MOBILE HAND-HELD SAWING MACHINE HAVING PRE-CUTTING ASSEMBLY AND GRIP
A mobile hand-held sawing machine having: a sawing assembly (11), which has a sawing tool holder (14) for a sawing tool (15) and a saw drive motor (12) for driving the sawing tool holder (14); and a guide device (17), which has a guide body (18) having a guide face (19), extending along a longitudinal axis (L), for guiding the hand-held sawing machine (10) in a working direction (AR) on a workpiece (W); the hand-held sawing machine (10) having a pre-cutting assembly (31), which is arranged on the guide device (17) in front of the sawing assembly (11) in relation to the working direction (AR) in a longitudinal position in relation to the longitudinal axis (L) and has a pre-cutter tool holder (34) for a pre-cutting tool (35) and a pre-cutter drive (32A) for driving the pre-cutter tool holder (34)
Cable cutter saw
A metal clad electrical cable saw cuts cable laying in a concave track. A cross-cut saw cuts entirely though the cable making the cable into two cables. Two slitting saws cut outer armor of the cable at two places approximately nine inches from the cross-cut to allow removing the severed outer armor. The two slitting saws cut through one or more overlapping rings of metal that form the outer armor which is of an extruded interlocking design, thereby allowing the outer armor to be removed exposing the electrical wires. Slitting blade guards protect an operator's hands while cutting the cable. The exposed electrical wires may be inserted into an electrical box for connection and the remaining outer armor typically “stops” inside an electrical connector. The connector secures the cable in accordance with applicable practice and code requirements.

DIVIDING GROOVE FORMING DEVICE, AND DIVIDING GROOVE FORMING METHOD
A dividing groove forming device includes: a first cutter including a plurality of first rotary blades; a second cutter including a plurality of second rotary blades; a first rotation drive unit for rotationally driving the first cutter; a second rotation drive unit for rotationally driving the second cutter; a cutter support unit; and a phase adjustment unit. The cutter support unit supports the first cutter and the second cutter such that the first and second cutters are radially opposed to each other so that rotation axes of the first and second cutters are parallel to each other. The phase adjustment unit adjusts a phase of at least one of the first cutter and the second cutter such that the first rotary blades and the second rotary blades are opposed to each other in an opposing area in which the first cutter and the second cutter are opposed to each other.
SAW GUIDES FOR GANG SAWS
A saw guide for attachment to a guide post of a saw guide arbor guide assembly includes a head and a body. The head is attached to the guide post. The head includes opposed first and second head surfaces, a collar wall, and a head sidewall. The collar wall extends between the first and second head surfaces, with the collar wall engaging with the guide post. The head sidewall extends between the first and second head surfaces and defines an outer perimeter of the head. The body is attached to the head and includes opposed first and second body surfaces and a body sidewall. The body sidewall extends between the first and second body surfaces and defines an outer perimeter of the body. The saw guide further includes a lattice structure extending within at least the body, with the lattice structure extending between the first and second body surfaces.
Systems and methods for cutting concrete piles
Systems and methods for cutting piles wherein, for example, a pile cutting device is attached to the end of an articulated arm of an excavator, the pile cutting device having a set of grasping arms that hold the pile and a set of saw blades that are linearly advanced to cut the pile in a single stroke. The saw blades are offset so that the cutting paths of the blades overlap. The saw blades may be positioned at the ends of telescoping arms that are coupled to a linearly movable frame. A single hydraulic unit moves the frame along a central rail. The frame is coupled to one or more cables and pulleys so that the travel of the telescopic arms is twice that of the frame.
TWO-PART PIVOTABLE MOUNTING BLOCK FOR INDUSTRIAL EQUIPMENT
A two-part pivotable block component for mounting interposed a piece of industrial equipment and its mounting base. The two-part pivotable block component comprises an upper first part that is engageable with the base of the industrial equipment, and a lower second part that is engageable with a mount for the industrial equipment. The first part of the pivotable block component has an inclined surface in a first plane for pivotably engaging an inclined surface provided therefore on the second part of the pivotable block component. The inclined surface of the second part of the pivotable block component is in a second plane. The two-part pivotable block component is suitable for use with industrial equipment exemplified by electrical motors, hydraulic-driven motors, pressure-driven motors, and pumps. The two-part pivotable block component is also suitable for aligning arbors cooperating with industrial equipment.

Pipe cutting tool
An example pipe cutting tool includes a plurality of actuators and a plurality of cutters. Each of the plurality of cutters is connected to at least one separate actuator of the plurality of actuators. The at least one separate actuator is configured to move the cutter between a pre-deployed and deployed position. The deployed position is beyond the pre-deployed position. The plurality of cutters may include a first and second cutter, with the at least one separate actuator connected to the second cutter moving based, at least in part, on one or more cutting conditions. An example method of cutting a pipe includes extending a first cutter to contact the pipe, cutting at least a portion of the pipe using the first cutter, detecting a cutting condition, extending a second cutter based, at least in part, on the cutting condition, and resuming the cutting using the second cutter.
