There are two carrier-beam: one is vertical to main girder, one is parallel to main girder. You can choose you need.

QL Electromagnetic Overhead Crane Features

(1) In General

• Good quality, high production efficiency, few maintenance;
• High loading strength, high working class;
• Flexible operation, safe and reliable.

(2) Main Body

• Double girder, welding box beam, camber meet national standard;
• Adopt high quality carbon steel, Q235B or Q345B; (similar as Fe37 or Fe52);
• Main welding submerged arc welded automatically, nondestructive flaw detection;
• All metal materials(main girder,end girder, trolley)are chosen according to the national standard.
• Steel plate material requirements shot blasting before cutting, derusting grade reach Sa2.5 above.

(3) Crane and Trolley

• Crane protection grade is IP54 or IP44, F/H grade insulation
• Use special reducer, Hard-toothed surface, Reducer shaft inspected by Ultrasonic testing;
• Main hook's reducer shell welding, taking a seal grooves, shaft top sealed well;
• Use YWZ model electric&hydraulic pushing rod often-close brake, the main lifting use double brake;
• Drum material is 16Mn, made of steel.drum shaft and cylinder body are welded and inspected by ultrasonic testing.
• The wheel tread are treated by heating processing;
• Pulley block are made of rolled steel;
• The tooth shape coupling, and the material of the 40 Cr, forging steel;
• All buffers use polyurethane (pu) type, on same span,
• Buffers must have same height;
• Hook use forged material, nondestructive flaw detection, fortify the slot device.

(4) Electric System

• All electric are SIMENS & SCHNEIDER;
• Crane can use safe slipping line to get power , slip line is located against the cab;
• Wire ropes are put in the steel trough or metal tube;
• On dangerous points equipped with protection device;
• The wire ropes are closed in hard steel tube or metal soft tube, line pipe and trough are welded on crane's metall construction.
• Trolley's cable devices are fixed inside of walking board;
• Bridge lighting use special crane damping lamps. Set special lighting circuit.

(5) Protection Devices

• The crane and trolley have travelling stop block, hook have double limiters,one of them is on drum
• Crane equipped with audible and visible alarm, and slipping line protection device prevents any danger to person;
• A cage is fixed on slip line side under the main girder,convenient to repair the slip line.
• All of the connection axis, floating shaft all has the shield to prevent danger.
• All doors on crane have interlock protection device, when the door is open,crane will stop travelling.

(6) Operation Device

• Ground control and cabin control;
• Special cabin for bridge crane or capsule driver room, open vision comfortable operation;
• The cable has open style, close style, can fixed on left or right;
• The open direction includes end open, side open or top open;
• The cabin has special small room and the capsule cabin;
• Ground control has handle and remote control; do not need to set up special driver;
• Users can choose as you need.
