Laminated wooden heavy equipment mats (HEMs) are increasingly being used at conventional construction sites such as roads and power lines, and in swampy/marshy areas as logging decks and helicopter pads due to growing stringency and enforcement of environmental regulations. Wood is an ideal material to be used in making HEMs because of its light weight, impact absorption ability and low cost. The substantial increase in demand, especially in western Canada, for wooden HEMs has attracted the attention of wood product producers in Atlantic Canada. Truall Inc., in Grand Falls, New Brunswick, is interested in manufacturing and supplying wooden HEMs to natural resources, energy and construction industries across Canada. These HEMs are made of the wood species native to eastern Canada. This project will investigate the potential use of shorter lumber (less than 20ft) and a few fastening patterns in fabrication of HEMs. The specific objective of this project is to identify fastening patterns and eastern wood species that will have potential in fabrication of HEM in the short term. In the longer term the technical information to be generated in this project will assist in the design of a future research project that will lead to an engineering design approach to wooden HEMs marketed by Truall Inc. To achieve the project objective, the project will be conducted using a combination of experimental and finite element modelling work. 3-ft wide and 20-ft long strip HEM specimens will be fabricated to verify the optimal configuration of HEM identified from finite element analysis. The developed product design, incorporating alternative wood species available in Atlantic Canada, use of lumber with shorter length and strategic fastening patterns will be forwarded to Truall Inc., which would revolutionize the HEM industry. No doubt, the increased demand for HEMs in the resource, construction and energy sectors will generate tremendous business opportunities for Truall across Canada.

层压木质重型设备垫（HEMs）越来越多地用于传统建筑 道路和电力线等场所，以及沼泽/沼泽地区的伐木甲板和直升机停机坪， 环境法规的日益严格和执行。木材是一种理想的材料， 由于其重量轻、冲击吸收能力强和成本低，大幅增加 需求，特别是在加拿大西部，对木制高分子材料的关注已经引起了木制品的注意。 加拿大大西洋地区的生产商Truall Inc.，位于新玩法的大瀑布， 为加拿大各地的自然资源、能源和建筑行业提供木质高分子材料。这些HEM 是由加拿大东部的木材制成的。该项目将研究短时间的潜在用途 木材（小于20英尺）和一些固定模式，在制造血红素。这一具体目标 项目是确定紧固模式和东部木材品种，将有潜力在制造的高弹性模量 短期内从长远来看，本项目产生的技术信息将有助于 设计一个未来的研究项目，这将导致一个工程设计方法，以木制高分子材料上市 关于Truall Inc.为达致计划的目的，计划将采用以下方法进行： 实验和有限元建模工作。3英尺宽和20英尺长的带状HEM样本将被 制造以验证从有限元分析确定的HEM的最佳配置。发达 产品设计，结合加拿大大西洋地区的替代木材品种，使用木材， 长度和战略紧固模式将被转发到Truall公司，这将彻底改变HEM 行业毫无疑问，资源、建筑和能源部门对高能量电子的需求增加， 为Truall在加拿大创造了巨大的商机。
