Pennsylvania Code › Title 7 - AGRICULTURE › Part V-D - Amusement Rides and Amusement Attractions › Chapter 139a - SAFETY STANDARDS FOR BUNGEE JUMPING › OPERATIONS › Section 139a.26 - Cranes

Current through Register Vol. 54, No. 28, July 13, 2024
(a) A crane shall
				  have certification of inspection by a testing firm accredited by the United
				  States Department of Labor. This certification shall be done at each location
				  prior to operation and shall be redone on at least an annual basis.
				  Recertification is also required whenever the crane is used for material
				  lifting-as opposed to bungee jumping-purposes. Certification shall be complete
				  prior to the inspection required by §
										139.7 (relating to
				  inspection).
(b) A crane used to
				  elevate mobile platforms for bungee jumping shall be equipped with boom angle
				  indicators, boom extension indicators and drum rotation indicators.
(c) The crane shall be equipped with a swing
				  lock mechanism to limit the rotation of the crane to the operational limits of
				  the bungee jump.
(d) The crane
				  shall be equipped with operational stabilizer bars or cables which stabilize
				  the mobile platform during the jump to ensure a consistent jump
				  space.
(e) A positive acting device
				  shall be used which prevents contact between the load block or overhaul ball
				  and the boom tip (anti-two-blocking device), or a system shall be used which
				  deactivates the hoisting action before damage occurs in the event of a
				  two-blocking situation (two block damage prevent feature).
(f) The total weight of the loaded platform,
				  the related rigging and the dynamic load may not exceed 50% of the rated
				  capacity for the radius and configuration of the crane-for example, a rated
				  load of 3,000 pounds becomes 1,500 pounds.
(g) A crane shall be level, on firm footing
				  and the outriggers fully extended and blocked in an acceptable
				  manner.
(h) The load line hoist
				  drum shall have a system or device on the power train, other than the load
				  hoist brake, which regulates the lowering rate of speed of the hoist
				  mechanism-controlled load lowering. Free fall is prohibited.
(i) Live boom equipment may not be
				  used.
(j) Load lines shall be
				  capable of supporting, without failure, at least seven times the maximum
				  intended load, except that if rotation resistant rope is used, the lines shall
				  be capable of supporting without failure, at least ten times the maximum
				  intended load.
(k) Load and boom
				  hoist drum brakes, swing brakes and locking devices such as pawls or dogs shall
				  be engaged when the occupied personnel platform is in a stationary working
				  position.
(l) A daily log book for
				  operator inspections and repairs shall be kept on site.
(m) The main boom is to be fully extended at
				  all times.
(n) A crane that uses a
				  jib with cable supported back stays shall have positive stops to prevent the
				  jib from moving more than 5° above the straight line of the jib and boom or
				  detaching from its mount point. The use of cable type belly slings does not
				  constitute compliance with this subsection.
(o) The lifting and supporting shall be made
				  under controlled conditions and under the direction of an appointed signal
				  person.
(p) The crane shall be
				  operated by a person who has been adequately trained in its operation in
				  accordance with the training recommendations of the crane manufacturer. In the
				  absence of these recommendations, the Department may require other documentary
				  or demonstrative evidence, or both, of a person's proficiency in operating the
				  crane.
(q) Communications shall be
				  maintained between the crane operator, the signal person and the person being
				  lifted.
(r) The crane operator
				  shall remain at the controls when the mobile platform is occupied.
(s) Movement of the mobile platform shall be
				  done in a slow, controlled, continuous manner with no sudden movements of the
				  crane or mobile platform.
(t) A
				  crane may not travel while a person is on a mobile platform attached to that
				  crane.
