Work in construction has tasks directly connected with manual transport. One of the body segments suffering greater demand in works with these characteristics is the lumbar spine segment. The aim of this study was to analyze the level of risk of lumbar construction workers in the shipment of materials. The sample was composed of 74 construction workers. Were used as a research tool: the NIOSH method for lumbar risk verification expressed by weight limit recommended (WPR) and the lifting Index (IL), Visual analogue scale (VAS) for the evaluation of pain intensity, the e-1 Corlett.0 for the mapping of the pain and Borg to the subjective perception of the intensity of physical exertion. The present study identified the weight limit (WP) of 8.707 for management activity of bags of cement for the load of 8.194 wheelbarrows used. These findings are 6 times under actual weights handled during the activities that revolve around 50 kg with the sacks and averaged 49.72 kg stands with mass. The dimensional settings found in the search are at high risk for ergonomic lumbar region, and measures of reconfiguration of workplaces and operation of auxiliary devices for lifting, transporting and unloading are fundamental, in addition to the need for reflection about the current logistical problems that induce producers to supply the cement sacks with 50 kg.
