Backhoe Trench Box

The Backhoe Trench Box is a lightweight yet robust solution for small trenching applications. With a load capacity of 20 kN/m2, it can be used to depths of 4 metres in most soil types. It's ideal for use on building sites and construction projects where small excavator handling is essential. Developed to meet the needs of the contractor when using smaller 180 degree backhoe rubber tyred excavators, this box is supremely light yet provides solid support.

Typical base weight from 740kgs
Internal widths from 0.3 to 2.1m
Suitable for excavation depths up to 4.0m
Modular construction and simple pinned strut arrangement
1.2m clearance under the bottom strut
Handrails available

The Backhoe Trench Box is an alternative to the standard Groundforce Trench Box. It has been developed to optimise strength whilst ensuring its weight remains low enough to be handled by smaller excavators on site. It is capable of supporting trenches up to 4m deep when a base module is connected to two top extension units.

Trench widths of up to 2.2m (earth to earth) can be achieved by using a variety of fixed length strut extensions. These are connected to the box plates using a simple pin arrangement for speedy on-site assembly.

Trench Boxes: Typical Installation Methodology

This quick and easy method ensures ground stability within a trench and helps minimise the excavation area to avoid damage to neighbouring structures and utilities in the ground. This methodology is best suited for trench boxes with shorter struts, if you use a trench box with long struts then other methods may be more suited, if you have any questions on different methods you can use contact our technical department.

Trench Box

A trench box is generally the first choice for the rapid shoring of trench runs due to the speed and simplicity of installation. They are typically suitable for use in trenches up to 4.9m wide x 6.6m deep in reasonable ground conditions, they are not recommended in unmanaged, waterlogged ground. Groundforce offer a wide range of trench box sizes with various strut types, providing a safe solution on site. A trench box is versatile, cost-effective and provide an excellent way of protecting workers from excavation wall collapse while carrying out groundworks. They can easily be stacked and used in multiple runs, which also makes them the ideal shoring method for continuously supporting an extended length of trench. Some of the key benefits are:

EdgeSafe

EdgeSafe is a lightweight mesh barrier system designed to provide light duty edge protection to a trench box, sheeted or timbered excavations. It can be used on short or long continuous runs and has been designed in accordance with BS EN 13374: 2004 Class A.

EndSafe

EndSafe is a structural steel panel designed to close-off the end of a trench box or manhole box to safely retain the backfill and prevent accidental dislodgement of loose material into the excavation. They also provide a barrier to prevent unauthorised access to the excavation and remove the need to improvise with other unsuitable equipment such as steel road plates or timber.

Lifting Chains

Lifting Chains are specifically configured for lifting Groundforce shoring equipment and are available in a range of lengths, legs and capacities.
