A cabin is mounted on a device frame, and hydraulic equipment is placed on a pedestal of the device frame. In this configuration, an attachment body of a front lower part of the cabin is disposed and attached onto an installation part on a front part of the pedestal; providing a front cover between the front part of the pedestal and the front lower part of the cabin for covering forward and outward of the hydraulic equipment; and providing a front plate on the front lower part of the cabin for supporting a lower edge of a front glass. A vertically intermediate portion of an inner surface of the front plate is fixed to the attachment body, and a lower part of the front plate is placed on an upper side of the cover to thereby cover forward and upward of the installation part of the pedestal.

A grip comprises a grip body forming a gripping control portion of a manually operable device to be held with the operator's palm and fingers. The grip body includes a ball-receiving surface coming into contact with the ball of the thumb, a palm-receiving surface coming into contact with a middle portion of the palm and the ball of the little finger, a finger-receiving surface coming into contact with the fingers, an open surface positioned between the tips of the fingers and the ball of the thumb for receiving the thumb when the grip body is held, and a switch mounted on a top portion of the grip body to be operable with the thumb. The grip body further comprises a thumb-guiding portion in the form of a shallow groove formed at an upper part of the ball-receiving surface of the grip body, the inside of the first joint of the thumb being placed along the thumb-guiding portion when the switch is operated, and a rising portion formed on at least either one of portions between the thumb-guiding surface and the open surface and between the thumb-guiding surface and the palm-receiving surface for applying resistance when the operator's hand advances into the switch.

A swiveling work machine includes a swivel deck, an engine and an operator's seat which are mounted on the swivel deck and a protector for the operator's seat mounted erect on the swivel deck. The swivel deck mounts, at a rear portion thereof, a support frame having four post portions disposed around the engine. Two rear post portions of the support frame have upper ends thereof connected via a rear beam member. The rear beam member includes an attaching portion for the operator's seat protector to which portion the protector is attached.

A work machine includes an attachment movable by an actuator, an operational member for operating the attachment through the actuator; and a controller operable to output an operation signal for operating the actuator in response to an operation of the operational member. The controller allows setting of a change amount in the operation signal corresponding to an operational amount of the operational member, independently for each operational direction of the actuator.

Work machine

A swiveling utility machine includes a swivel deck, an engine disposed at a rear portion of the swivel deck, a radiator disposed adjacent the engine, a driver's seat, a right implement controller disposed on the right side of the driver's seat and a left implement controller disposed on the left side of the driver's seat. A support frame is disposed at a rear portion of the swivel deck in such a manner as to create a rectangular space inside the swivel deck, the engine being mounted within the rectangular space. The driver' seat is disposed upwardly of the support frame. The right implement controller is secured to a right side of the support frame, and the left implement controller is attached to a left side of the support frame to be switchable in its posture between an operational posture and a retracted posture. An access step is disposed at a front portion of the support frame, and an access entrance is provided on a left side of the access step.
