Types of Crane

Tower Crane

Fixed to the ground, this type gives best combination of height and lifting capacity and is used in the construction of tall buildings. To save space, the vertical part of the crane is often built in a well in the centre of the building, which is then converted to a lift (elevator) shaft when the crane is dismantled. A horizontal boom is balanced asymmetrically across the top of the tower. In the case of very tall buildings the tower crane will often jack itself up taller as the building is constructed. Its short arm carries a counterweight of concrete blocks, and its long arm carries the lifting gear. The crane operator sits in a cabin at the top of the tower. A tower crane is usually assembled by a telescopic crane of smaller lifting capacity but greater height, and in the case of tower cranes that have risen while constructing very tall skyscrapers a smaller crane will sometimes be lifted to the roof of the completed tower to dismantle the tower crane afterward. A self-assembling tower crane has been demonstrated, which lifts itself off the ground using jacks, allowing the next section of the tower to be inserted at ground level.

Mobile Cranes 

The most basic type of crane consists of a steel latticework boom mounted on a mobile platform. The boom is hinged at the bottom, and can be raised and lowered by cables. A hook is suspended from the top of the boom by cables and pulleys. The cables are operated by electric motors  

Telescopic crane

This is a type of mobile crane whose boom consists of a number of square tubes fitted one inside the other. When the crane is deployed on site, an hydraulic mechanism extends the tubes to increase the working height 

Loader crane

This is an hydraulically-powered articulated arm fitted to a trailer, used to load goods onto the trailer. The numerous jointed sections can be folded into a small space when the crane is not in use. One of the sections may be telescopic.

Marine Cranes 

Gantry crane

This is a large installation used in container ports and rail freight terminals. The lifting mechanism is mounted on a cross-beam supported on vertical legs which run on rails. This crane can move very heavy loads.

Crane Safety Management

Join Systems Crane Rental is here to help you for all you lifting needs!  From planning stages all the way up to making the lift.  We can help you calculate loads and provide drawling to help you be successful.  One of those tools is a simulation program that generates graphical displays of the lifting task, including the selected crane with lift obstructions, and allows the user to simulate the lift and check all clearances (boom, tail-swing, tip height and hook height). Crane specifications, capacity charts and site views (both plan and elevation) can be generated and printed within minutes of entering the basic lift specifications

Foundations, Shoring and Bracing, Structural Integrity Review

Ÿ     No tower crane shall be erected at a project except in accordance with the safety regulation. 

Ÿ     The foundations supporting a tower crane shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and shall be constructed in accordance with the design regulation. 

Ÿ     The shoring and bracing that support a tower crane or tie it in place shall be designed by a professional engineer in accordance with the crane manufacturer’s specifications and shall be installed in accordance with the design

Ÿ     The structural engineer responsible for the structural integrity of the building or structure shall review the design drawings for the foundation, shoring and bracing for a tower crane before the crane is erected at a project to ensure the structural integrity of the building or structure. 

Ÿ     The structural engineer who reviews the design drawings shall sign the drawings upon approving them

Ÿ     The constructor shall keep at the project while a tower crane is erected a copy of the signed design drawings for its foundation, shoring and bracing and any written opinion about the drawings by a structural engineer

 

Pre-Erection Inspection/Non-Destructive Testing 

Ÿ     Before a tower crane is erected at a project, a professional engineer or a competent worker designated by a professional engineer shall inspect its structural elements and components using methods of non-destructive testing approved by the Korean Regulations to determine their structural integrity. 

Ÿ     The professional engineer conducting an inspection or under whose direction an inspection is done shall prepare a written report of the test results and shall sign and seal the report. 

Ÿ     The constructor shall keep the report at the project while the crane is erected.   

 

After-Erection Inspection 

Ÿ     A professional engineer or a competent worker designated by a professional engineer shall visually inspect for defects the structural elements and components of a tower crane.  

Ÿ     No tower crane shall be used until any defects found during an inspection are repaired in accordance with the instructions of the crane’s manufacturer or a professional engineer. 

Ÿ     A professional engineer or a competent worker designated by a professional engineer shall inspect a tower crane that has been repaired to ensure that the defects are corrected. 

Ÿ     The professional engineer conducting an inspection or under whose direction the inspection is done shall prepare a written report of the test results and shall sign and seal the report

Ÿ     The constructor shall keep the report at a project while the crane is erected.   

Operational Tests

Limit Switches and Overload Limit Devices 

Ÿ     A tower crane shall have automatic limit switches and automatic overload limit devices that prevent            

Ÿ     In addition to automatic limit switches and overload limit devices, a tower crane shall have such other switches and devices as the manufacturer specifies

Operational Tests on Switches, Devices 

Ÿ     A competent worker shall perform operational tests on a tower crane to ensure that its automatic limit switches and overload limit devices are installed and functioning in accordance with the manufacturer’s specifications, if any

Ÿ     Overload limit devices for a tower crane shall be tested using test blocks designed for the purpose that have their weight clearly marked on them. 

Ÿ     The test blocks shall be kept on the project while the crane is erected. 

Slewing 

Ÿ     A tower crane boom shall be able to slew freely when the crane is unattended except when,

    (a) the boom may collide with another crane, a structure or another object; or

    (b) to slew freely would be contrary to the written procedures of the crane’s manufacturer

They should be able to make decisions and they must be able to give and interpret hand signals and radio communications correctly when operating a crane, and they should be skilled at observing details on the ground. Crane operators also need to have first aid skills.

Knowledge

Crane operators must know the meaning of different hand signals being given from the ground. They must know about the safety regulations that govern crane operation (such as environmental and health and safety legislation, road regulations and vehicle weight permits), the weight limits for various cranes and how to maintain the cranes they use. They should also have some knowledge of construction methods and materials

Personal Qualities

Crane operators should be responsible and careful at all times when operating a crane. They need to be patient, persistent and attentive. Crane operators should work well independently and in teams.
