Heavy Equipment
Safety
Many types of mobile construction heavy equipment are being used in a
construction site doing a wide variety of work. Most of these machines
operate within close proximity to persons on foot. With this, many people
are exposed to hazards associated with this equipment.
In short, you have a congested construction site with personnel on foot, and
mobile machines working in the same area at the same time

5 Basic Guidelines on Heavy Equipment Operation
When using heavy equipment, there are 5 basic guidelines that the operators
must always follow to ensure safety:
1. Know how to properly operate the equipment you are using
2. Do not use heavy machinery when you are drowsy, intoxicated, or taking
prescription medication that may affect your performance
3. Use only equipment that is appropriate for the work to be done
4. Inspect your equipment to ensure that it is in good working condition
before beginning a job. In addition, ensure that regular inspections and
maintenance are conducted as appropriate
5. Do not stress or overload your equipment.
Materials Handling refers to any method for moving materials.
• Manual Lifting (by people)
• Mechanical Lifting (by people using machines/equipment)
• National Safety Council (NSC) study
shows that 20% – 25% of all
occupational injuries result from
material handling activities.
• International Labor Organization
(ILO) statistics shows that 20% to
50% of work accidents are
attributed to materials handling.

• Proper rigging operation
• Proper assembly & dismantling procedure
5 Main Components of a Crane with its Functions
1. Hook
2. Hoist
3. Wheels and Tracks
4. Outriggers
5. Boom
Crane operators must understand and check the weight or load charts
applicable to the crane to be used. Weights should be marked on loads,
contained on manifests or shown on drawings.
Crane load charts may vary according to a few different factors, but they
generally contain information related to the crane’s lift capacity, lift range,
boom angle, movement, and deduction.
Crane Load Charts allow you to calculate a crane's maximum capacity as
different boom lengths and angles.
1. Tower Crane Load Chart
- based on radius
2. Mobile Crane
- boom length
- boom angle indicator

• At least 2 wire of rope shall remain in the drum when the hook is placed at
the lowest portion
A. Pre-Operation
• Barricade areas in which personnel could be trapped or crushed.
• Mark the location of all underground utility services
• Check engines, controls, brakes, safety devices for normal operation.
- overhoist safety device
- trolley limit switches
B. During Operation
Rule #1 Do not carry or use crane beyond the rated load
Rule #2 Never move load over people.
Rule #3 Never allow personnel to ride on a load.
Rule #4 Center the crane over the load before starting to hoist.
- Keep hoisting ropes vertical
- No side pull
Rule #5 Lift, move & lower loads smoothly.
Rule #6 Crane operators should not use limit switches to stop the hoist
under normal operating conditions.
Rule #7 Do not leave suspended load unattended.
B. During Operation
Rule #8 Keep hook block more than 2m above the floor when not in use.
Rule #9 Use tagline to stabilize and control loads.
Rule # 10 Respond to signals from designated signalman only.
Precautions shall be taken when erecting and dismantling a crane to ensure
that the stability of the crane is maintained. In particular, the following
procedures shall be followed where applicable:
• Only parts and components meeting the manufacturer’s specification shall
be used.
• Jointing pins shall be assembled so that they can be removed by a person
standing on the outside of the assembly.
• All outrigger jacks shall be fitted with foot plates according to
manufacturer’s instructions.
• All outrigger jacks shall be fitted and adjusted in accordance with the
operating instructions.
• The correct amount of counterweight shall be fitted on the crane and at
the appropriate location before the boom or jib is raised.
• When the operating length of boom or jib is reduced, the specified
counterweight shall be removed to ensure that the backward stability of
the crane is not adversely affected.
• Appropriate precautions shall be taken before a long boom is lowered to
the ground level.
• To maintain the best margin of stability when a long boom is raised or
lowered to the ground level, the hook blocks shall be lowered and rested
on the ground before the Boom or jib is lowered.
• Where timbers are used under outrigger footplates, they shall be arranged
so that successive layers are laid at 90o to each other (pig sty fashion) so
that the top layer is in line with the outrigger arm.
Rigging is the process where a load is prepared for lifting using a lifting
machine. The main part of this process is the tying up of the load with sling
and/or other connecting devices so that the load could be hooked onto a
crane.
1. Familiarity with load calculation - rRigging equipment must not be
loaded in excess of its safe working load.
2. Sling Protection (Corner padding) - protect sling from sharp surfaces.
3. Understand the principle and determine the of center of gravity of the
load to be carried.
4. Familiarity with standard signs
Failure to rigged the load properly would result to:
• The load became damaged on impact
• The load fell on someone and injure or kill him
• The load fall on a structure causing damage to both property and life
• The sudden release of load causing the crane to be destabilized and topple
1. Slings
• Wire Rope
• Chain
• Webbing
2. Hook
3. Shackle
Observe the following precautions when operating a mobile crane:
• Do not leave a crane unattended
• Do not operate a crane in high or gusty wind conditions
• Do not use flat web slings to raise, lower or suspend a load.
• Do not use a fiber rope slings if a suitable steel wire rope can be used.
• Faulty slings shall be tagged for destruction
• Discard any wire rope with visible number of broken wires
• Check that there are no loose objects on a load that could fall during lifting.
• All lattice boom cranes fitted with outriggers will have the outriggers
operational at all times
• Do not use the crane to drag the load along the ground.
• Do not exert a sideways pull on a shackle or eyebolt.
• Lower the load under crane power.
• The work area should be barricaded off
• Hand held walkie Talkie’s, Hand
Signals & Whistles
• Appointed trained person to give
signals
• Clear communication vital for safe
lifting
• An unstable load, lack of communication, lack of training, and inadequate
maintenance or inspection are major contributors to crane accidents.
• Operators or others working in the area can be victims to “struck by" and
"caught in" injuries.
• Contact with power lines causes many accidents.
• A competent person must inspect a crane regularly to insure it is in proper
order.
• Planning and training reduces accidents.
The Occupational Safety and Health Administration states that most
injuries on construction sites involve excavation cave-ins, power tool
accidents, falls, electrical hazards, and exposure to potentially
dangerous materials.
Hand tools are exactly what they sound like – tools that require manual
labor to use.
Power tools have a power source that allows them to operate
automatically and without human intervention.
The following are the sources of hazards that eventually cause
accidents:
1. Human carelessness
2. Not knowing the right tool for the job
3. Ignorance of safety precautions
4. Failure to maintain/keep the tools properly
5. Not instructed for the correct usage
Hazards of using hand and power tools:
1. Electric shock
2. Particles in the eyes
3. Fires
4. Falls
5. Explosions
6. Falling Tools
7. Free shots
8. Ricochet

  • #28 Material handling is the most frequent cause of workplace injuries, according to a new report from The Travelers Companies, Inc. 
  • #31 A static crane is a permanent/semi-permanent structure fixed to the ground or building that lifts and moves loads along a fixed path. A mobile crane is mounted on treads or wheels and can be moved from job site to job site.
  • #32 On an overhead crane, a horizontal beam called the bridge travels up and down a runway on a track or rail. A trolley and hoist move side to side along the bridge to lift and lower loads throughout a rectangular bay. A gantry crane is a type of overhead crane with a single or double girder configuration supported by freestanding legs that move on wheels or along a track or rail system.  Tower cranes are the cranes you see along city skylines that are used to build tall structures such as skyscrapers.
  • #38 Hooks should last a long time and be strong enough to sustain large loads. Hooks, on the other hand, rely on the weight of other objects to convey them. The items in this list are essential to the crane's ability to lift stuff with the hook. Crane hooks come in a variety of shapes and sizes, depending on the size, weight capacity, and use. It should come as no surprise that crane hooks come in a wide variety of shapes and sizes. The hoist, also known as the hoist drum, is a crane component that provides lift. It is one of the most important crane components. A cranking mechanism, sometimes known as a drum winding, and a wire that raises and lowers the hook make up the hoist. Objects could not be lifted off the ground without the assistance of a hoist. P&H Crane Parts is one of the leading hoist crane parts suppliers. Cranes may travel about the job site using wheels and tracks, depending on the terrain. From moving around a construction site to speeding down the highway, wheels provide more mobility. They are excellent for rough, uneven terrain, but if the job site is soft and muddy, tracks could be the best alternative. Outriggers are crane components that add added safety to the job site when transporting goods. They work in tandem with counterweights to keep cranes upright even while hauling the heaviest of loads. The crane's outriggers extend from the bottom and support it from the ground. They raise the crane off its wheels, eliminating the risk of the crane altering its position due to minor wheel movements. The crane's boom is one of its most prominent features and depending on the crane's size, it may be seen from several miles away. The lengthy steel arm that spans the length of the machine is clearly identifiable as this. From the operator's cabin to the hook, this section of the crane is completed. The boom distributes the load and gives the appropriate height for each load to be lifted. Kobelco crane parts offer great product value, tremendous quality, and overall superb customer service.
  • #40 Note: All cranes with capacity of 16 tonne and upwards have a load indicator in the cab.
  • #47 BSCE 4E
  • #55 Observe the following precautions when operating a mobile crane: Do not leave a crane unattended even for a short time, unless all loads have been removed, lowered to the ground or the engine shut down and brakes applied. Do not operate a crane in high or gusty wind conditions that may put the load or personnel at risk. Always use the cranes load rating charts for guidance, these have wind and weather factors built into them. Do not use flat web slings to raise, lower or suspend a load. Do not use a fiber rope slings if a suitable steel wire rope can be used. Faulty slings shall be tagged for destruction with an Out of Service Tag and returned to the area reliability planner. Discard any wire rope used on a crane, when the visible number of broken wires in any length of rope diameter exceeds 5% of the total number of wires in the wire rope Check that there are no loose objects on a load that could fall during lifting. Pay special attention to the tops of the containers. All lattice boom cranes fitted with outriggers will have the outriggers operational at all times. No slewing of these cranes is to take place unless outriggers are fully extended and in place. Do not use the crane to drag the load along the ground. Severe overloading may result. Do not exert a sideways pull on a shackle or eyebolt. Lower the load under crane power, except where a chain and block system is attached between the crane hook and the load. The work area, equivalent to that of the extended jib, should be barricaded off to ensure unauthorized personnel do not enter the area.
