    摘要: Mining apparatus is disclosed in which a cutting wheel supporting a plurality of roller-cutters rotates about a horizontal axis and is supported on a slewing boom for cutting a tunnel with a flat floor and roof and elliptical walls as it slews across a mining face. The slewing boom is supported on a main beam assembly, the front end of which rests on powered crawler tracks and the rear end of which passes through a gripper assembly which may be clamped between the floor and roof of the tunnel, and against which the main beam assembly may be urged forward for engaging the roller-cutters with the mining face. A preload crawler is urged against the roof of the tunnel above the powered crawler tracks to locate the main beam assembly rigidly relative to the tunnel such that the roller-cutters may cut the rock in the mining face with minimal loss of cutting force due to vibration.

    摘要: A mobile mining machine for cutting a tunnel in rock has a wheel-like cutterhead assembly supported by a pitch boom assembly that causes movement of the cutterhead assembly in the vertical plane. A swing boom assembly supports the pitch boom assembly and is supported by the main frame of the mobile mining machine. In one embodiment the swing boom assembly has a pivot axis that is tilted from vertical and swings the cutterhead and the pitch boom during mining to cut a tunnel having a wide, flat floor. During mining, a gripper assembly having a floor gripper shoe and a roof gripper shoe brace the mobile mining machine in the tunnel. Thrust is provided by thrust cylinders located between the gripper shoes and the main beam. Extension of the thrust cylinders moves the cutterhead assembly, main beam, and rear portion of the mobile mining machine forward relative to the gripper assembly due to slidable engagement of the main beam and gripper assembly. During re-gripping, the gripper cylinders and thrust cylinders are retracted, causing forward movement of the gripper assembly with respect to the main beam and rear portion of the machine.

    摘要: A lockable package includes an outer sleeve defined by connected first and second panels, the sleeve having at least one open end. An inner container is slidable within the sleeve, and having a first portion joined to a second portion, wherein at least one of a height and a width of the first portion is less than a corresponding height and width of the second portion. A difference between one of the height and the width of the first portion and the corresponding height and width of the second portion defines a ridge. A locking assembly is provided at the at least one open end of the sleeve and is configured to releasably engage the ridge, wherein the inner container is removable through the open end of the sleeve by disengaging the locking assembly from the ridge.
