Skid steer loader

A skid steer loader, comprising:

• a chassis frame, assembled with a walking system to form a movable chassis of the skid steer loader, wherein a power system of the skid steer loader is assembled to a tail portion of the chassis frame;
• a cab, arranged on a front portion of the chassis frame in an overturning manner, wherein a first side of the bottom of the cab is fixedly hinged to the chassis frame, a second side of the bottom of the cab is supported and connected to the chassis frame at a position other than a hinged position by a telescopic support rod, and the cab is horizontally placed on the chassis frame when the telescopic support rod is in a retracted state and overturns forward towards a front of the skid steer loader when the telescopic support rod is in an extended state, to expand an inspection space between the cab and the power system;
• and
• a main beam and a bucket, wherein a tail end of the main beam is movably hinged to the tail portion of the chassis frame by a four-bar linkage mechanism, the bucket is assembled to a front end of the main beam, a loading and unloading oil cylinder for driving loading and unloading is assembled between the bucket and the main beam, and a lifting oil cylinder for driving the main beam to swing up and down to lift and lower the bucket is assembled between the main beam and the chassis frame,
• wherein a main beam safety rod is arranged on the main beam, one end of the main beam safety rod is hinged to a hinge point of the main beam and the lifting oil cylinder, and a safety rod fixing plate for detachably fixing the main beam safety rod is arranged at a position close to the front end of the main beam;
• and the main beam safety rod is provided with a through groove for accommodating a piston rod of the lifting oil cylinder, a length of the through groove corresponds to an extending length of the piston rod of the lifting oil cylinder, and when the main beam controls the bucket to be in a lifted state, the main beam safety rod swings toward a back of the skid steer loader to cover the piston rod of the lifting oil cylinder, and an end portion of the main beam safety rod abuts against an end portion of a cylinder barrel of the lifting oil cylinder, to prevent the piston rod of the lifting oil cylinder from retracting into the cylinder barrel.
