设计验证和技术计算

几乎没有什么设计规则能适用所有的起重机轨道安装。关于起重机和轨道安装基础设施的设计,其设计准则非常琐碎细微。有着丰富经验的gantrail开发了具体的检查措施使得设计付诸应用时能够充分考虑这些规则。这不仅使设计既遵循了国家和国际准则,而且还填补了这方面的空白。Gantrail的方法永远用计算做支持。

安装前测量

起重机和大型设备在轨道上运行,对轨道的精度要求非常严格。允许的公差要比正常的土木工程要苛克。因此在轨道安装之前对工程机构做一项调查是明智的。某些情况下,由于轨道已运行多年,轨道下方的结构和基础会发生移动。修复工作开始之前,对工程做测量也非常有必要。

任何规模的工程

Gantrail参与了很多行业了规模大小不一的项目。港口集装箱和钢厂需要数公里长的起重机轨道用于承载最重型荷载,与之不同的是自动化仓库是轻型轨道安装,要求轨道有非常高的精确度以防止起重机晃动。Gantrail逐一攻克了世界上所有艰难工况的各种项目。

Crane Rails

Crane rails come in a wide range of shapes and sizes. The designs have been developed to meet individual countries requirements with some being squat and wide and others are taller and similar in shape to railway rails but they are all more robust. There are now only a few ‘families’ of rails with similar shapes and a range of sizes. Most crane rails range in head width from 45mm to 150mm. A common feature is a thick web to carry the load to the base. There are also a range of steel metallurgies. At their most basic they are made from high carbon manganese steel but some are more highly alloyed. They are all difficult to weld. Gantrail will normal comment on any chosen rail for a project or propose the most suitable choices.

Crane Rail Pads

It is an advantage if a rail can rotate a small amount around an axis along its length. This allows the rail to take up a position that matches the wheel and as a result reduces the compressive stresses in the tread of the wheel and the head of the rail. Gantrail supply steel reinforced crane rail pads that allow this. They have been proven in thousands of applications for over 50 years. They also eliminate the metal to metal contact and reduce corrosion between the rail and its support.

Crane Rail Fixing Clips

It is not practical to fasten crane rails rigidly to the support on which they are mounted. Rails need to be adjusted to the correct position and to be able to move small amounts along the support. They also need to be able to rotate about an axis along their length. But they should be fixed rigidly from significant sideways movement. Gantrail have developed a range of adjustable crane rail fixing clips for all sizes of rail. These can be fastened by means of bolting or by welding to a steel surface. Some in the range will resist the highest expected loads but other are compact and light and are for smaller applications.

Steel Soleplates & Bolts

Most sole plates look like simple plates of steel with many holes. But the challenge for the track system designer is to combine the requirements of the concrete foundations with its reinforcement and expansion joints with the needs of the rail system. Hole positioning is most important. There may be a need for rail fixed points and earthing. There is also a need for high accuracy sometimes combined with corrosion protection. Bolts for fixing sole plates need to be made such that they will not rotate on being tightened. Gantrail also supply more sophisticated system which allow for releveling a rail after installation.

Grout

The upper surface of poured concrete it very weak and will not support the loads imposed by a steel crane wheel. The surface needs to be cleared of soft material before the gap between the structural concrete and the steel sole plate.is filed with high strength grout. Gantrail supply two types of grout for the majority of applications. Some cases require the strength of an epoxy based system whereas others can accept special cement bases grouts. Smaller qualities of fast curing polyester grouts are used to secure bolts in premade holes in concrete.
