Which OSHA regulation primarily governs service truck crane operations in general industry?
Answer: 29 CFR 1926.1400
29 CFR 1926.1400 (Cranes and Derricks in Construction) is the primary OSHA standard covering crane operations including service truck cranes on construction sites.
Before a critical lift is performed, what document must be prepared?
Answer: A written critical lift plan
OSHA and ASME standards require a written critical lift plan for lifts exceeding 75% of the crane's rated capacity or other complex lift conditions.
A service truck crane operator notices the wire rope has a kink. What is the correct action?
Answer: Remove the rope from service immediately
A kinked wire rope is permanently damaged and must be removed from service because kinks severely reduce the rope's load-carrying capacity.
When communicating with a signal person, the operator should respond to signals from:
Answer: Only the designated signal person, except for a stop signal
The operator must respond only to the designated signal person, but must obey a stop signal from anyone regardless of who gives it.
What is the safe working load (SWL) of a 1/2-inch Grade 80 alloy chain sling in a basket hitch at a 60-degree horizontal angle?
Answer: Less than its vertical rated load
As the sling angle decreases from vertical, the effective load on each leg increases, reducing the SWL below the vertical rated capacity.
What information is typically found on a crane's load chart that an operator must verify before any lift?
Answer: Boom length, working radius, and boom angle
Load charts specify rated capacities based on boom length, working radius, and boom angle, all of which the operator must determine before lifting.
During a pick-and-carry operation with a service truck crane, what is the operator's primary responsibility?
Answer: Ensuring the load does not exceed the capacity listed for pick-and-carry on the load chart
Pick-and-carry capacities on load charts are significantly lower than stationary capacities, and the operator must never exceed these reduced ratings.
