Current through Register Vol. 24-14, July 15, 2024
3506-02 Mobile crane and hoisting services; Rigging
				contractors, N.O.C.
Applies to establishments engaged in mobile crane and hoisting
				services and rigging contractors not covered by another classification
				(N.O.C.). There are many types of cranes and derricks, both stationary and
				nonstationary. A mobile crane is a tire-mounted machine for hoisting and moving
				heavy objects by cables attached to a moveable boom. Rigging consists of a
				system of ropes, chains, cables, or tackle used for support. Generally, these
				types of establishments respond to and service customer requests such as
				righting an overturned tractor trailer, hoisting a large bell, or placement of
				a satellite dish on top of a building. In addition, mobile crane businesses
				often maintain a variety of nonmobile cranes and derricks such as those used
				for construction of tall buildings or structures. This classification includes
				transporting of a nonmobile crane or derrick to and from a customer site, but
				excludes the set up or erection, operating, and disassembling of the
				unit.
This classification excludes the construction or erection of
				permanent nonmobile cranes (such as those permanently mounted at a
				manufacturing plant or seaport to load cargo) which are to be reported
				separately in classification 0508; and the set up, erection, operating, and
				disassembling of cranes, hoisting devices or rigging in connection with work
				covered under a construction classification which are to be reported separately
				in the construction classification applicable for the work being
				performed.
Special note
:
This classification
				includes mobile crane and hoisting businesses when providing a service at a
				construction site such as lifting an air conditioning unit to a building top,
				and provided the crane operator is an employee of the crane and hoisting
				business.
3506-03 Concrete pump truck service
Applies to establishments engaged in concrete pump truck
				services, including the pump truck control box operator. A concrete pump truck
				is a large vehicle equipped with an adjustable boom spanning approximately 65'
				in length equipped with a flexible 4" hose running alongside the boom. This
				type of vehicle is different from a concrete ready mix truck which mixes the
				concrete in a rotating or revolving drum prior to arriving at the project site
				and discharges the mix with use of a metal chute. A concrete pump truck is
				designed to pump concrete into areas which are difficult for a concrete ready
				mix truck to reach such as a tall retaining wall, the foundation of a building
				or structure many feet below ground level, or into an area with limited access.
				Concrete is fed into the bed of the pump truck (usually by a ready mix concrete
				truck). The driver of the pump truck also operates the control box which
				adjusts the boom and amount of concrete mix to discharge. The control box
				operator receives instructions from a construction worker overseeing the
				concrete pour.
This classification excludes ready mix concrete dealers who
				deliver concrete who are to be reported separately in classification 3101 and
				all other concrete construction activities occurring at the project site which
				are to be reported separately in the classification applicable to the
				construction work being performed.
Special note
: This classification
				is limited to the concrete pump truck driver and operation of the control box.
				Construction workers at the project site, such as workers who are positioning
				and repositioning the end of the boom which discharges concrete, or workers who
				provide instructions with use of a headset to the control box operator, or
				workers who are spreading the concrete as it is poured, are to be reported
				separately in the classification applicable to the construction work being
				performed.
