Crane

Cranes are categorized by structure and usage, depending upon usage, area and customers’ requirements. ALLA has skillfully experienced engineers who are able to design cranes to suit customers’ usage and needs. Cranes are categorized as follows.

OverHeadSingSingle

Single-Girder Overhead Crane

Crane is widely used in small and large factories which require small load capacity. The recommended load capacity and span are 1 to 25 tons and 6 to 22 meters, respectively. Several lifting ranges are available to suit customers’ requirements. Customers have two options for directional control system (1) Double speed – has slow and fast speed in the same direction (2) Inverter – employs electrically controlled motor speed, which enables smooth travel. The selection of control system depends on customers’ needs. We have experienced team to advise and design crane to suit customers’ requirements.

OverHeadSingDouble

Double-Girder Overhead Crane

This crane is widely used in heavy industry such as steel coil warehouse, car assembly plant, power plant. Double crane is employed to accommodate high load capacity requirements. The recommended load capacity is 2 to 250 tons and the span is 10 to 35 meters. various lifting heights are available to suit customers’ needs. We have experienced team to design crane to suit customer’s requirements and operator’s highest safety.

7 Suspension Crane Single Girder

Underhung Crane

This crane can be designed to have single or double girders. It is suitable for industry that needs area under the roof as much as possible such as airplane hangar.

Gantry-Single

Single Girder Gantry Crane

This crane is suitable for outdoor area and in factory with building pillars that are not designed to support the installation of overhead crane, thus requiring Single Girder Gantry Crane. Similar to Single Girder Overhead Crane, Single Girder Gantry Crane is used in industry, which requires low load capacity in the range of 1 to 25 tons with 6 to 22 meters in spans. We have experienced team to design crane to suit customer’s requirements and operator’s highest safety.

Gantry-Double

Double Girder Gantry Crane

This crane is suitable for outdoor area and in factory with building pillars that are not designed to support the installation of overhead crane. Double Girder Gantry Crane has the same feature as Single Girder Gantry Crane, except the first has double girder to increase load capacity to 2 to 250 tons with 10 to 35 meters in spans.

5 Semi-Gantry Single Girder

Single Girder Semi Gantry Crane

This crane is suitable for factory. Upper traveling rail is installed to building pillars and the lower one is installed on the factory’s floor. It can be designed to have two levels. Single Grinder Semi Gantry Crane generally has 6 to 22 meters spans and load capacity 1 to 25 tons.

6 Semi-Gantry Double Girder

Double Girder Semi Gantry Crane

This crane can be installed both indoor and outdoor. It has the similar qualifications to overhead crane and Single Girder Semi Gantry Crane. Double Girder provides higher load capacity with more spacious working area. It suits industry, which does not require high load capacity in the range of 2 to 250 tons and 10 to 35 meters in spans.

9 Pillar Jib Crane

Pillar Jib Crane

This crane is suitable for lifting load within area of its arm’s length with restriction that a slew range depends on distance between walls in the factory

10 Wall Mounted Jib Crane

Wall Jib Crane

This crane is suitable for lifting load within area of its arm’s length, which is similar to Pillar Jib Crane. The difference is that Wall Jib Crane is installed to building pillar instead of having its own pillar with restriction that the slew range depends on distance between walls in the factory.

11 Wall Crane

Wall Crane

This crane is suitable for lifting load along factory wall. It has a set of three legs and six wheels and runs on double-deck traveling rails. This set of crane legs and wheels is installed to double-deck rails, which are also attached to factory building pillars. The crane sticks out from the rails and can freely lift load or goods. Similar to Semi Gantry Cranes, this Wall Crane is used for lifting load along factory wall, except for more convenient to use.

12 Monorail

Mono Rail Crane

Installed hoist runs on the single rail designed in accordance with production line. The rail is a single rail which can be designed as straight or curve rail. Hoist can move forward, backward or along curved rail. Load capacity is 0.5 to 1.0 tons. With this design, hoist can only move in four directions – forward, backward, upward and downward.
