Abstract
A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.
Claims19
A swivel working machine comprising:
- a swivel base;
- a prime mover provided on the swivel base;
- a working device provided on the swivel base;
- and
- a support mechanism to support a fuel cylinder in a rotatable manner around a pivot shaft, the fuel cylinder containing fuel for the prime mover, wherein
- the support mechanism includes
- a support rotating body to support the fuel cylinder and rotate around the pivot shaft,
- a rotational-position defining mechanism including a pin to define a rotational position of the support rotating body around the pivot shaft, and
- an adjustment mechanism to adjust a position of the pivot shaft relative to the pin.
A swivel working machine comprising:
- a swivel base;
- a prime mover provided on the swivel base;
- a working device provided on the swivel base;
- and
- a support mechanism including a support rotating body to support a fuel cylinder in a rotatable manner in an up-down direction, the fuel cylinder containing fuel for the prime mover, wherein
- the support mechanism includes
- a bias member to receive a weight of the fuel cylinder and apply a resilient repulsive force in a direction such as to inhibit downward rotation of the support rotating body, and
- an assist mechanism to increase the resilient repulsive force acting on the support rotating body.
