Semi-gantry crane

We have designed a semi gantry crane to meet customer specifications. Semi-gantry crane is usually the site of the plant or economical solution. We can provide single girder cranes and double girder cranes, lifting capacity depending on your needs. Advantages semi gantry crane is usually mounted below the existing overhead traveling crane. So it can cover a wide range of floor area. We can see from the picture, how semi gantry crane is installed below the overhead mobile cranes. Thus, semi-gantry cranes below the working platform can work independently outside grab crane

Eliminate manual lifting

Eliminate manual lifting: empower a single worker to move loads from workstation to workstation.Supplement or replace multiple jib cranes and/or forklifts.Free-up your existing overhead crane for larger loads: use your freestanding Workstation Bridge Crane to quickly move loads up to two tons Install flexibility: freestanding bridge cranes are ideal for rented facilities when workflow changes are possible; they are easily relocated and typically require only a standard concrete floor for installation.These durable, super efficient bridge cranes can be fully customized,including telescoping or cantilevered bridges, single girder bridge cranes tractor drives, mixed capacity systems, and more.

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.

electric wire rope hoist manufacturer

The above costs accounted for about 30% electromagnetic overhead crane of the overall cost. Metal structure according to its structure can be divided into the solid-web (the box structure made of steel plate, also known as) and lattice (generally made of steel, electric wire rope hoist manufacturer common root and lattice column), composed of the basic mechanical components of crane metal structure

electric wire rope hoist manufacturers

Wrap rate mechanism, when the 2-for-4 magnification switching magnification is not in place, crane spare part did not pay attention to check, or no increase insurance sales, in lifting the pulley activity will suddenly drop, causing a major accident.The twisted rope play rope serious disorder, electric wire rope hoist manufacturers not immediately removed, forced to use.

The weight of the metal structure

single girder overhead crane Metal structure is a metal rolling steel (e.g., Angle steel, channel steel, i-steel, steel pipe, etc.) and steel plate as a basic building block, wall mount jib crane through the methods of welding, riveting, bolt connection, according to certain rules of connection, under gravity and load of the crane steel structure. The weight of the metal structure about accounts for 40% ~ 40% of the weight, heavy crane can reach

due to the inertia of the system could not produce coasting fall

Do not pay attention to maintenance from the weight of limiter does not regulate the limiter from the weight on the use of, electromagnetic overhead crane or even deliberately do not, or increase the limit value, so that from the weight of limiter should not restrict the protective effect.The lifting mechanism brake not adjusted too loose. When overweight high speed decentralization, over head cranes due to the inertia of the system could not produce coasting fall.

With the rapid development of China's urbanization

With the rapid development of China's urbanization, the single girder bridge cranes  with its strong scalability, large capacity characteristics, in terms of construction, cargo handling and other playing an increasingly large role. However, due to the risks involved in the field of mechanical and electrical construction cranes and aerial work operation, etc., crane supplier it also became a construction safety Each crane driver must pay attention to the matter

jib crane manufacturers

jib cranes specifications, all varieties, whether you are lifting weight, rotation angle, arm length and function, what kind of requirements, we can provide you with the best solution, even we have with double spiral arms jib crane. All specifications have a common advantage: light weight, arm length, lifting large. Jib crane can be equipped with s...upply electrical accessories, electric hoist and trolleys. Other accessories include increased mounting plate, chemical bolts.jib crane manufacturers

semi gantry crane

This kind of crane motor are mounted on a chassis, semi gantry crane chassis has two axle and four large diameter cross-country decorative pattern of the tire. Four wheels are the driving wheels and the steering wheel, when on the uneven muddy construction site transfer station, eot cranes the four wheels are passing the power

The difference is the structure grab bucket crane

electric wire rope hoist manufacturerOff-road tyre crane in the workDeveloped a kind of crane is 70 s, its similar to tyre crane hoisting function, also can undertake no leg hoisting and lifting. The difference is the structure grab bucket crane of the chassis and the unique chassis structure caused by the improvement of the performance of the drive
