Double girder bridge crane

double girder overhead travelling crane from the straight track, crane girder, lifting car, power transmission systems and electrical control system is particularly suited to large hanging from the weight of the plane and a large range of material handling.
He said it should be a bridge crane, single girder bridge cranes points and double-beam bridge. Girder cranes is no such classification.
Girder bridge crane and crane different weights, beam is 5t and below, the bridge is 5t and more

side beam is formed by bending steel or steel welded

Press the tray-bearing and suspended two. The former car beam electric hoist manufacturers along the orbit; the latter at the plant along the suspension bridge truss crane orbit. Single girder overhead crane sub-manual, electric two kinds. Manual single-girder overhead crane operating speeds lower bodies, since the weight is small, but the quality of their small, easy production, low cost, suitable for small amounts without power after handling, less demanding on the speed and productivity occasions. overhead bridge cranes with manual monorail car as the car is running, hand pull gourd as a lifting mechanism, the bridge from the main beam and end beam components. Main beam generally use single beam, side beam is formed by bending steel or steel welded

Girder cranes editing rules

industrial overhead cranes must be done by specially trained and approved by the competent authorities of the person to operate.
Crane operators must be familiar with the mechanical and safety performance of their own operations crane, crane familiar with and strictly implement the rules and safety regulations, master lifting skills, attention must be focused operation, obey orders, exercise caution.
When the operator operates the crane, you must obey the command of the command staff, and for the emergency stop signal, no matter who issued should be implemented immediately.
Before each use of a single girder bridge cranes, the crane operator must first check the brake, hook, wire ......

single girder bridge cranes

single girder bridge cranes girders word to use more steel or composite section steel and steel sheet type. Often lifting trolley chain hoists, electric hoist or hoist lifting mechanism components as assembled. Electric single-girder bridge crane operating speeds, higher productivity than the manual, from the weight as well. electric magnetic overhead crane from the bridge, traveling mechanism, hoist and electrical equipment and other components

Selection gantry crane

Under normal circumstances, from the weight of 50t or less in the span of less than 35m, single girder gantry crane no special requirements, should choose a single main beam. If you require a large gate leg width, high operating speed, or frequent lifting heavy items, grew up in pieces, then should choose double girder gantry crane

tire cranes, crawler cranes.

In bridge engineering used in lifting machinery, depending on its construction and performance, and can be divided into small light lifting equipment, bridge type crane and grab cranes, cable cranes four categories. Small light lifting equipment such as: Jacks, pneumatic hoists, electric hoists, balancing gourd (aka balance suspended), winches, etc.. Bridge type crane as beam cranes. Such as fixed jib type crane slewing cranes, floor mounted jib crane, truck cranes, tire cranes, crawler cranes.
