A portal pile driver, and a cast-in-place pile construction method are provided, relating to the technical field of pile foundation construction. The portal pile driver includes a portal frame, a pile frame platform, a moving assembly, and a lifting assembly. The portal frame is erected at one side of the pile frame platform, and a power head is installed on the portal frame. A loading zone is located at the pile frame platform, and a projection of a central shaft of the power head on the pile frame platform is located in an extension direction of the loading zone. The moving assembly is located at one side or each of both sides of the loading zone, and multiple drill pipes are horizontally distributed on the moving assembly, and each drill pipe is perpendicular to a plane where the portal frame is located.

In some implementations, the process may include securing, via an elevator, the tubular where the elevator is connected to a lifting mechanism by two or more spring bail cylinders in a retracted configuration. In addition, the process may include lifting the tubular via the elevator and converting the two or more spring bail cylinders to an extended configuration by the weight of the tubular. The process may include aligning the tubular with a member of the CRT at a top of the tubular, aligning the two or more spring bail cylinders around the CRT, and lowering the tubular to shift the weight of the tubular to a bottom of the tubular. Moreover, the process may include lowering the CRT and the two or more spring bail cylinders while simultaneously converting to the retracted configuration while maintaining alignment of the member of the CRT with the top of the tubular.

Aspects of the disclosure relate to counterbalance systems for catwalk systems, and related methods. A counterbalance system pulls a trough of a catwalk system while actuating the catwalk system. A catwalk system includes a chassis, a main arm pivotably coupled to the chassis, a trough pivotably coupled to the chassis and having one or more rollers, a V-door ramp pivotably coupled to the chassis, and a counterbalance system coupled to the trough at a coupling point. The counterbalance system includes a first sheave suspended from the V-door ramp, a second sheave suspended from the first sheave, and a counterbalance rope wound at least partially about the first sheave and the second sheave. A first end of the counterbalance rope is coupled to the trough at the coupling point.
