Design of the Hoisting System for D-Zero Collision Hall Pit

PDF Version Also Available for Download.

Description

A hoisting rail system has been designed for lifting loads from the north sidewalk of the D0 collision hall into the collision hall pit. This engineering note documents the design. The hoisting system was conceived primarily to aid in getting heavy loads into the pit during short (less than a few days) accesses. The typical use for the hoist will be to lift a BLS power supply (120 lbs) and carrier (16 lbs) from a roll around cart on the sidewalk and onto a similar cart in the collision hall pit. The hoist system will alleviate the need for two ... continued below

Description

A hoisting rail system has been designed for lifting loads from the north sidewalk of the D0 collision hall into the collision hall pit. This engineering note documents the design. The hoisting system was conceived primarily to aid in getting heavy loads into the pit during short (less than a few days) accesses. The typical use for the hoist will be to lift a BLS power supply (120 lbs) and carrier (16 lbs) from a roll around cart on the sidewalk and onto a similar cart in the collision hall pit. The hoist system will alleviate the need for two persons to carry this heavy load up and down a narrow (24-inch) staircase. The hoisting system has a designed lift rating of 150 lbs. All members and components are well within a conservative safety factor when subjected to this loading at it's worst possible configuration, that is with it's boom cantilevered out 8 feet from the base rail. See the hoisting rail assembly sketch (in the hand calculations section) and the picture inserted below to get an orientation of the device. The hoisting system is designed using BLine 'unistrut' system components. The hoist consists of a 'base' rail that is fastened to either the northeast or northwest air handler platforms. This fixed base rail has (2) two sided trolley assemblies inserted into it's lower unistrut member. One assembly is locked in place on the base rail. Another is locked in place on the lower 'boom' rail. The trolley assemblies are free wheeling which allows boom movement in the north-south direction about 7 1/2 feet within the fixed base rail. An electric hoist hangs from the 'boom' rail on a single trolley. The hoisting system meets Fermilab Environment and Safety Manual chapter 5021 entitled 'Overhead cranes hoists and rigging'. Inclusive in that requirement is that it meets the applicable Fermilab 'work smart standards' of ANSI B30.11-1998 'Monorails and underhung cranes', and ANSI B30.16-1998 'Overhead hoists (underhung)'. The design criteria for the structural members per these standards is that static stresses shall not exceed 0.2 times the average ultimate material strength. The unistrut members are fabricated from hot rolled carbon steel. The B-Line catalog states that the minimum yield strength of the virgin material is 33,000 psi and the cold worked average yield stress is 42,000 psi. The ultimate strength of the material is not given in the catalog, but based on the description of the material and values listed in the Ryerson steel catalog, I will use a value 58,000 psi for the ultimate strength. A minimum safety factor of 5 must be achieved based on ultimate strength.
