of the hook, of the shackle and of any lifting chains. Replace the parts if any sign of unusual wear is indicated.

Rated Load for Backhoe Lifting and Object Handling

The rated load for the backhoe lifting applications is defined by "EN 474-4". Rated operating loads are given according to this standard. Additional rated operating loads are given with "SAE J31 March 1986" and "ISO 10567 1992" as a reference.

The rated load for the backhoe lifting applications is defined by "EN 474-4 Feb. 1996". The rated load for the backhoe lifting applications is defined as the lesser value of the following conditions at the specified lift point radius:

• 75% of the static tipping load

• the hydraulic lifting load

• 80% of the hydraulic holding load

The rated load for the backhoe lifting applications is defined by "SAE J31 March 1986" and "ISO 10567 1992" as a reference. The rated operating load for backhoe lifting applications is defined as the lesser value of the following conditions at the specified lift point radius:

• 75% of the static tipping load

• 87% of the hydraulic lifting load

Illustration 4	g00286077
Lift Point Radius (A)

The lift point radius is defined as the distance from the swing pivot center to the bucket hinge pin for the backhoe. The bucket hinge pin for the backhoe is level with the lower boom hinge pin at each lift point radius (A). Rated loads include the weight of the attachment. The rated operating loads are for the standard machine configuration.

Note: In the European countries, regulations require a load sensing indicator and a boom lowering control device if more than 1000 kg (2204.6 lb) is lifted with the backhoe during object handling applications. Even though the hydraulic lift capacity exceeds 1000 kg (2204.6 lb) for the object handling application, the rated object handling capacity for the backhoe is 1000 kg (2204.6 lb) in European countries due to these regulations.

432D Loader Buckets

The following tables provide the rated operating loads for the standard machine that is equipped with the given bucket. The corresponding dump clearance is given for each bucket at maximum lift height and at the full dump angle. The reach is given for each bucket at maximum lift height and at the full dump angle. Clearance is measured from the ground to the bucket edge in order to dump the load. The reach is measured from the front grill to the bucket edge.
