sarens group www.sarens.com Sarens Climbing Tower SCT The SARENS CLIMBING TOWER is designed for lifting heavy loads in the construction, petrochemical and offshore industries. The system is suited to using either climbing jacks or strand jacks to provide the lifting force. This document outlines the general specification of the system. Detailed engineering, risk assessments and method statements must be prepared for each project.

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen General description The SCT system is modular comprising standard interchangeable components. The tower leg sections are either 5.7 metres or 11.4 metres long and the required tower height is achieved by combining tower sections. The tower legs are set at 3.5 metre centres and tied together on each face using tubular braces with pin connections. A stabbing guide at the end of each tower section leg provides for quick alignment and erection and standard bolts are provided to resist tensile and shear loads in...

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen Jacking equipment The SCT utilises two types of jacking equipment depending upon the type of lift. Climbing jacks Each tower is suitable for mounting one, two, three or four 200mm climbing bars on the front face. Each 200mm climbing bar will take a 450 tonne capacity climbing jack giving a lifting capacity of up to 1800 tonnes per tower depending upon tower configuration. Each climbing jack comprises an upper wedge unit, a lower wedge unit and a pair of solid hydraulic rams which sit between the wedge units....

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen Strandjacks The strandjacks can be mounted on frames at the tower top or on a cross beam between tower tops. Each jack consists of a bottom anchor assembly, a main hollow hydraulic piston and a top anchor assembly. Each anchor assembly consists of a series of tapered wedges, which will automatically form a mechanical lock against the lifting strand. The operation of the hollow hydraulic piston moves the lifting strand through the jack, automatically transferring support between the top and bottom anchor...

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen Tower system foundation The tower system is provided with a standard base frame. There are several options for mounting this frame to provide a strong and stable foundation to the towers. The choice of tower foundation will depend on the constraints of each site. The two primary options are as follows. Concrete foundation The base frame is located on a concrete foundation. The foundation may be a specially constructed and temporary or an extension or modification of existing permanent foundations. Base...

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen System capacity The SCT is designed to work generally as a 2 tower free-standing system, but its modular nature means that it can be configured in an almost unlimited number of different combinations.The maximum Load that can be lifted is limited by a number of factors as follows: • The weight of any additional temporary works and equipment reduces the net lifting capacity. • The lifting capacity of the climbing jacks on each tower. 4 No DL-C450 climbing jacks can be used on each tower, giving a maximum...

SARENS CLIMBING TOWER (SCT) Kenmerken Caracteristiques Specifications Kennzeichnen The following safe working load chart is provided for guidance only. For precise capacity the lift needs to be fully engineered for each project with consideration of all factors. The table is based on gross lifting capacities including weight of load plus strand, lifting beam etc. Configuration is two towers at 20 metre spacing with the vessel central to towers. Maximum lifting wind speed is taken as 20m/s and maximum storm wind 40m/s. Guys are assumed as 4 x 185 tonne capacity. No. 11.4m Tower Strand Jacks...
