( 1 ) The weight includes a full fuel tank, a 75 kg (165.3 lb) operator, an enclosed operator station, and a standard bucket. If additional attachments have been installed on your machine, the weight of your machine may vary.Intended Use
The R2900G Load Haul Dump is a self propelled wheeled machine. The machine is primarily intended for use in underground applications.The R2900G Load Haul Dump has a front mounted bucket or work tool. Work tools are used for digging, loading, lifting, and carrying material such as fractured rock or crushed rock.Application and Configuration Restrictions
The maximum approved Gross Machine Operating Weight of the R2900G Load Haul Dump (including payload) is 72346 kg (159495 lb).The operator station is ROPS certified to ISO 3471:1994 and up to 58000 kg (127868 lb) machine mass only (no payload). Use only in a non-explosive gas environment. Avoid conditions that can lead to tipping the machine. The machine can tip when you work on hills, banks and on upward and side slopes. The machine can tip when you cross ditches, ridges, or other unexpected obstacles. Avoid operating the machine across a slope as there are many factors that can adversely affect stability and for that reason Caterpillar does not provide data for such operations.ReferenceRefer to Operation and Maintenance Manual, "Slope Operation" for more information.

R2900G Operating Restrictions    Grade    
Maximum Working Grade (1)     20%    
Parking Brake Holding Capability (2)     25%    
Maximum Side Grade for Dumping (3)     0%    
( 1 ) There are many variables to consider when operating on a grade. For example: grades that can be partially side sloped and can be soft, hard, wet, dry, loose, firm, graded, not graded, and frozen. Such variability will affect traction and rolling resistance and the individual circumstances must be considered before operating on any grade
( 2 ) The listed restriction assumes that the brake components are within working specifications, the machine mass is at maximum allowable, a graded ground surface, and a dry, firm underfoot. The machine operator is responsible for evaluating the condition of the machine, the environment, and using appropriate judgment to maintain control of the machine.
( 3 ) Dumping on a grade when the machine is articulated is not recommended. Dumping on a side grade is not recommended. Machines are designed to dump on level ground with some variation in underfoot surface conditions. The center of
