Big Stan is a vehicle-mounted drill rig built in 1986 by Anderson Drilling. The rig has been used on a number of construction projects in which conventional, smaller drilling rigs were unable to be used, particularly when projects call for drilling into hard soil. Notably, Big Stan was used in the construction of the First National Bank Tower in Omaha, the Benicia-Martinez bridge near San Francis. HistoryBig Stan was built in 1986 by Anderson Drilling (Now part of ) in . The machine. .
Big Stan was designed as a v that is normally mounted on a 40 feet (12 m) long, 5-axle truck, but is also compatible with a specially designed -style carrier. When made fully operati.

Drill pipe elevators for USC with taper shoulder and square shoulder weld-on tool joints shall have bore dimensions as specified in Table 1. Notes on Table 1: Oilfield elevators with identical bores are the same. 1. * Not Manufactured. 2. ** Obsolescent connection. 1. 1 Dimension DTE from API Spec. 7, Table 4.2 2. 2. .
A very close fit of the hinge pin and pawl significantly affects the correct functioning of an elevator – especially the center-latch elevator. If there is play in the hinge, the elevator tends to. .
In addition to the side-door elevator, single-joint and slip-type casings are used in running casing. We use a single-joint elevator (Figure 7) to. .
Since both care and inspection procedures depend primarily upon the amount of service the equipment has had, it is challenging to project. .
The following checks apply to all types of elevators. For a quick reference to critical points of the drill pipe elevators, see Figure 29. 1. Is the oilfield elevator size correct? 2. Are the dies of slip-type elevators sharp? 3. Are the hinge pin or holes worn? 4. Are.
