Pitless Type Weighbridge

Pitless type


Overview

It is more suitable where the excavation work for foundation is difficult or construction of pit is expensive. Since the structure is above ground level, vehicles can approach the weighbridge only from two directions where the ramps are provided. This type of weighbridge requires more space.

In Pitless Type Weighbridge RCC ramp work must be required at least 3 meters for both sides for easy movement of vehicle

 

 

Robust Load Cells and Digitizers The most important components of an electronic weighbridge are the loada cells and digitizers
Highly Durable Girders And Plates A truck to be weighed is directly driven to the platform of a weighbridge and hence, the platform is subjected to the entire load and vibrations created by a moving truck. 
Reliable Mounting Assembly For Load Cells

The next most important component is the mounting assembly for load cells. This transfers the load from the platform to the load cells. This is a cradle assembly which is free to move in the horizontal axes and hence takes all side loads generated due to the vehicular movements on the platform. The mounting assembly consists of three parts namely, the Bottom Plate, Rocker assembly and Top Bracket

Low Resistance Cables And Weather Proof Junction Box

The signal from the load cells (in milli-volt) is carried to the digitizer, in the control room, through a 4 - core shielded cable. The cable has a very low electrical resistance and hence, no loss of signals. The cables from different load cells, in a weighbridge, meets in weather proof junction box. The junction Box is of fully molded type and houses the necessary terminal blocks for interconnection of load cell out puts. The Junction box also carries a set of surge arrestors, to protect the entire system from lightning and electrical surge

 

 

 

Features and Benefits

Weighbridge Structure Modular construction with high strength reinforced mild steel, the design comprised of two main raised side longitudinal beam members and transverse channel and joist members. Platform plates, which are stressed members of the structure have a patterned slip-resistant chequered plates
Bumper Stops Horizontal restraint, both longitudinal and transverse impact movement are limited by four units of longitudinal and four units of transerverse bumper stops and are virtually unaffected by everyday abuse to withstand routing shock and jolts without going out of adjustment and only vertical forces are measured by the weighing
Free Motion Self alignment free motion strut type movating kits made of special alloy steel are used to minimise wear and tear on the load cells. The construction of the mounting kit provide for a pivoting point of contact at the spherical top of the load cell and ensure that the forces are applied centrically into the top of the load cell
Strength Strength is based on loads quoted uniformly distributed
Environment Resistant to dirt and moisture consistent with conditions pertaining to well drained out door istallation
Junction Box  Heavy gauged metal and moisture with full IP65 environment protection enclosure complete with multi-cored shield cable standard at 10M length
Indicators/Printers

The indicators supply by us are manufactured with the strictest care to ensure consistently accurate weighing and withstand shocks and overloading. Large shear beam load cell with mounting attachments included for easy installation. The design is easy to maintain and economical because of few moving or rubbing parts. 

 

 

Type Of Scale And Pit 

TYPE OF SCALE

PITLESS TYPE

Cost Less expensive due to less construction work
Service & Scale Repairs Less difficult or costly and serviced from above
Clean Out Quick and easy, done with a water hose or compressor from the side
Scale Ispection Can be performed by simply walking around the perimeter or the scale
Restrictions Or Hazaeds Some states require specified clearances underneath scale
Approaches 10' Flat and level
Ramps Typically 25' long on each end of the ramp. Requires more real estate to install and operate
Electricity Needed None
