LIFTBOY Electric Overhead Travelling Cranes are designed and manufactured in accordance with IS:807, IS:3177 code of practice for design and manufacturing, erection & testing of structural portion of crane and IS:3177 code of practice for design of overhead cranes.
Our cranes are designed considering adequate factor of safety with respect to appropriate duty classification.
Our product range includes Single Girder EOT/HOT Cranes, Double Girder EOT/HOT Cranes, and Under Slung Cranes.
LIFTBOY Cranes are available in wide range of capacities starting from 1 ton, up to 100 ton.
Following are the major features of this range:
Efficient in operations
Standard, ISMB, Lattice girder or Plate Box Girder Section, well designed and fabricated as per IS:807 and IS:3177 and fabricated out of IS:2062 Freely Weldable Quality Material.
Fabricated out of standard steel sections or plates to support the main girder at both the ends. The end carriage are fitted with double flanged crane wheel mounting with L Block housing or suitable open red, made of high quality steel casting or forged steel, running on ball/roller bearings.
Gearboxes & Couplings
Graded C.I./Fabricated Gearbox housing are machined to close tolerance (± 0.02 on center distance, 0.01 deviations on bore form & H7/H6 bore tolerance. Gears and pinions from forged C55/40Ni2Cr1Mo28 are precision hobbed for correct involute profile. Bearings (ball and roller) from manufacturers authorized stockists) support pinion & O/P shaft are assembled by highly skilled technicians who have been building machine tools with us for over years. O/P shaft for main/auxiliary hoist gearboxes are forged integral with single crown coupling resulting in almost maintenance free hoisting unit. CT & LT gearboxes with single/double hub coupling from C45 are precision cut form and with minimum clearance, yet taking care of angular, axial misalignment during assembly. Aligning I/P, O/P gearboxes shafts with motors, drum or floating shafts is done with care as if these are rigidly connected.
Crane wheels forged, machine true (tread diameters held true to ±0.1) on precision machines are subsequently hardened and tempered to 250-300 BHN to give a long life to travelling machines. Wheel axels are ground to hold very close tolerance at bearing ends, wheel zones and coupling hub connection. This helps in easy changeover of wheels during maintains as interchangeability is guaranteed during manufacturing.
Rope & Hook
Rope to IS:2266 with minimum factor of safety 6 & hooks proof load tasted to IS:8610/IS:3815 are bought and certified.
Crane Duty, three phase, 415 Volt, 50 Hz. AC Squirrel Case Induction Motor with high starting torque and TEFC continuously rated. Motors are suitable for frequent reversing and are of standard makes like Crompton, Bharat Bijlee, NGEF etc. Slip-ring motors are also available on special applications.•
Brakes AC Electromagnetic Shoe/Disc Brakes are used for compactness and instantaneous braking characteristics. Hoisting brakes are selected with minimum 150% of running torque as per IS:3177 & IS:3198. Electro-hydraulic Thruster Brakes are also used on special applications.
Dust Proof, well designed control panels, fitted with switch gears, fuses and step-down transformers etc. are used. Push Button Pendent, Station Operating Line Contactors, Press-to-run Button for each direction of motion with Direction Legends are used. Safety Limit Switches are provided for stopping the lifting operation and lowering motion at the extreme position of the hook block.
We are well known manufacturers of high quality of HOT Cranes. These cranes are made in accordance with 1SS: 226 I or 1SS: 2062 standards ensuring high resistant to vibrations. These state of art cranes are durable, robust and reliable. Since these are made out of class A raw materials like crane and hoist duty motors and other electrical components, therefore, these cranes function flawlessly. We lay special stress on design of the cranes to be such that they are easy to use and user friendly. Our overhead HIT cranes are highly in demand in local as well as overseas market due to factors like these have 100% radiography welded joints. The cranes have high quality brakes, and are very resistant to rust.
These are used in following areas:
Heavy fabrication unit
Large water works
With vast experience and knowledge we are engaged in offering a comprehensive range of Bridge Cranes , Double Girder Bridge Cranes & Single Girder Bridge Cranes from 1 Ton to 20 Tons. These handle the load in an efficient manner and have a bridge with end trucks. Our products are developed using high grade material which is procured using from reliable vendors of the market. In addition to this, these are highly appreciated among our clients due to their superior finish, resistant to corrosion and competitive prices.
We have carved a niche for ourselves in the industry by offering Under Slung Crane, which are manufactured without any technical error. Leveraging on our highly equipped fabrication capabilities, we have developed our expertise in offering a customized range of:
Under Slung Overhead Cranes
Under Hung Overhead Cranes
Suspension Type Single Girder Overhead Cranes
These are used as a material handling equipment in host of industries.
We are leading manufacturers of self propelled Gantry Cranes. These run on rails installed at ground level. We manufacture both the Single Girder type and Double Girder type of gantry cranes. We can also customize these cranes according to your specific requirements. Our cranes are largely used in construction works, Ports and harbors, small and compact workshops, worksites with changing or large bay lengths. These cranes are easily movable and especially useful where only part utilization of workshops has to be done.
