Heavy hammer type lifting height limiter and heavy hammer thereof

The invention discloses a heavy hammer type lifting height limiter and a heavy hammer thereof. The heavy hammer type lifting height limiter comprises a left side pipe, a right side pipe, fastening bolts, a fastening platform, bolt holes and a lifting lug. Cross sections of the left side pipe and the right side pipe are arc-shaped, the cross section of a lifting steel wire rope is circular, a contact surface between the two is contact between arc-shaped surfaces, the contact area is significantly smaller than the original contact area between a steel ring and the lifting steel wire rope, and the abrasion loss between the heavy hammer and the lifting steel wire rope is reduced. Continuous openings distributed along the whole length direction are formed in the pipe wall of each of the left side pipe and the right side pipe, so that the heavy hammer is pulled away from the lifting steel wire rope after the fastening bolts are dismounted; the operation of unfastening the whole lifting steel wire rope in the prior art is thoroughly avoided, so that the parts of the heavy hammer type limiter are convenient to maintain and replace; the time and the labor are reduced. The heavy hammer type lifting height limiter is simple in structure and low in manufacturing cost, can use locally available materials, can be self-manufactured, and is relatively low in cost.
